Gastroesophageal reflux disease (GERD) can occur in children when there is an abundance or buildup of acid in the stomach that begins to affect the esophagus. The most common symptom is burning in the chest that usually occurs after eating and intensifies when lying down. Complications from GERD can occur in children and young adults if chronic inflammation persists in the esophagus. These complications may include narrowing of the esophagus, an open sore in the esophagus, or precancerous changes to the esophagus. Initially, complications of GERD may be controlled by over-the-counter treatments to lessen heartburn and acid reflux. If the condition is more severe, then surgery may be required in order to reinforce the lower esophageal sphincter and/or to create a barrier to prevent the backup of stomach acid.
