Barrett’s esophagus
Definition
Barrett's esophagus is a disorder in which the lining of the esophagus (the tube that carries food from the throat to the stomach) is damaged. The damage is caused by stomach acid that leaks back into the esophagus. This leakage of acid is commonly known as "heartburn" (gastroesophageal reflux).
Causes
Irritation of the lining of the esophagus by stomach acid causes Barrett's esophagus. It happens more frequently in men than women. Risk factors are frequent and long-standing gastroesophageal reflux. The condition carries an increased risk of cancer of the esophagus.
