What causes COPD?
While there are many causes of COPD, smoking is the most common. Certain environmental factors and genetic conditions can also cause the disease. Those assigned female at birth or over age 65 may be at higher risk.
Smoking is the main cause of chronic obstructive pulmonary disease. While some people smoke for years and never get COPD, the more you smoke, the more likely you will develop the disease.
Some forms of COPD can be traced to environmental risk factors, including:
- Exposure to certain gases or fumes in the workplace
- Exposure to heavy amounts of secondhand smoke and pollution
- Frequent use of a cooking fire without proper ventilation
Some people have a rare condition in which they lack a protein called alpha-1 antitrypsin. They can develop emphysema even without smoking.
