Health Topics: Digestive Health: Heartburn & GERD

Eating too much or bending forward after eating sometimes causes heartburn and a sour taste in the mouth. But having heartburn from time to time doesn't mean you have GERD. With GERD, the reflux—and heartburn—last longer and come more often. If this happens to you, it is important to treat it, because GERD can cause ulcers and damage to the esophagus.
