Overview
GERD occurs when stomach acid refluxes into the esophagus, past the Lower Esophageal Sphincter (LES) and irritates the mucous membrane and inner lining. If you suffer from GERD, you might experience it as heartburn or acid indigestion. Acid reflux is common, but when it turns chronic (at least twice a week, of moderate-intensity), it could be GERD and the patient must seek help.
