How Do Allergies Cause Asthma?
An allergic response occurs when the body’s immune system proteins also called antibodies mistakenly identify a harmless substance, such as tree pollen or animal dander, and considers it as an invader (allergen). This misrecognition causes an allergic reaction to result. Antibodies formed by the body bind to the allergen in an effort to shield your body from the chemical.
Your immune system’s production of chemicals causes allergy symptoms and signs like runny nose, itchy eyes, and skin rashes. Individuals may experience a similar reaction in their lungs and breathing channels or airways, which causes inflammation and tightening of the airways resulting in symptoms of asthma. These symptoms include cough, chest tightness, wheezing and shortness of breath.
What are common Allergens causing Asthma?
The common allergens found in the environment that causes symptoms of allergies and asthma include Pollen, Animal dander, Dust mite, Smoke and pollution amongst others. Certain foods ( e.g Peanuts, shell fish etc.) can trigger an allergic response in a person ranging from mild rash to a severe allergic reaction called “Anaphylaxis”
