What is Chronic Obstructive Pulmonary Disease (COPD)?
Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung condition characterized by persistent respiratory symptoms and airflow limitation. It encompasses diseases such as emphysema and chronic bronchitis. COPD is primarily caused by long-term exposure to irritants, most notably cigarette smoke, which lead to inflammation and damage to the airways and alveoli.
