What is gastroesophageal reflux disease (GERD)?
Reflux means that stomach acid and juices flow from the stomach back up into the tube that leads from the throat to the stomach (esophagus). This causes heartburn. When you have heartburn at least 2 times a week, it is called gastroesophageal reflux disease, or 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.
