Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory
lung disease that causes obstructed airflow from the lungs, making it
hard to breathe. It includes chronic bronchitis and emphysema.
The disease is increasingly common and is the third leading cause of death
in the U.S. The good news is COPD is often preventable and treatable.
With proper management, most people with COPD can achieve good symptom
control and quality of life.
