What causes Barrett’s esophagus?

Multiple factors contribute to Barrett’s esophagus. It’s more common in people with GERD. This chronic (ongoing) condition occurs when stomach contents flow backward into the esophagus. Experts believe the acidic liquid irritates the lining of the esophagus, leading to changes in the tissue. But you can also have Barrett’s esophagus without having GERD.
