What is COPD?

COPD stands for Chronic Obstructive Pulmonary Disease, a chronic lung disease that makes it difficult to breathe. It’s usually caused by long-term exposure to irritants that damage the lungs, such as cigarette smoke, air pollution, or chemical fumes. The two most common forms of COPD are emphysema and chronic bronchitis.

Emphysema is a condition where the air sacs in the lungs are damaged, causing them to lose their elasticity and making it difficult to exhale.

Chronic bronchitis is a condition where the bronchial tubes become inflamed and produce excess mucus, leading to coughing and difficulty breathing.
