Information about COPD

About

COPD is a chronic inflammatory disease of the lungs, in which the airways become blocked, causing cough with mucus, wheezing, and shortness of breath.

Causes

The causes of COPD are not fully understood. However, long-term exposure to lung irritants is known to damage the lungs and the airways.

Symptoms

Some people may also experience exacerbations, or episodes of sudden disease worsening, that may persist for several days.
