Symptoms, causes, and treatments for
Bronchitis, sometimes called a chest cold, is an infection of the lungs and bronchial tubes. Usually, bronchitis appears after you've had a cold or flu illness for an extended period. If those underlying illnesses aren't adequately treated, they can creep into your chest and create a more severe infection.
Symptoms common to bronchitis include:
Acute bronchitis is a short-lived viral infection of your lungs, and it usually progresses from a previous cold or flu. Acute bronchitis may last up to three weeks, and your coughs will produce a lot of mucus. That's a good thing: doctors call that a productive cough, and it's better to get the excess mucus out.
Chronic bronchitis is a repeated bronchial infection generally caused by smoking or inhaling harsh or dangerous chemicals and particulates. Chronic infections are resistant to treatment.
