Digestive condition in which stomach acid or bile irritates the lining of the food pipe, called the esophagus.

Gastroesophageal reflux disease (GERD) is an ongoing condition that happens when stomach acid or bile flows into the food pipe and irritates its lining. Having acid reflux and heartburn more than twice a week may indicate GERD.

Symptoms include a burning or painful sensation in the chest that often happens after eating, backwash of food or sour liquid in the throat, and trouble swallowing.

Relief that results from lifestyle changes and nonprescription medicines is usually temporary. Stronger medicine may be needed.
