Emphysema is a form of chronic (long-term) lung disease, usually caused by smoking. Because of lung damage, people with emphysema have difficulty blowing air out.
The major symptom of emphysema is shortness of breath. In most people, symptoms of emphysema are slowly progressive. Emphysema symptoms also include cough and wheezing.
Emphysema Symptoms: Breathlessness Most Common
Shortness of breath is by far the most common of emphysema symptoms. Most people with emphysema first notice something's wrong when they become winded during a previously routine activity. This might be climbing stairs or mowing the lawn.
The shortness of breath in emphysema results from structural changes in the lungs. These occur over years in response to lung damage, usually from smoking:
The linings between air sacs are destroyed, creating air pockets in the lungs.
Air is trapped in these air pockets and is difficult to breathe out.
