What causes chronic obstructive pulmonary disease (COPD)?

ANSWER

Cigarette smoking is the biggest cause. If you're around other smokers a lot, that can play a role, too. You might also get this condition if you’ve been exposed to things like dust, air pollution, or certain chemicals for long periods of time.

In rare cases, your genes may put you at risk for COPD.
