Chronic bronchitis is a long-term disease of the lungs. It is a problem with the airways of the lungs. Injury or irritation causes these airways to swell and develop extra mucus. This makes it difficult to move air in and out of the lungs. It will make breathing difficult.
Cigarette smoking is the greatest risk factor for developing chronic bronchitis. The more you smoke and the longer you smoke, the greater your chance of developing chronic bronchitis. Frequent and long-term smoking also increases the chance of severe chronic bronchitis.
Chronic bronchitis is more common in people over 40 years old. Other factors that may increase your risk of chronic bronchitis include:
Long-term exposure to chemicals, dust, and other substances that have been inhaled
