Emphysema is a long-term (chronic), irreversible lung disease that occurs when the tiny air sacs in the lungs are damaged, usually as a result of long-term smoking. It causes difficulty breathing and shortness of breath that gets worse over time.
Emphysema is a form of chronic obstructive pulmonary disease (COPD).
A rare type of emphysema is caused by the lack of a substance in the lungs called alpha1-antitrypsin. This type of emphysema is usually inherited.
