Who Is a Pulmonologist?

A pulmonologist, also known as a chest physician, is a medical specialist trained in diagnosing and treating diseases of the lungs, airways, and respiratory system. They manage conditions affecting breathing, oxygen levels, and overall lung health. Pulmonologists are also trained to interpret chest imaging, perform lung function tests, and manage complex respiratory illnesses.

Common Diseases Treated by a Pulmonologist

Pulmonologists commonly treat:

  • Asthma
  • Chronic Obstructive Pulmonary Disease (COPD)
  • Chronic bronchitis
  • Pneumonia
  • Tuberculosis
  • Bronchiectasis
  • Interstitial lung disease (ILD)
  • Lung fibrosis
  • Pleural effusion
  • Sleep apnea
  • Lung nodules and suspected lung cancer

They also manage autoimmune-related lung conditions such as:

  • Rheumatoid arthritis–associated lung disease
  • Lupus-related lung involvement
  • Sarcoidosis
  • Vasculitis affecting the lungs
