Chronic obstructive pulmonary disease (COPD) is a group of conditions that affect your lungs.

COPD causes difficulty breathing, with symptoms that may progress over time. About 16 million Americans have received a COPD diagnosis, and it is estimated that millions more are unaware that they have the condition.
