Chronic Cough

A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children. A chronic cough is more than just annoying. It can interrupt your sleep and leave you feeling very tired. Severe cases of chronic cough can cause vomiting and lightheadedness, and even break a rib.

The most common causes are tobacco use and asthma. Other common causes include fluid that drips from the nose down the back of the throat, called postnasal drip, and the backward flow of stomach acid into the tube that connects the throat to the stomach, called acid reflux. Fortunately, chronic cough usually goes away once the underlying issue is treated.
