DefinitionBy Mayo Clinic Staff
In Barrett's esophagus, tissue in the tube connecting your mouth and stomach (esophagus) is replaced by tissue similar to the intestinal lining.
Barrett's esophagus is most often diagnosed in people who have long-term gastroesophageal reflux disease (GERD) — a chronic regurgitation of acid from the stomach into the lower esophagus. Only a small percentage of people with GERD will develop Barrett's esophagus.
Barrett's esophagus is associated with an increased risk of developing esophageal cancer. Although the risk is small, it's important to have regular checkups for precancerous cells. If precancerous cells are discovered, they can be treated to prevent esophageal cancer.
