Bronchitis
The Basics
Bronchitis is a condition in which the bronchial tubes, the tubes that carry air to your lungs, become inflamed. People who have bronchitis often have a cough that brings up mucus. Mucus is a slimy substance made by the lining of the bronchial tubes. Bronchitis also may cause wheezing (a whistling or squeaky sound when you breathe), chest pain or discomfort, a low fever, and shortness of breath.
There are two main types of bronchitis: acute (short term) and chronic (ongoing). For either acute bronchitis or chronic bronchitis, signs and symptoms may include:
- Cough
- Production of mucus (sputum), either clear or white or yellowish-gray or green in color
- Shortness of breath, made worse by mild exertion
- Wheezing
- Fatigue
- Slight fever and chills
- Chest discomfort
