Chronic obstructive pulmonary disease (COPD) is a term that is used for progressive lung diseases. Chronic bronchitis and emphysema are common types of COPD. These diseases make it hard for you to breathe, and coughing up mucus is often one of the first signs of COPD.
Your airways branch out inside your lungs like an upside-down tree. At the end of each branch are small, balloon-like air sacs. In healthy people, both the airways and air sacs are springy and elastic. When you breathe in, each air sac fills with air like a small balloon. The balloon deflates when you exhale. In COPD, your airways and air sacs lose their shape and become floppy, like a stretched-out rubber band.
Cigarette smoking is the most common cause of COPD, so quitting smoking is the best way to avoid developing COPD. Breathing in other kinds of lung irritants — like pollution, dust, or chemicals — over a long period of time may also cause or contribute to COPD.
Treatment can make you more comfortable, but there is no cure.
