a progressive lung disease, caused by damage to the small air sacs (alveoli) and airways in your lungs. This damage reduces and obstructs your airflow during exhalation.
This damage is progressive and irreversible, and may take years or even decades manifest. In its advanced stages, the simple act of breathing can take almost all the energy a person has, thus limiting or preventing further physical activity.
Emphysema is the fourth largest cause of death in the United States, killing approximately 100,000 sufferers per year.
