Information about COPD


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


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


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