Emphysema damages the tiny air sacs in the lungs, which inflate when we take in a breath and move oxygen into the blood. They also push out carbon dioxide, a waste gas, when we breathe out. When you have emphysema, these delicate air sacs can't expand and contract properly.
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).ost commonly, the toxins in cigarette smoke create the damage. The lung changes of emphysema evolve slowly over years: 1  As the fragile tissues between air sacs are destroyed, air pockets in the lungs develop. 2  Air becomes trapped in these spaces of damaged lung tissue.
