Breathe Easier: 10 Amazing Activities Proven to Improve COPD Symptoms

8. Causes

Tobacco smoke is the leading cause of COPD in developed countries. In developing countries, exposure to fumes from burning fuel for cooking or heat from poorly ventilated homes commonly cause COPD. Approximately twenty to thirty percent of chronic smokers may develop COPD. Even if a smoker is not diagnosed with COPD, they may eventually develop reduced lung function. Other smokers will develop less commonly known lung conditions or may be misdiagnosed. Genetics can also play a role in COPD even if a person has never been exposed to fumes or smoke.
