Emphysema is a long-term disease of the lungs. It is a problem with the tiny air sacs that make up the lungs. These tiny elastic sacs should stretch to fill with air and then get smaller as air moves out of the lungs. Emphysema is caused by the destruction of these air sacs. This makes it difficult to move air in and out of the lungs.
Emphysema is a type of chronic obstructive pulmonary disease (COPD).
