Gastroesophageal reflux (GER) is the back up of acid or food from the stomach to the esophagus. The esophagus is the tube that connects your mouth and stomach. GER is common in infants. It may cause them to spit up. Most infants outgrow GER within 12 months.

GER that progresses to esophageal injury and other symptoms is called gastroesophageal reflux disease (GERD). The backed-up acid irritates the lining of the esophagus. It causes heartburn, a pain in the stomach and chest.

GERD can occur at any age.
