According to the American Lung Association, about 11.1 million U.S. adults live with chronic obstructive pulmonary disease (COPD), though many more may be undiagnosed. COPD, which includes emphysema and chronic bronchitis, is most often caused by long-term exposure to smoke, fumes, dust, or chemicals—most commonly from cigarette smoke.
Chronic bronchitis causes airway inflammation and mucus buildup. Emphysema damages air sacs in the lungs, reducing oxygen flow. Symptoms include shortness of breath, wheezing, chest tightness, fatigue, coughing with mucus, and frequent lung infections. While COPD is progressive, it is treatable with early care.
If you experience any symptoms, let your healthcare provider know.
