Chronic bronchitis is an inflammation or irritation of the airways in the lungs. Bronchitis generally causes a cough that produces mucus, which often leads to shortness of breath, wheezing, and chest tightness. Acute bronchitis is generally caused by a viral or bacterial infection and usually resolves itself fairly quickly. Cigarette smoking is the most common cause of chronic bronchitis. A clinical diagnosis of chronic bronchitis requires the presence of a productive cough (i.e. mucus producing) occurring most days of the month for at least three months of the year for two consecutive years. In chronic bronchitis, persistent inflammation can eventually cause scarring and thickening of the body’s airways, exacerbating the problem.
Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is a chronic lung disease that makes it hard to breathe. The disease is increasingly common, affecting millions of Americans, and is the third leading cause of death in the U.S. More than 11 million people in the U.S. suffer from COPD. It causes serious long-term disability and early death. There's no cure, but COPD can be prevented and treated.Click here to download Breathe Easy Arizona’s COPD Awareness poster
