In a normal digestive system

* The muscles that line your digestive system push food along in one direction.
* Special muscles called "sphincters" serve as valves that squeeze shut between one section of your digestive system and the next. Ordinarily, they allow food to pass only in one direction.
* Acid in the stomach helps digest food. The stomach lining resists the damaging effects of this acid.

When GERD strikes

* The sphincter between the stomach and the esophagus becomes loose or relaxes at the wrong time, allowing stomach acid to flow into the esophagus (acid reflux).
* Repeated acid reflux causes erosions or sores in the lining of the esophagus ("erosive esophagitis"), leading to pain or discomfort.
* GERD symptoms can be worse at night.
