What is Barrett's esophagus?
Barrett's esophagus is a condition in which the lower portion of the esophagus changes, due to the chronic effects of stomach acid splashing back into the esophagus. The esophagus is the muscular tube that carries food and saliva from the mouth to the stomach.

What are the symptoms of Barrett's esophagus?
Common symptoms of Barrett's esophagus include recurrent heartburn. Barrett's may cause no symptoms at all, but a small number (less than 1%) of people with Barrett's can develop esophageal cancer.

How does the doctor treat Barrett's esophagus?
Treatment for Barrett's esophagus involves controlling acid reflux. Measures include weight reduction, exercise, stopping smoking, and avoiding foods that trigger heartburn. Medications may include antacids and other drugs that decrease acid in the stomach, such as H2 antagonists, and proton pump inhibitors. Surgery may be an option for those who fail to control symptoms with medications.
