Commonly known as GERD, gastroesophageal reflux disease is a chronic disease that occurs as a result of persistent acid reflux, which, in turn, occurs when stomach acid flows back up from the stomach into the esophagus. In some cases, bile may flow into the esophagus as well. Most often, many of the uncomfortable and painful signs and symptoms of GERD are caused by the backwash of acid irritating the lining of the esophagus.
