Acid Reflux (Sometimes called Gastroesophageal Reflux Disease [or GERD]) is a medical condition that is created when your esophagus becomes inflamed or irritated because of acid infiltrating it from the stomach.  The lower esophageal sphincter is supposed to prevent food and acid from escaping the stomach back into the esophagus, but if you suffer from Acid Reflux, the sphincter relaxes between swallowing, and allows the acid to move up into your esophagus and sometimes further.

According to studies, nearly one-third of adults in the United States suffer from Acid Reflux on a regular basis.  According to the same studies, approximately 10% of the adults in the United States exhibit symptoms of Acid Reflux on a weekly (or sometimes more frequently) basis.
