If you or someone you love has been diagnosed with pulmonary hypertension, you may have questions about what it means, how serious it is, and what treatment can help. Here are straightforward answers to common patient questions.

1. What exactly is pulmonary hypertension?

Pulmonary hypertension (PH) means that blood pressure in the arteries carrying blood from the heart to the lungs is abnormally high. This makes the heart work harder to pump blood through the lungs. Over time, it can strain the heart and affect everyday activities.

2. Why am I getting breathless when I walk or climb stairs?

Shortness of breath during activity is one of the most common early symptoms of pulmonary hypertension. When blood flow through the lungs is restricted, the heart and lungs may struggle to meet the body’s oxygen needs during exercise. However, breathlessness can also be caused by asthma, COPD, anaemia, and other conditions, so proper assessment is important.

3. What are the warning signs of pulmonary hypertension?

Symptoms may develop slowly and can include:

• Breathlessness during everyday activities
• Feeling unusually tired or weak
• Dizziness or feeling faint
• Chest discomfort
• A racing heartbeat
• Swelling in the feet, ankles, or abdomen

Symptoms that are new, persistent, or worsening should be discussed with a doctor.

4. What causes pulmonary hypertension? Have I done something to cause it?

Pulmonary hypertension can be associated with heart disease, lung conditions such as COPD, chronic blood clots in the lungs, certain autoimmune diseases, or inherited factors. Sometimes, no clear cause is found. Having the condition does not necessarily mean you did anything to cause it.

5. Is pulmonary hypertension the same as high blood pressure?

No. Ordinary high blood pressure affects arteries throughout the body, whereas pulmonary hypertension affects the blood vessels between the heart and lungs. The two conditions require different tests and treatments.

6. Is pulmonary hypertension dangerous?

It can be serious, especially if it progresses without treatment. High pressure in the lung arteries makes the right side of the heart work harder and may eventually lead to heart failure. The outlook varies depending on the cause, severity, and response to treatment.

7. How will my doctor find out if I have pulmonary hypertension?

Your doctor may review your symptoms, medical history, and examination findings before recommending tests. These may include an echocardiogram, ECG, blood tests, chest X-ray, and lung function tests. A right heart catheterisation may be needed to confirm the diagnosis.

8. Does an echocardiogram confirm pulmonary hypertension?

An echocardiogram can estimate the likelihood of pulmonary hypertension and show how well the heart is functioning. However, it cannot always confirm the diagnosis. Right heart catheterisation is generally used to measure pressures directly and confirm pulmonary hypertension when indicated.

9. Can pulmonary hypertension be cured?

That depends on its type and cause. Many forms require long-term treatment rather than a permanent cure. However, some patients with chronic blood-clot-related pulmonary hypertension may benefit substantially from specialised procedures or surgery. Early assessment helps identify the best options.

10. What treatment is available for pulmonary hypertension?

Treatment depends on the specific type of pulmonary hypertension. It may include targeted medicines, oxygen when needed, treatment of an underlying heart or lung condition, or procedures for selected patients with chronic blood clots. Your doctor will choose treatment according to your diagnosis and individual needs.

11. Will I need to take medicines for the rest of my life?

Some patients need long-term treatment and regular monitoring. The duration depends on the cause and severity of the condition and the response to therapy. Never stop or change prescribed medicines without speaking to your doctor.

12. Can pulmonary hypertension lead to heart failure?

Yes. If the pressure in the lung arteries remains high, the right side of the heart may become enlarged or weakened. Increasing breathlessness, worsening swelling, or rapid weight gain due to fluid retention should be reported promptly to your healthcare team.

13. Can I exercise if I have pulmonary hypertension?

Many patients can benefit from carefully planned physical activity, but the right level varies. Ask your specialist which activities are safe for you. Supervised rehabilitation may help some patients. Stop activity and seek medical advice if you experience chest pain, severe breathlessness, or dizziness.

14. What changes should I make to my daily routine?

Taking medicines as prescribed, avoiding smoking, attending follow-up appointments, eating a balanced diet, and staying active within your doctor’s recommendations can help. Ask your healthcare team whether you need to limit salt or fluids, and discuss travel or high-altitude destinations before making plans.

15. Can pulmonary hypertension affect my sleep?

Some people experience sleep-related breathing problems or low oxygen levels, particularly when they also have lung disease or sleep apnoea. Tell your doctor if you snore heavily, wake up gasping, or feel excessively sleepy during the day. Your doctor can decide whether sleep testing is needed.

16. Is pulmonary hypertension the same as pulmonary arterial hypertension (PAH)?

Not exactly. Pulmonary hypertension is the broad term for high blood pressure in the lung arteries. Pulmonary arterial hypertension is one specific type. Other forms may be linked to heart disease, lung disease, or blood clots. Knowing which type you have is essential because treatment differs.

17. How long can someone live with pulmonary hypertension?

There is no single answer. Life expectancy depends on the type of pulmonary hypertension, how advanced it is, heart function, other health conditions, and response to treatment. Advances in treatment have improved outcomes for many patients, making specialist care and regular follow-up especially important.

18. Which doctor should I see for pulmonary hypertension?

A pulmonologist (lung specialist) or cardiologist (heart specialist) may assess your symptoms. Confirmed or suspected pulmonary hypertension may require a specialist team with experience in the condition. Your doctor can advise whether referral to a dedicated service is appropriate.

19. When should I seek urgent medical help?

Seek emergency medical care if you develop sudden or severe breathlessness, severe or persistent chest pain, or fainting. Do not wait for a routine appointment if symptoms are severe or rapidly worsening.

20. Can I live a better life with pulmonary hypertension?

Many people can manage their condition with the right diagnosis, appropriate treatment, and regular follow-up. Your care plan may need adjustments over time, so report new symptoms and discuss any concerns with your healthcare team. Understanding your condition and knowing when to seek help are important steps towards better care.

Final Thoughts

Pulmonary hypertension can feel worrying, especially when breathlessness begins to interfere with everyday life. But you do not have to navigate it alone. Understanding your symptoms, getting the right tests, and following an individualised treatment plan can help you make informed decisions about your health.

If you have persistent breathlessness, unexplained fatigue, dizziness, or swelling in your legs, speak with a qualified healthcare professional.

The post Pulmonary Hypertension: Understanding Your Symptoms, Concerns and Treatment Options appeared first on The Chest Clinic Karachi.

While these symptoms can have several causes, they may sometimes be signs of chronic obstructive pulmonary disease (COPD), a long-term lung condition that makes breathing difficult.

COPD can affect a person’s energy, independence and quality of life. However, a diagnosis does not mean giving up the activities you enjoy. With the right treatment, medical guidance and lifestyle changes, many people with COPD can manage their symptoms and remain active.

Understanding the warning signs and knowing when to seek help are important first steps towards better breathing.

What Exactly Happens in COPD?

COPD is a chronic lung disease that restricts airflow, making it harder to breathe in and, particularly, breathe out. It includes two main conditions: chronic bronchitis, which involves inflammation and excess mucus in the airways, and emphysema, which damages the tiny air sacs in the lungs.

Smoking is a major risk factor, but it is not the only cause. Long-term exposure to air pollution, household cooking smoke, workplace dust and chemical fumes can also contribute. Some people develop COPD because of genetic factors or problems affecting lung development.

Although COPD currently has no cure, it is treatable. Early diagnosis and appropriate care can help control symptoms, reduce flare-ups and improve quality of life.

Is Your Breathlessness Trying to Tell You Something?

One of the challenges with COPD is that symptoms often develop gradually. People may start walking more slowly, avoiding stairs or taking frequent breaks without realizing that their breathing has changed.

Watch for these common warning signs:

• Breathlessness during everyday activities: Walking, climbing stairs or carrying groceries becomes increasingly difficult.
• A cough that keeps coming back: A persistent cough may be dismissed as a smoker’s cough or a seasonal problem.
• Regular mucus production: You frequently cough up phlegm, particularly in the morning.
• Wheezing or chest tightness: Breathing may feel uncomfortable or produce a whistling sound.
• Frequent chest infections: Respiratory infections occur repeatedly or take longer to recover from.
• Unusual tiredness: Everyday tasks leave you feeling exhausted because breathing requires more effort.

These symptoms do not automatically mean you have COPD. Asthma, heart conditions and other illnesses can cause similar problems.

If you experience persistent breathlessness, a long-lasting cough or regular mucus production, arrange a medical assessment. Sudden or severe breathlessness, chest pain, confusion or blue or grey lips require urgent medical attention.

Why Do Some People Develop COPD?

COPD usually develops after prolonged exposure to substances that irritate or damage the lungs.

Smoking and second-hand smoke: Cigarette smoking is a leading cause of COPD. Stopping smoking can help slow further lung damage, even after the condition has developed.

Air pollution: Outdoor pollution and indoor smoke from cooking or heating fuels can harm respiratory health, particularly when exposure continues over many years.

Workplace dust and fumes: Certain industrial environments, construction work and other occupations may expose workers to harmful airborne particles and chemicals.

Genetic factors: A rare inherited condition called alpha-1 antitrypsin deficiency can increase the risk of developing COPD.

Importantly, you do not have to be a smoker to develop COPD. Anyone with persistent respiratory symptoms or relevant exposure risks may benefit from medical evaluation.

How Can You Know If You Have COPD?

You do not need to guess whether your breathlessness is caused by COPD. A healthcare professional can assess your symptoms and determine which tests are appropriate.

The most important breathing test for confirming COPD is spirometry. During this simple test, you breathe into a device that measures how much air you can exhale and how quickly you can blow it out.

Your doctor may also review your smoking history, environmental exposures, medical history and physical examination findings. Additional investigations may be needed to assess your condition or rule out other causes of breathlessness.

If you have been avoiding physical activity because of breathing difficulties, do not simply accept it as part of getting older. Speak with your healthcare professional about whether a lung assessment or spirometry test is appropriate.

COPD Treatment: Small Steps That Can Make a Difference

Although COPD cannot currently be cured, treatment can help you breathe more comfortably, stay active and reduce the likelihood of flare-ups. Your treatment plan will depend on your symptoms, lung function and overall health.

Inhalers and medication

Prescribed inhalers can help open the airways and reduce breathing difficulties. Some patients may need additional inhaled medicines depending on their symptoms and medical history.

Using an inhaler correctly is just as important as taking the prescribed medicine. Ask your doctor, nurse or pharmacist to check your technique, and never change your medication without medical advice.

Quitting smoking

If you smoke, quitting is one of the most important steps you can take to protect your lungs. Support from healthcare professionals, counselling and suitable smoking-cessation treatments can make quitting more manageable.

Reducing exposure to second-hand smoke, air pollution and workplace irritants is also beneficial.

Staying active with pulmonary rehabilitation

When breathing becomes difficult, avoiding activity may seem like the safest option. However, becoming inactive can gradually weaken the muscles and make everyday activities even harder.

Pulmonary rehabilitation combines supervised exercise, breathing strategies and education to help people with chronic lung disease improve stamina and manage breathlessness.

Ask your healthcare professional whether pulmonary rehabilitation or an individualized exercise programme would be suitable for you.

Eating well and preventing infections

A balanced diet helps maintain strength and overall health. Some people with COPD lose weight and muscle, while others may find that excess weight makes physical activity more difficult. Individual nutritional advice can help address these concerns.

Recommended vaccinations, regular medical reviews and an individualized COPD action plan can also help patients prepare for respiratory infections and symptom flare-ups.

When is oxygen therapy needed?

Some people with advanced COPD have persistently low blood oxygen levels and may benefit from prescribed oxygen therapy. It is not required by everyone with COPD and should only be started following appropriate medical assessment.

Living With COPD Without Giving Up the Things You Love

A COPD diagnosis can feel overwhelming, especially when breathlessness begins to interfere with daily routines. But managing COPD is about more than taking medication. It is also about maintaining independence, confidence and the ability to participate in everyday life.

A few practical habits can help:

• Take your prescribed medicines as directed.
• Learn how to recognize changes in your breathing.
• Stay active within the limits recommended by your healthcare team.
• Avoid tobacco smoke and reduce exposure to other lung irritants.
• Attend follow-up appointments and ask questions about your treatment.
• Seek support if breathlessness causes anxiety or affects your mood.

Family members can also play an important role by offering practical support, encouraging appropriate activity and helping patients recognize when symptoms are getting worse.

The goal is not simply to manage a lung condition. It is to help each patient live as comfortably, independently and actively as possible.

What Is a COPD Flare-Up, and When Should You Worry?

A COPD flare-up, also known as an exacerbation, occurs when symptoms become worse than usual. You may notice increased breathlessness, more coughing, changes in mucus production or difficulty performing your normal activities.

Respiratory infections and air pollution are common triggers. Prompt medical assessment can help determine the cause and appropriate treatment.

Contact your healthcare professional if your symptoms worsen beyond their usual pattern. Severe breathlessness, chest pain, confusion or blue or grey lips require emergency care.

Frequently Asked Questions About COPD

Can COPD be cured?

There is currently no cure for COPD, but treatment can help control symptoms, improve physical function and reduce flare-ups. Early diagnosis and regular follow-up are important for managing the condition.

Can someone develop COPD without smoking?

Yes. Air pollution, household smoke, workplace exposures, genetic conditions and problems affecting lung development can contribute to COPD, even in people who have never smoked.

What are the first signs of COPD?

Early symptoms may include breathlessness during physical activity, a persistent cough, regular mucus production and reduced exercise tolerance. These symptoms should be assessed rather than dismissed as normal ageing.

Is COPD the same as asthma?

No. COPD and asthma are different respiratory conditions, although both can cause coughing, wheezing and breathlessness. Some people may have features of both, so an accurate medical assessment is important.

Can people with COPD exercise?

Yes. Appropriate physical activity can improve stamina and muscle strength. Your healthcare professional can help you choose suitable activities, and pulmonary rehabilitation may be particularly beneficial.

How long can a person live with COPD?

Life expectancy varies according to disease severity, lung function, flare-ups, other medical conditions and response to treatment. Appropriate medical care, smoking cessation and healthy daily habits can help people manage COPD and maintain their quality of life.

When should I see a doctor about breathing problems?

Seek medical advice if you have persistent breathlessness, a long-lasting cough, regular mucus production or repeated chest infections. Sudden or severe breathing difficulties require urgent medical attention.

Better Breathing Starts With the Right Care

COPD can affect how you breathe, move and experience everyday life, but you do not have to navigate the condition alone. Recognizing the warning signs, getting an accurate diagnosis and following an appropriate treatment plan can make a meaningful difference.

If walking short distances leaves you breathless or a persistent cough has become part of your daily routine, do not ignore these changes. Speak with a qualified healthcare professional to understand what may be causing your symptoms.

Understanding the possible causes of flu-like symptoms can help you know when testing may be useful, how to manage your illness and when to seek medical attention.

What Are Flu-Like Symptoms?

Flu-like symptoms describe a group of symptoms commonly associated with influenza and other respiratory infections. These may include:

• Fever or chills
• Body aches and muscle pain
• Headache
• Cough
• Sore throat
• Runny or blocked nose
• Fatigue and weakness

Influenza often begins suddenly, with fever, body aches and marked tiredness. However, not everyone with influenza develops a fever, and symptoms can vary from person to person.

What Else Can Cause Flu-Like Symptoms?

Several infections can resemble influenza, including the following.

1. Common cold

A common cold usually causes a runny or blocked nose, sneezing, sore throat and cough. Symptoms often develop gradually and tend to be milder than those of influenza, although there can be considerable overlap.

2. COVID-19

COVID-19 can cause fever, cough, sore throat, fatigue, headache and body aches. Because these symptoms overlap with influenza, you cannot reliably distinguish the two infections by symptoms alone.

3. Respiratory syncytial virus (RSV)

RSV can cause cough, nasal congestion, fever and other respiratory symptoms. It can be particularly serious in infants, older adults and people with certain chronic medical conditions.

4. Other respiratory viruses

Various viruses can cause fever, cough, sore throat and generalised body aches. Their symptoms may be almost indistinguishable from influenza without appropriate testing.

How Can I Know Whether I Have Influenza?

Your symptoms, how quickly they developed, contact with someone who is ill and the infections currently circulating in your community can help a healthcare professional assess the likelihood of influenza.

However, symptoms alone cannot always confirm influenza or distinguish it from COVID-19 and other respiratory infections.

A flu test may be recommended when the result could affect treatment or other clinical decisions. Depending on availability and the situation, testing may involve a rapid influenza test or a molecular test, such as a PCR-based test. Some tests can detect influenza and COVID-19 at the same time.

Not everyone with mild flu-like symptoms needs testing. The decision depends on the severity of illness, individual risk factors and whether the result would change management.

Who Should Be Particularly Careful?

Influenza can cause complications, including pneumonia. Certain people have a higher risk of severe illness, even if their initial symptoms seem mild.

These include:

• Adults aged 65 years and older
• Young children, particularly those under five years
• Pregnant women
• People with asthma, COPD or other chronic lung diseases
• People with heart disease, diabetes or certain other chronic conditions
• People with weakened immune systems

If you have a chronic respiratory condition, such as asthma or COPD, a respiratory infection may trigger worsening symptoms or an exacerbation. Seek medical advice promptly if you develop flu-like symptoms, especially if your breathing or usual disease control deteriorates.

What Should I Do If I Have Flu-Like Symptoms?

If your symptoms are mild, rest, drink adequate fluids and monitor your condition. Stay home while unwell, avoid close contact with vulnerable people, improve ventilation and practise good respiratory hygiene to reduce the risk of spreading infection.

Use medicines for fever or pain only as appropriate for your age and medical circumstances, following the product instructions or advice from a healthcare professional.

Do not start antibiotics on your own. Antibiotics do not treat influenza, COVID-19 or other viral infections. They are used when a bacterial infection is suspected or confirmed and treatment is indicated.

Can Influenza Be Treated?

Antiviral medicines are available for influenza. They work best when started early, generally within the first 48 hours after symptoms begin.

People at increased risk of complications, those with severe or progressive illness, and patients who require hospitalisation may benefit from antiviral treatment even when more than 48 hours have passed. Treatment decisions should be made promptly by a healthcare professional; testing should not unnecessarily delay treatment when it is clinically indicated.

Antiviral medicines for influenza do not treat COVID-19 or the common cold.

When Should I Seek Medical Attention?

Seek urgent medical care if you develop:

• Difficulty breathing or significant shortness of breath
• Persistent chest pain or pressure
• Confusion, fainting or unusual difficulty staying awake
• Severe weakness or signs of dehydration
• Symptoms that improve and then return or worsen

People with chronic lung disease should also seek prompt assessment if their breathlessness increases, wheezing worsens or their usual treatment is no longer controlling their symptoms.

Can the Flu Vaccine Prevent All Flu-Like Illnesses?

The influenza vaccine reduces the risk of influenza and its complications, but it does not protect against every respiratory virus. A vaccinated person can still develop a cold, COVID-19, RSV or another respiratory infection. Influenza can also occur after vaccination, although vaccination can reduce the risk of severe illness.

The vaccine remains an important preventive measure, particularly for people at increased risk of complications from influenza.

The Chest Clinic – Dr. Javed Husain & Associates, Karachi

At The Chest Clinic – Dr. Javed Husain & Associates, based in Karachi, patients with flu-like symptoms can be assessed for possible respiratory infections and complications, particularly when they have an underlying lung condition or worsening breathing symptoms.

If you develop a persistent cough, fever, breathlessness or worsening asthma or COPD symptoms, appropriate assessment can help determine whether further testing or treatment is needed.

Remember: Flu-like symptoms do not automatically mean you have influenza. Several respiratory infections can cause similar symptoms, so recognising warning signs and seeking timely assessment when needed are important steps towards appropriate care.

The post If I Have Flu-Like Symptoms, Do I Have Influenza? appeared first on The Chest Clinic Karachi.

The 2026 campaign theme is “Let’s Talk About Cough.” The campaign encourages people living with chronic cough to share their experiences, seek medical advice and help others understand that a persistent cough can be a significant health problem. Its central message is that chronic cough can be a disease in its own right, not just a symptom of another condition.

What Is Chronic Cough?

In adults, a cough lasting more than eight weeks is generally considered chronic. In children, a cough lasting more than four weeks warrants assessment for chronic cough.

Unlike a short-lived cough caused by a common cold, chronic cough may continue for months or even years. It can be dry or produce phlegm, and it may occur throughout the day or become particularly troublesome at night.

A persistent cough should not simply be dismissed as an allergy, a throat problem or a lingering infection without considering other possible causes.

Why Is the Theme “Let’s Talk About Cough” Important?

People living with chronic cough often face difficulties that others may not recognise. Frequent coughing can interrupt conversations, disturb sleep, affect work and make social situations uncomfortable. Some people avoid public places because they feel embarrassed or worry that others may assume they have a contagious illness.

Chronic cough can also cause exhaustion, chest discomfort, headaches, urinary leakage and, in severe cases, dizziness or fainting.

The theme “Let’s Talk About Cough” highlights the need to listen to patients, acknowledge the effect of persistent coughing on their quality of life and improve awareness among the public and healthcare professionals.

What Causes a Chronic Cough?

Chronic cough can have several causes, and more than one condition may contribute to the same patient’s symptoms.

• Asthma: Some patients experience cough as their main symptom, even without obvious wheezing.
• Allergic rhinitis and post-nasal drip: Nasal inflammation and mucus draining into the throat may trigger repeated coughing.
• Acid reflux: Reflux can contribute to persistent cough, sometimes without typical heartburn.
• Chronic lung diseases: COPD, bronchiectasis and interstitial lung diseases, including pulmonary fibrosis, can cause chronic cough.
• Tuberculosis (TB): In Pakistan, TB is an important consideration, particularly when a persistent cough is accompanied by weight loss, fever, night sweats or blood in the sputum.
• Smoking and environmental irritants: Tobacco smoke, dust, air pollution and occupational exposures can irritate the airways.
• Medications: Certain medicines, including ACE inhibitors used to treat high blood pressure, may cause a persistent dry cough.

Sometimes, the cough continues even after an underlying condition has been treated. In other cases, no clear cause can be identified despite appropriate investigations. These situations may require specialist assessment.

When Should You Seek Medical Advice?

Adults should arrange medical assessment if a cough lasts longer than eight weeks, repeatedly returns or fails to improve as expected. Earlier evaluation may be necessary if symptoms are worsening or accompanied by other concerning signs.

Seek prompt medical attention for coughing up blood, unexplained weight loss, persistent fever or night sweats. Severe breathlessness or significant chest pain requires urgent assessment.

How Is Chronic Cough Diagnosed and Treated?

The first step is to understand the nature of the cough, when it started, what triggers it and whether other symptoms are present. The clinician may review medication use, smoking history, allergies, occupational exposures and previous respiratory illnesses.

Depending on the clinical findings, investigations may include a chest X-ray, spirometry, sputum testing or other targeted tests.

Treatment depends on the underlying cause. Asthma, nasal disease, reflux, infections and chronic lung conditions require different management approaches. If coughing persists despite appropriate treatment, the diagnosis and treatment plan may need to be reassessed.

Repeatedly using cough syrups without identifying the cause may not resolve a chronic cough and can delay appropriate care.

World Chronic Cough Day 2026: Let’s Start the Conversation

This World Chronic Cough Day, the message is simple: let’s talk about cough, take persistent symptoms seriously and listen to the people living with them.

Fluid around the lungs is medically known as a pleural effusion. It occurs when excess fluid collects in the space between the lung and the chest wall. This can happen because of several medical conditions, including pneumonia, tuberculosis (TB), heart failure, and certain cancers.

The important thing to understand is that fluid around the lungs is not a disease on its own. It is usually a sign of an underlying problem that needs to be identified.

What is a pleural effusion?

The lungs are covered by a thin membrane called the pleura. A second layer lines the inside of the chest wall. A small amount of fluid normally exists between these layers, allowing them to move smoothly during breathing.

When too much fluid accumulates in this space, it is called a pleural effusion.

As the fluid increases, it can press against the lung and prevent it from expanding fully, leading to breathlessness and chest discomfort.

What causes fluid around the lungs?

The causes of pleural effusion vary, and identifying the cause is essential for choosing the right treatment.

1. Pneumonia and other infections

Pneumonia can cause inflammation around the lungs, allowing fluid to accumulate in the pleural space. This is called a parapneumonic effusion.

In some cases, the fluid becomes infected and develops into a collection of pus, known as an empyema. This usually requires antibiotics and may also require drainage.

2. Tuberculosis (TB)

Tuberculosis is an important cause of pleural effusion in countries where TB is common, including Pakistan.

TB-related pleural effusion may cause chest pain, cough, fever, night sweats, or weight loss. However, symptoms can vary, and some patients may not have all these features.

Further investigations are often needed to determine whether TB is responsible.

3. Heart failure

Heart failure can cause fluid to accumulate around the lungs, sometimes affecting both sides.

Patients may also experience breathlessness while lying flat, swelling of the legs, or difficulty breathing during physical activity.

Treatment focuses on managing the heart condition and reducing excess fluid.

4. Cancer

Certain cancers, including lung cancer, breast cancer, and lymphoma, can cause pleural effusion.

Fluid around the lungs does not automatically mean cancer. However, an unexplained effusion, particularly one that persists or returns, may require further investigation to exclude a serious underlying cause.

5. Kidney or liver disease

Certain kidney and liver conditions can cause excess fluid to accumulate in the body, including around the lungs.

The treatment depends on the underlying condition and the amount of fluid present.

6. Other causes

Pleural effusion may also occur with blood clots in the lungs, autoimmune diseases, chest injuries, and some other medical conditions.

This is why the cause should not be assumed from an X-ray alone.

What are the symptoms of fluid around the lungs?

Some patients have no noticeable symptoms, and the fluid is discovered during imaging performed for another reason.

When symptoms occur, they may include:

• Shortness of breath, particularly during activity
• Chest pain that worsens with deep breathing or coughing
• Persistent cough
• Difficulty breathing when lying flat
• Reduced ability to walk or perform everyday activities
• Fever or other symptoms related to the underlying illness

The severity of symptoms depends on the amount of fluid, how quickly it develops, and the underlying cause.

How is pleural effusion diagnosed?

A doctor may recommend several investigations depending on the patient’s symptoms and medical history.

Chest X-ray: Often identifies fluid around the lungs and provides an initial assessment.

Chest ultrasound: Helps determine the amount and location of fluid and can guide drainage when required.

CT scan of the chest: May provide more detailed information about the lungs, pleura, and surrounding structures.

Pleural fluid analysis: If fluid needs to be sampled, it can be examined for signs of infection, inflammation, cancer, and other possible causes.

Blood tests and other investigations: These may help identify conditions such as heart failure, kidney disease, infection, or TB.

Not every patient requires every test. The investigation plan depends on the clinical findings.

Does fluid around the lungs need to be removed?

Not every pleural effusion needs drainage.

Treatment depends on the cause, the amount of fluid, the patient’s symptoms, and whether the fluid is infected or requires analysis.

• Small effusions: Some can be managed by treating the underlying condition and monitoring the patient.
• Effusions causing significant breathlessness: Drainage may be recommended to relieve symptoms.
• Suspected infection or unexplained fluid: Sampling the fluid may help establish the diagnosis.
• Infected fluid or empyema: Antibiotics and drainage are often necessary.
• Fluid caused by heart failure: Treatment usually focuses on managing heart failure and excess fluid.

Removing the fluid may improve breathing, but it does not necessarily treat the condition that caused it. That underlying problem must also be addressed.

Can fluid around the lungs come back?

Yes. Pleural effusion can recur, particularly when the underlying cause remains active.

For example, fluid may return if heart failure is not adequately controlled or if the condition responsible for a persistent pleural effusion has not been treated.

If fluid repeatedly accumulates, further investigation may be necessary. Depending on the cause, treatment options can include repeated drainage, a longer-term drainage catheter, or a procedure to reduce fluid recurrence.

The appropriate approach varies from patient to patient.

Is fluid around the lungs dangerous?

The seriousness of a pleural effusion depends on its cause, size, and effect on breathing.

A small effusion may cause few symptoms, whereas a large effusion can significantly restrict lung expansion. An infected effusion can also become serious if not treated appropriately.

Seek urgent medical attention if you develop severe or rapidly worsening breathlessness, severe chest pain, confusion, or bluish lips.

Persistent symptoms, unexplained weight loss, coughing up blood, or an unexplained or recurrent pleural effusion also warrant prompt medical evaluation.

If you have been diagnosed with pneumonia but do not have a fever, this does not necessarily mean the diagnosis is wrong. Pneumonia can affect people differently depending on their age, immune system, underlying health conditions, and the type of infection.

Can you have pneumonia without a fever?

Yes, pneumonia can occur without fever.

Fever is the body’s response to infection, but not everyone develops it. Some people with pneumonia may instead experience:

• Cough, with or without phlegm
• Shortness of breath
• Chest discomfort or pain
• Weakness or unusual tiredness
• Faster breathing
• Reduced exercise tolerance
• Loss of appetite
• Confusion or drowsiness, particularly in older adults

Therefore, the absence of fever does not rule out pneumonia.

Why can pneumonia occur without fever?

There are several reasons why someone with pneumonia may not develop a noticeable fever.

Older adults

Older people may have a less obvious immune response to infection. Instead of fever, they may develop weakness, confusion, reduced appetite, or worsening breathing.

A weakened immune system

People taking certain medicines or living with conditions that affect the immune system may not develop a strong fever even when an infection is present.

Antibiotics taken before diagnosis

If antibiotics have already been started, the fever may improve while inflammation or infection in the lungs is still present.

Certain types of pneumonia

Some infections can produce different symptoms and may not always cause a significant fever.

Chronic medical conditions

People with conditions such as COPD, asthma, diabetes, heart disease, or other chronic illnesses may experience pneumonia differently from otherwise healthy individuals.

How is pneumonia diagnosed if there is no fever?

Doctors do not diagnose pneumonia based on fever alone.

The diagnosis may involve a combination of:

• Symptoms and medical history
• Examination of the chest and breathing
• Oxygen saturation measurement
• Chest X-ray or other imaging when appropriate
• Blood tests in selected patients
• Sputum or other microbiological testing in certain situations

A chest X-ray may show changes consistent with pneumonia even when the patient has no fever.

This is why someone can be diagnosed with pneumonia despite having a normal temperature.

Is pneumonia without fever less serious?

Not necessarily.

The severity of pneumonia is not determined simply by whether a patient has fever. A person without fever can still have significant infection or low oxygen levels.

Pay particular attention to symptoms such as:

• Increasing breathlessness
• Low oxygen saturation
• Rapid breathing
• Chest pain
• Severe weakness
• Confusion or unusual sleepiness
• Bluish lips or fingertips

These symptoms require prompt medical assessment.

Can pneumonia cause only a cough?

Sometimes, especially in milder cases, cough may be one of the main symptoms. However, pneumonia can also cause breathlessness, fatigue, chest discomfort, and reduced oxygen levels.

A persistent or worsening cough should not automatically be assumed to be pneumonia. Other conditions, including asthma, COPD, bronchitis, post-nasal drainage, acid reflux, and other respiratory infections, can also cause cough.

A proper evaluation helps determine the cause.

What should you do if you have pneumonia but no fever?

If a doctor has diagnosed pneumonia, follow the recommended treatment and monitor your symptoms rather than using fever as the main indicator of improvement.

You should pay attention to:

• Whether your breathing is improving
• Whether your cough is getting better or worse
• Your energy and ability to perform normal activities
• Your oxygen saturation, if you have been advised to monitor it
• Whether new symptoms develop

Recovery can take time, and the cough and tiredness may persist even after the infection begins to improve.

If symptoms are worsening despite treatment, you should be reassessed.

When should you seek urgent medical attention?

Seek urgent medical care if pneumonia is associated with significant difficulty breathing, worsening oxygen levels, confusion, severe chest pain, marked drowsiness, or a rapid deterioration in your condition.

People who are older or have chronic lung disease, heart disease, diabetes, or a weakened immune system may require closer monitoring.

Flu can affect the lungs and may trigger worsening of an existing lung condition. For people with asthma and chronic lung disease, influenza is associated with a higher risk of serious complications, including hospitalization.

This is why the influenza vaccine, commonly called the flu vaccine, is an important part of protecting your lung health.

Why Is Flu More Concerning If You Have Lung Disease?

When you already have a lung condition, your breathing system may have less reserve to cope with an additional respiratory infection.

Influenza can cause inflammation in the respiratory tract and may worsen symptoms such as:

• Cough
• Wheezing
• Shortness of breath
• Chest tightness
• Increased phlegm

In people with asthma, flu can trigger an asthma attack. In people with COPD, respiratory infections can contribute to a flare-up, sometimes requiring additional treatment or hospitalization.

Flu can also cause pneumonia, including pneumonia caused by the influenza virus itself or by a secondary bacterial infection.

Who With Lung Disease Should Consider a Flu Vaccine?

Influenza vaccination is particularly important for people with chronic lung disease, including conditions such as:

• Asthma
• COPD
• Chronic bronchitis
• Emphysema
• Cystic fibrosis
• Other chronic respiratory conditions

People with asthma can be at increased risk of serious flu complications even when their asthma is mild or well controlled.

Current CDC guidance also identifies people with chronic pulmonary conditions, including asthma, as a group at increased risk from influenza complications.

Can the Flu Vaccine Prevent a Lung Flare-Up?

It can help reduce the risk of influenza and its complications, but it is important to understand what the vaccine can and cannot do.

For example, if you have COPD, influenza can contribute to a worsening of your symptoms or a COPD exacerbation. Vaccination can reduce the risk of influenza-related illness and may reduce the risk of exacerbations associated with influenza.

However, the vaccine cannot prevent every cause of a respiratory infection.

Many different viruses can cause cough, fever, sore throat, congestion, and other symptoms. A person may therefore become sick after receiving a flu vaccine because the illness is caused by another virus rather than influenza.

Can I Still Get Flu After the Vaccine?

Yes.

The influenza vaccine is not a guarantee that you will never get influenza. Vaccine protection can vary from season to season depending on several factors, including the influenza viruses circulating during that season and how well the vaccine matches them.

However, vaccination remains an important way to reduce the risk of influenza and serious outcomes from flu. CDC recommends seasonal influenza vaccination as the most important step for reducing the risk of flu and its complications.

So, getting the flu vaccine does not mean you will never have a cough or respiratory infection during the year. It means you are taking an important step to protect yourself against influenza.

Does the Flu Vaccine Cause Flu?

The flu vaccine does not give you influenza.

Some people may experience mild soreness at the injection site, tiredness, or other short-lived reactions after vaccination. These are not the same as having influenza.

If you develop significant respiratory symptoms after vaccination, the illness may be caused by another infection, or you may have been exposed to influenza before the vaccine had time to provide protection.

Is the Flu Vaccine Needed Every Year?

Yes, seasonal influenza vaccination is generally given every year.

Influenza viruses change over time, and the composition of seasonal flu vaccines is updated when needed. For the 2026–2027 season, for example, all three components of the U.S. seasonal influenza vaccines were updated compared with the previous season.

The appropriate timing of vaccination can vary depending on the influenza season and the country or region where you live.

What If I Already Have a Lung Condition?

Having a chronic lung condition is not a reason to avoid the flu vaccine in most cases.

In fact, people with chronic lung disease are among those for whom influenza vaccination is particularly important because of their increased risk of complications.

Your usual lung treatment should also continue as prescribed. The flu vaccine does not replace your inhalers, oxygen therapy, pulmonary rehabilitation, or other treatment for your underlying lung condition.

Protecting Your Lungs From Flu

If you have a chronic lung condition, preventing respiratory infections should be part of your overall lung-care plan.

Along with seasonal influenza vaccination, it is important to follow your prescribed lung treatment, avoid smoking and second-hand smoke, practice good hand hygiene, and seek medical attention if your breathing suddenly becomes worse.

If you develop flu-like symptoms and have a chronic lung condition, seek medical advice promptly. Antiviral medicines can be useful for people at higher risk of serious influenza complications and are most effective when started early.

But what exactly does it do? Can it improve your breathing? And does everyone with a lung disease need to use one?

What Is an Incentive Spirometer?

An incentive spirometer is a simple breathing device that encourages you to take a slow, deep breath and helps you see how well you are breathing in.

Unlike a regular spirometry test, which is used to assess lung function and help diagnose conditions such as asthma or COPD, an incentive spirometer is primarily a breathing exercise tool.

The aim is to encourage deeper breaths and better expansion of the lungs.

Why Is Deep Breathing Important?

When a person is unwell, in pain, very weak, or spending a lot of time in bed, breathing can become shallower than normal. Parts of the lungs may not expand fully.

This can contribute to a condition called atelectasis, in which small areas of the lung become partially collapsed or poorly aerated.

Deep breathing exercises can help encourage the lungs to expand. An incentive spirometer provides visual feedback, which can make it easier for some patients to perform these exercises correctly and regularly.

When Can an Incentive Spirometer Be Helpful?

An incentive spirometer may be recommended in selected situations, particularly when there is a risk of reduced lung expansion.

It may be considered:

• After chest or other major surgery
• During recovery when a patient is spending prolonged periods in bed
• When pain or weakness makes deep breathing difficult
• In some patients with conditions that affect respiratory muscle strength
• When there is concern about reduced lung expansion or atelectasis

It may also be used during recovery from certain lung illnesses, including pneumonia, depending on the patient’s condition and the treating team’s advice.

Does Everyone with a Lung Disease Need an Incentive Spirometer?

No.

Having asthma, COPD, pulmonary fibrosis, bronchiectasis, pneumonia, or another lung condition does not automatically mean that you need an incentive spirometer.

An incentive spirometer does not treat the underlying cause of most lung diseases. For example, it does not replace asthma inhalers, COPD treatment, antibiotics when they are indicated, oxygen therapy when prescribed, or other disease-specific treatment.

Its role is mainly to encourage deep breathing and lung expansion when this is appropriate.

For patients with chronic respiratory diseases, treatment should be based on the specific lung condition and the patient’s symptoms, lung function, oxygen levels, physical ability, and overall health.

Is Incentive Spirometry Better Than Deep Breathing Exercises?

Not necessarily.

The incentive spirometer essentially gives the patient a visual target while performing a deep breath. Evidence suggests that deep breathing exercises can provide similar benefits in situations where incentive spirometry is used.

This is why an incentive spirometer should generally be considered an adjunct to a broader breathing and recovery program, rather than a treatment that works on its own.

After surgery, for example, clinical guidance has recommended combining breathing exercises with appropriate coughing techniques, early movement, and good pain control rather than relying on incentive spirometry alone.

How Should You Use an Incentive Spirometer?

If your doctor or respiratory therapist has recommended one, you will usually be asked to:

1. Sit upright.
2. Place your lips firmly around the mouthpiece.
3. Breathe out normally.
4. Slowly breathe in through the mouthpiece.
5. Try to reach the target indicated on the device.
6. Hold the breath briefly, as instructed.
7. Remove the mouthpiece and breathe normally.

The exact number of breaths and how often you should use the device should be based on the instructions given to you.

Do not try to force yourself to reach an unnecessarily high number on the device. The goal is to perform slow, controlled deep breaths, not to compete with a particular reading.

Can It Improve Lung Function?

This is where expectations are important.

An incentive spirometer can help a patient practice deeper breathing, but it is not a general lung-strengthening treatment and should not be expected to reverse chronic lung disease.

Evidence for routine incentive spirometry, particularly after surgery, has been inconsistent. Current guidance does not support using it routinely on its own to prevent postoperative lung complications.

Its usefulness may depend on why it is being prescribed, the patient’s condition, and whether it is being used correctly as part of an appropriate respiratory care plan.

When Should You Stop and Seek Medical Advice?

Some people may feel light-headed if they take repeated deep breaths. If this happens, stop using the device, breathe normally, and recover before continuing.

If you develop significant or worsening shortness of breath, chest pain, fever, or a noticeable deterioration in your breathing, you should seek medical assessment rather than simply increasing your use of the incentive spirometer.

Beta blockers are used for several different conditions. They may be prescribed for heart problems or high blood pressure, but they can also be used for irregular heart rhythms, migraine prevention, anxiety symptoms, overactive thyroid, certain tremors and other medical conditions.

Because some beta blockers can affect the airways and may reduce the effect of certain asthma medicines, people with asthma need careful consideration when taking them. However, having asthma does not automatically mean that you cannot take a beta blocker. In some situations, a suitable beta blocker can be used under medical supervision.

Why can beta blockers be a concern in asthma?

Some beta blockers can affect the receptors in the airways that help asthma medicines open the breathing passages.

This is particularly important with non-selective beta blockers, which can block the beta receptors involved in airway relaxation.

As a result, they can sometimes cause wheezing or bronchospasm and may reduce the effect of beta-agonist medicines, such as salbutamol.

This does not mean that every person with asthma cannot take a beta blocker.

Can I use my asthma inhalers while taking a beta blocker?

Yes, in many cases.

If you have been prescribed a regular maintenance inhaler, you should generally continue using it as prescribed. Maintenance inhalers are important for keeping asthma under control and reducing the risk of asthma attacks.

Some maintenance inhalers contain medicines that reduce inflammation, while others also contain a long-acting medicine that helps keep the airways open.

A beta blocker does not cancel the anti-inflammatory effect of an inhaled corticosteroid. However, if the maintenance inhaler contains a long-acting beta-agonist, a beta blocker can potentially reduce some of its airway-opening effect.

This is one reason your doctor should know about all the medicines you are taking.

What about my rescue inhaler?

Rescue or reliever inhalers, such as salbutamol, work quickly to relax the airway muscles during asthma symptoms.

Because salbutamol is a beta-agonist, some beta blockers can reduce its effect.

If you notice that your usual reliever inhaler is not working as well as it normally does, or your wheezing and breathlessness are increasing after starting a beta blocker, contact your doctor.

Do not simply stop your beta blocker yourself.

So, can I take a beta blocker if I have asthma?

Sometimes, yes.

The decision depends on:

• Why you need the beta blocker
• Which beta blocker you are taking
• The dose
• How well your asthma is controlled
• Your previous response to beta blockers
• Which asthma medicines you are using

When a beta blocker is important for the heart, a cardio selective beta blocker may be considered in appropriate patients under medical supervision. GINA states that asthma should not be regarded as an absolute contraindication to cardio selective beta blockers when they are indicated for important cardiovascular conditions.

Should I stop my beta blocker?

No. Do not stop it on your own.

Suddenly stopping some beta blockers can cause problems, particularly when they have been prescribed for significant heart disease or abnormal heart rhythms and other conditions.

If you have asthma and need a beta blocker, your doctor can decide whether the medicine is appropriate, whether a different beta blocker would be better, or whether your treatment needs closer monitoring.

Likewise, do not stop your regular asthma maintenance inhaler because you are taking a beta blocker. Keeping asthma well controlled is an important part of reducing the risk of breathing problems. GINA recommends continued use of appropriate inhaled corticosteroid-containing treatment for asthma.

The important message

Having asthma does not automatically mean you cannot take a beta blocker.

Some beta blockers can worsen bronchospasm or reduce the response to beta-agonist medicines such as salbutamol. However, when a beta blocker is medically important, particularly for a heart condition, it may still be possible to use one safely with appropriate medical assessment and monitoring.

The important thing is not to stop either your beta blocker or your asthma treatment on your own.

Your heart and lung medicines should be considered together so that you receive the treatment you need for both conditions.

Many patients wonder why a breathing test is necessary when the surgery may have nothing to do with the lungs.

The reason is simple: anesthesia, surgery, pain medicines, reduced mobility, and the surgical procedure itself can place additional demands on the respiratory system. Knowing how well your lungs are functioning before surgery can help your medical team identify potential risks and, when necessary, improve your lung condition before the operation.

What Are PFTs and Spirometry?

Pulmonary function tests (PFTs) are a group of tests used to assess how well the lungs are working. Spirometry is one of the most commonly performed pulmonary function tests.

Spirometry measures how much air you can breathe out and how quickly you can blow the air out. It can help identify airflow obstruction and assess conditions such as asthma and COPD.

Depending on the patient’s condition, a more complete PFT may also include measurements of lung volumes and diffusing capacity (DLCO), which provides information about how effectively oxygen passes from the lungs into the blood.

Why Is Spirometry Important Before Surgery?

The purpose of preoperative lung testing is not simply to produce a number.

It helps the doctor understand your respiratory reserve—in other words, how much breathing capacity your lungs have before they are exposed to the additional stress of surgery.

This information can be particularly useful when a patient already has a known lung disorder or significant respiratory symptoms.

A preoperative pulmonary assessment may help doctors:

• Identify previously unrecognized airflow limitation
• Assess the severity of an existing lung condition
• Determine whether the lung disease is adequately controlled
• Identify patients who may need optimization before surgery
• Help estimate the risk of postoperative breathing problems
• Decide whether additional pulmonary testing is necessary
• Assist the anesthesia and surgical teams in planning perioperative care

Preoperative pulmonary assessment is particularly relevant in patients with established respiratory disease and those undergoing thoracic or upper abdominal surgery.

Does Every Patient Need Spirometry Before Surgery?

No.

This is an important point.

Spirometry is not automatically required before every surgical procedure simply because a patient is having an operation.

The need for PFTs depends on several factors, including:

• The type and extent of surgery
• Whether the operation involves the chest or upper abdomen
• Existing lung disease
• Shortness of breath or exercise limitation
• Smoking history
• Abnormal findings on examination or previous investigations
• The patient’s overall health and functional capacity
• Whether the results are likely to change management

A careful medical history and physical examination remain central to preoperative risk assessment. Additional tests should be requested when they provide useful information for the individual patient.

Which Patients With Lung Disease May Benefit From PFTs Before Surgery?

Your doctor may consider pulmonary function testing if you have conditions such as:

COPD or emphysema

Patients with COPD may have reduced airflow and limited respiratory reserve. Spirometry can help determine the degree of airflow limitation and whether the condition is adequately controlled before surgery.

Asthma

If asthma is poorly controlled, surgery may be more difficult from a respiratory standpoint. Assessing lung function can help identify airflow limitation and may assist in optimizing treatment before an elective procedure.

Pulmonary fibrosis or interstitial lung disease

Patients with interstitial lung disease may have abnormalities in lung volumes and gas transfer. A complete PFT, including DLCO when appropriate, can provide additional information about pulmonary reserve.

Bronchiectasis

Patients with bronchiectasis may have chronic cough, sputum production, recurrent infections, and abnormal lung function. Preoperative assessment can help determine whether the respiratory condition is stable before surgery.

Previous major lung surgery or significant lung damage

If part of the lung has previously been removed or there is significant structural lung disease, pulmonary function testing can provide useful information about the remaining lung function.

What If the PFT Is Abnormal?

An abnormal PFT does not automatically mean that surgery cannot be performed.

This is a common concern among patients.

Instead, an abnormal result may prompt the doctor to look more closely at the cause and determine whether the patient’s lung condition can be optimized before surgery.

Depending on the situation, this may involve:

• Adjusting inhaler treatment
• Treating an active respiratory infection
• Improving asthma or COPD control
• Assessing oxygen requirements
• Encouraging smoking cessation
• Assessing exercise capacity
• Considering pulmonary rehabilitation
• Obtaining additional investigations when indicated

The goal is not simply to decide whether a patient can or cannot have surgery. The goal is to understand and reduce avoidable respiratory risks wherever possible.

Is Spirometry Enough?

Not always.

Spirometry provides important information about airflow, but some patients require a more complete assessment.

Depending on the clinical situation, a doctor may consider:

Full pulmonary function testing: This may include lung volumes and DLCO.

Six-minute walk test: This can provide information about exercise tolerance and oxygenation.

Cardiopulmonary exercise testing: In selected patients, particularly when major lung surgery is being considered, more detailed exercise testing may be required.

Chest imaging: Previous CT scans or chest X-rays may provide important information about the underlying lung disease.

The appropriate tests depend on the patient’s condition and the planned operation.

PFT Before Lung Surgery Is Especially Important

Patients who are being considered for lung resection, such as surgery for lung cancer, require particularly careful assessment of their remaining lung function.

Spirometry and DLCO are important components of this evaluation. In patients with reduced lung function, doctors may calculate predicted postoperative lung function and, when necessary, perform additional exercise testing to better understand the risk of surgery.

This assessment helps the surgical team determine whether the patient has sufficient respiratory reserve for the planned procedure and whether an alternative treatment approach should be considered.

Can PFT Help Make Surgery Safer?

A PFT itself does not make surgery safer.

Its value is in providing information that can influence medical decision-making.

For example, if testing reveals poorly controlled obstructive lung disease, there may be an opportunity to optimize treatment before an elective operation.

Similarly, if testing suggests significantly reduced pulmonary reserve, the medical team may decide that additional assessment or specific perioperative precautions are appropriate.

Preoperative evaluation provides an opportunity to identify underlying disease, optimize medical conditions, and develop an individualized plan for the patient’s surgery and anesthesia.

What Should Patients Tell Their Doctor Before PFT?

Before pulmonary function testing, tell the doctor or testing staff about:

• Your current lung disease
• All inhalers and respiratory medications you use
• Recent chest infections
• Recent surgery or significant medical problems
• Oxygen use
• Smoking history
• Any significant breathlessness or chest symptoms

You may also be given specific instructions about whether certain inhalers or medications should be withheld before testing. Do not stop a prescribed medication unless your doctor or testing center specifically instructs you to do so.
