Your Health: COPD (Chronic Obstructive Pulmonary Disease)
Chronic obstructive pulmonary disease, or COPD, is the third-leading cause of death in the United State. There are two main types, chronic bronchitis and emphysema, which cause blockage of the airflow in the lungs and breathing-related problems. Cigarette smoking is the leading cause of this disease but 20 percent of cases occur in non-smokers. University of Maryland pulmonologist Dr. Robert Reed discusses how COPD is diagnosed and treated and ways to help slow down progression of the disease.
