Understanding COPD | Duke Health

Chronic obstructive pulmonary disease (COPD) is a leading cause of death in the U.S. People with the disease can have chronic bronchitis, emphysema, or both, but in its early stages, COPD may go undetected. That's why it's important to visit your doctor regularly and to stop smoking -- by far, the most common cause of COPD.

Here, Duke pulmonologist Lingye Chen, MD discusses what COPD is, symptoms to look for, how COPD is diagnosed, and how to manage the condition.
