COPD stands for "chronic obstructive pulmonary disease." COPD is a lung disease. People with COPD have a hard time getting air in and out of their lungs.
COPD is sometimes called chronic bronchitis (bron-ki'-tis) or emphysema (em-fih-see'-muh). People can get COPD from smoking. However, some people get it from being around other people who smoke or from breathing dirty air. COPD can make people:
- Feel like they can't catch their breath.
- Cough a lot.
- Cough up more mucus or phlegm.
- Feel like their chest is tight.
