emphysema 1


Emphysema is a form of chronic (long-term) lung disease. People with emphysema have difficulty breathing from a limitation in blowing air out. There are multiple causes of emphysema, but smoking is by far the most common.


Emphysema is one of the main types of chronic obstructive pulmonary disease (COPD). It’s called “obstructive” because people with emphysema exhale as if something were obstructing the flow of air. The other form of COPD is chronic bronchitis, which can also be caused by smoking.


Although emphysema has no cure, quitting smoking reduces the speed at which the disease gets worse.
