What exactly is gerd?

(GERD) Gastroesophageal Reflux Disease, aka Reflux, is a very common disease of the digestive system. GERD is the result of a weak LES (lower esophageal sphincter).

The LES is a ring of muscle that connects the esophagus to the stomach. The LES acts as a gatekeeper, it opens when you swallow allowing food to pass into your stomach and then in an ideal world closing to prevent the contents of your stomach from coming back up (Refluxing).

When this happens people with GERD may experience a burning sensation from mild soreness to extreme burning. The lining of the esophagus is very sensitive and can easily be irritated by anything that might have been in your stomach.
