Chronic obstructive pulmonary disease (COPD) is a group of lung diseases that block airflow and make it difficult to breathe. COPD includes conditions such as emphysema and chronic bronchitis.
Asthma is a chronic inflammatory disorder of the airways that can cause wheezing, shortness of breath, chest tightness, and coughing.
Pulmonary fibrosis is a lung condition that causes thickening and scarring of the lung tissue, making it difficult for the lungs to function properly. This can cause shortness of breath, a dry cough, and fatigue.
Note: This is not an exhaustive list, Pulmonologists also treat lung cancer, lung infections, pleural effusion, sleep apnea, sarcoidosis and other lung related conditions.
