BARRETT'S DISEASE
Barrett's esophagus is a disorder in which the lining of the esophagus (the tube that carries food 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). 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.
Barrett's esophagus itself does not cause symptoms. The acid reflux that causes Barrett's esophagus results in symptoms of heartburn. Rarely, Barrett's esophagus can progress to cancer of the esophagus, the symptoms of which may be difficulty swallowing or weight loss.
Looking at the esophagus with an endoscope and obtaining a sample of esophagus tissue for examination (esophagoscopy with biopsy) may reveal Barrett's esophagus. A barium x-ray of the Esophagus will not show the flat changes of Barrett's esophagus. (Sources: National Library of Medicine, Medical Encyclopedia 2007. American College of Gastroenterology 2007)
