What is Emphysema?
Emphysema is a serious disease that affects the lungs. While symptoms may appear rapidly and quickly become severe, the disease itself develops over a long period of time.
When a person is suffering from emphysema, the tiny air sacs (called alveoli) in the lungs are damaged and lose their ability to stretch. This allows air to become trapped in the lungs, making it difficult to exchange with new air. This makes it hard to breathe and can lead to a host of lung problems as well as death.
