This is a disease that affects your mucus and sweat glands. It causes the mucus your body produces to be thick and sticky. In your lungs, sticky mucus can clog your airways. This makes it hard for you to breathe. It also provides a place for bacteria to grow. That can lead to frequent lung infections.
This is a chronic and progressive disease of your lungs. It involves the tiny air sacs, called "alveoli", at the ends of the air passages in your lungs. In healthy lungs, these sacs inflate and deflate as you breathe. But with emphysema, the walls of these sacs break down. The sacs begin to rupture. This interferes with your lungs' ability to cycle air properly.
