Bronchitis
Bronchitis is an inflammation of the lining in the bronchial
tubes, which is the airway that connects the windpipe to the lungs. When
bronchitis is contracted, it is often painful and difficult for air to pass
through in and out of the lungs when breathing.
The main sign of bronchitis is a cough, which brings up
mucus that can be caused either by a virus, or by exposure to irritants such as
dust and fumes, or cigarette smoke.
The majority of cases of bronchitis stem from viral
infections, and require nothing more than treatment of the symptoms to relieve
discomfort.
