Barrett’s esophagus is a condition in which the flat pink lining of the swallowing tube that connects the mouth to the stomach (esophagus) becomes damaged by acid reflux, which causes the lining to thicken and become red.

Between the esophagus and the stomach is a critically important valve, the lower esophageal sphincter (LES). Over time, the LES may begin to fail, leading to acid and chemical damage of the esophagus, a condition called gastroesophageal reflux disease (GERD). GERD is often accompanied by symptoms such as heartburn or regurgitation. In some people, this GERD may trigger a change in the cells lining the lower esophagus, causing Barrett’s esophagus.

Barrett’s esophagus is associated with an increased risk of developing esophageal cancer. Although the risk of developing esophageal cancer is small, it’s important to have regular checkups with careful imaging and extensive biopsies of the esophagus to check for precancerous cells (dysplasia). If precancerous cells are discovered, they can be treated to prevent esophageal cancer.

When to see a Doctor

If you’ve had trouble with heartburn, regurgitation and acid reflux for more than five years, then you should ask your doctor about your risk of Barrett’s esophagus.

Seek immediate help if you:

  • Have chest pain, which may be a symptom of a heart attack
  • Have difficulty swallowing
  • Are vomiting red blood or blood that looks like coffee grounds
  • Are passing black, tarry or bloody stools
  • Are unintentionally losing weight
