Barrett's esophagus is a condition in which the lining of the esophagus, the tube that carries food from the mouth to the stomach, is replaced by tissue that is similar to the lining of the intestine. This condition is caused by long-term exposure to stomach acid due to gastroesophageal reflux disease (GERD). The presence of Barrett's esophagus increases the risk of developing esophageal cancer. Symptoms of Barrett's esophagus include heartburn, chest pain, difficulty swallowing, and regurgitation. Treatment for Barrett's esophagus may include medications to reduce stomach acid, lifestyle changes, and in some cases, surgery.
