What is Barrett's esophagus?

Barrett’s esophagus is a change in the tissue lining your esophagus, the tube in your throat that carries food to your stomach. For reasons no one understands completely, cells in the esophageal lining sometimes become more like intestinal cells.

Researchers suspect that having acid reflux or gastroesophageal reflux disease (GERD) is related to Barrett’s esophagus. Barrett’s esophagus raises the risk of developing a rare esophageal cancer.
