Causes



Smoking tobacco causes 80% to 90% of COPD cases. An agent in tobacco smoke stimulates inflammation in the lungs, leading to destruction of the alveoli and narrowing of the airways.

According to the World Health Organization (WHO):

"The most important risk factors for COPD are tobacco smoking, indoor air pollution (such as biomass fuel used for cooking and heating), outdoor air pollution, and occupational dusts and chemicals (vapors, irritants, and fumes)."

According to the National Heart, Lung, and Blood Institute of the NIH:

"Cigarette smoking is the most common cause of COPD. Most people with COPD are smokers or former smokers. Breathing in other kinds of lung irritants, like pollution, dust, or chemicals, over a long period of time may also cause or contribute to COPD."

According to the American Lung Association:

"Smoking is the primary risk factor for COPD. Other risk factors of COPD include air pollution, second-hand smoke, history of childhood respiratory infections and heredity. Occupational exposure to certain industrial pollutants also increases the odds for COPD."
