A Brief Overview of GERD
A chronic digestive disorder, GERD or gastroesophageal reflux disease affects the lower esophageal sphincter (LES), which is located between the esophagus and the stomach. It occurs when bile or stomach acid flows into the esophagus and irritates the esophageal lining. People with GERD often experience heartburn or acid reflux. This condition is quite common, but it can be a cause for concern if a person suffers from acid reflux frequently.
