COPD is a lung disease that makes it hard to breathe. COPD stands for chronic obstructive pulmonary disease. It is caused by damage to the lungs over many years, usually from smoking.

Other things that may put you at risk for COPD include breathing chemical fumes, dust, or air pollution over a long period of time. Secondhand smoke is also bad.


COPD is almost always caused by smoking. In some cases, COPD may be caused by a rare gene change that affects the body’s ability to protect the lungs from damage.
