Chronic bronchitis is the more serious bronchitis than acute bronchitis, the other type of bronchitis. Once you get it, it keeps coming back or doesn't go away at all.
It's one of the conditions that makes up what's called chronic obstructive pulmonary disease (COPD), a lung disease that makes it hard to breathe. People who smoke are more likely to get it. It makes your lungs a breeding ground for bacterial infections and may require ongoing medical treatment.
