What is Chronic Obstructive Pulmonary Disease (COPD)?
Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease characterized by long-term respiratory symptoms and airflow limitation. COPD primarily encompasses two conditions: chronic bronchitis and emphysema. These conditions cause inflammation and damage to the airways and air sacs in the lungs, leading to breathing difficulties, coughing, and mucus production. The disease is often caused by long-term exposure to harmful substances like cigarette smoke, air pollution, and occupational chemicals.
