What is COPD?

COPD, or chronic obstructive pulmonary disease, is a progressive disease that makes it difficult to breathe.

COPD can cause coughing that produces large amounts of mucus, wheezing, shortness of breath, chest tightness, and other symptoms.

Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke.
Long-term exposure to other lung irritants—such as air pollution, chemical fumes, or dust—also may contribute to COPD.

Most people who have COPD have both emphysema and chronic bronchitis.
