Pulmonology is a medical specialty that focuses on the diagnosis, treatment, and management of respiratory and lung diseases. A pulmonologist, also known as a respiratory disease specialist, has expertise in conditions such as asthma, chronic obstructive pulmonary disease (COPD), lung cancer, pulmonary fibrosis, pulmonary hypertension, tuberculosis, and other respiratory conditions.

Pulmonologists receive specialized training in the physiology of respiration, anatomy, and pathophysiology of lung diseases. They utilize diagnostic tools such as spirometry, bronchoscopy, imaging tests, and blood gas analysis to diagnose and treat respiratory conditions.
