What is COPD?

Chronic obstructive pulmonary disease, or COPD, is a lung disease in which the lung is damaged, making it hard to breathe. In COPD, the airways that carry air in and out of your lungs become partially blocked, making it difficult to get air in and out. COPD is a major cause of death and illness throughout the world. It is the 4th leading cause of death in the U.S. and the world.
