(Condition shown: Emphysema)
If you have emphysema, the muscles that help you breathe have to work harder. They also tire out sooner. The result?
You feel short of breath after the slightest activity. As the disease gets worse, you may feel breathless even when you’re sitting still.
This happens as a result of changes in the lungs that occur over a period of years due to lung damage. Most often it’s caused by smoking.
