WHAT IS GASTROESOPHAGEAL REFLUX DISEASE (GERD)?

The term gastroesophageal reflux describes the movement (or reflux) of stomach contents back up into the esophagus, the muscular tube that extends from the neck to the abdomen and connects the back of the throat to the stomach. Because the stomach manufactures acid as an aid to digestion, this phenomenon is often referred to as acid reflux. Most people experience acid reflux from time to time as heartburn, a burning sensation below the breast bone that occurs after eating or at night. When the frequency of acid reflux is much greater than normal, or complications develop as a result of acid reflux, the condition is known as gastroesophageal reflux disease, or GERD.
