Barrett's esophagus is a serious complication of GERD, which stands for gastroesophageal reflux disease. In Barrett's esophagus, normal tissue lining the esophagus -- the tube that carries food from the mouth to the stomach -- changes to tissue that resembles the lining of the intestine. About 10%-15% of people with chronic symptoms of GERD develop Barrett's esophagus.
Barrett's esophagus does not have any specific symptoms. Patients with Barrett's esophagus may have symptoms related to GERD. It does, though, increase the risk of developing esophageal adenocarcinoma, which is a serious, potentially fatal cancer of the esophagus.
Although the risk of this cancer is higher in people with Barrett's esophagus, the disease is still rare. Less than 1% of the people with Barrett's esophagus develop this particular cancer. Nevertheless, if you've been diagnosed with Barrett's esophagus, it's important to have routine examinations of your esophagus. With routine examination, your doctor can discover precancerous and cancer cells early, before they spread and when the disease is easier to treat.
