Bronchitis

Q:  You've commented on several seasonal hazards but have not mentioned bronchitis. Just what is it and what should you do if you have it?

A:  Bronchitis is an inflammation of the small airways in the lungs. Usually this is associated with a moist cough that is mucus producing.

In the vast majority of people with this condition, the cause can be traced to a cold virus. As long as there is no fever or unusual shortness of breath, the treatment of choice is clear liquids and over-the-counter cough suppressants. Historically we physicians have probably over-prescribed antibiotics for this condition and may have unintentionally contributed to the appearance of some bacterial resistance.

The presence of a fever, the existence of a chronic disease such as asthma or emphysema, severe shortness of breath, or a weak immune system may warrant further investigation. A chest x-ray may be helpful and the prescription of antibiotics may be necessary.
