The main risk factor for COPD is smoking. Most people who have COPD smoke or used to smoke. People who have a family history of COPD are more likely to develop the disease if they smoke.
Long-term exposure to other lung irritants also is a risk factor for COPD. Examples of other lung irritants include secondhand smoke, air pollution, and chemical fumes and dust from the environment or workplace. (Secondhand smoke is smoke in the air from other people smoking.)
Most people who have COPD are at least 40 years old when symptoms begin. Although uncommon, people younger than 40 can have COPD. For example, this may happen if a person has alpha-1 antitrypsin deficiency, a genetic condition.

NIH survey identifies barriers to effective patient-provider dialogue about COPD
Lack of communication between patients and health care providers about chronic obstructive pulmonary disease (COPD) remains a major barrier to diagnosis of this disease, according to the results of a Web-based survey released today by the National Heart Lung, and Blood Institute (NHLBI) of the National Institutes of Health.
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
