Bronchitis is an inflammation of the lining of your bronchial tubes. These tubes carry air to and from your lungs. Bronchitis may start suddenly and be short term (acute) or start gradually and become long term (chronic).

Acute bronchitis, which often develops from a cold or other respiratory infection, is very common. Also called a chest cold, acute bronchitis usually improves within a week to 10 days without lasting effects, although the cough may linger for weeks.

Chronic bronchitis, a more serious condition, is a constant irritation or inflammation of the lining of the bronchial tubes, often due to smoking.
