The doctor who specialises in pulmonology is called a pulmonologist. Pulmonology is a branch of medicine related to the study of the respiratory system and diagnosing and treating any respiratory disorders. Pulmonologists are also called lung specialists and treat respiratory disorders associated with infections, structural deformities, inflammations, tumours, or autoimmune diseases (such as allergies) of the lungs and airways.
Pulmonologists may not perform surgeries unless necessary; their usual treatment approach involves prescribing appropriate medication and other therapies. In order to correctly diagnose your condition, they may ask you to undergo several tests such as the following:
a. Chest fluoroscopy or ultrasound to check the functioning of lungs
b. Pulse oximetry to check blood oxygen concentration levels
c. Sputum culture to detect infection due to bacteria or fungi in lungs
d. Bronchoscopy to determine issues in the throat, trachea, or the lower airways
When you go for a pulmonologist consultation with these test reports, the doctor may recommend procedures, such as thoracentesis, to remove fluid from the lungs depending on your condition.
A general physician might recommend you to visit a chest specialist (pulmonologist consultant) for special care. Both these doctors, your general physician and pulmonologist, may also end up working together on your case if need be.
