Risk Factors

The number one risk factor for developing COPD is smoking. People who smoke or used to smoke are at a much greater risk for COPD than those who have never smoked.

Exposure to other lung irritants can also increase your risk for developing COPD. Some of those lung irritants are:

  • Secondhand smoke
  • Air pollution
  • Chemical fumes
  • Dust from the environment or workplace

Rarely, development of COPD is related to a genetic condition called alpha-1 antitrypsin deficiency. People with this condition have a low level of alpha-1 antritypsin (AAT), which is a protein made in the liver. Low levels of AAT make people more susceptible to smoke exposure and other lung irritants. COPD can worsen rapidly in people who smoke and have AAT deficiency.
