Digestive SystemAcid Reflux Disease GERD (Gastro Esophageal Reflux Disease) is a disease that happens when acid and other materials in the stomach back flow or reflux into the esophagus. In most cases, the reflux of the materials in the stomach stay in the lower part of the esphagus but in some cases the reflux of the materials in the stomach will back up all the way into your mouth.
The most common acid reflux cause is an esphageal sphincter that is weak and does not work properly. An esphageal sphincter is a tough layer of muscle that surrounds the lower end of the esphagus. Every time you eat food, the sphincter contracts strongly to push the food into your stomach in order to prevent it from backing up into your throat or mouth.
