Barrett's Esophagus: Who Should Be Checked and How It's Treated

Ken D. Nguyen, MD · Oct 23, 2026 · 1 min read

Barrett's esophagus is a condition in which the normal lining of the lower esophagus is replaced by tissue that looks more like the lining of the intestine. It develops in some people with long-term acid reflux (GERD). Barrett's itself causes no symptoms, but it slightly increases the risk of esophageal cancer.

Who should be checked?

Screening is usually recommended for people with chronic reflux symptoms plus several of these risk factors:

  • Male sex
  • Age over 50
  • White race
  • Excess weight around the waist
  • Current or past smoking
  • A close relative with Barrett's esophagus or esophageal cancer

Diagnosis

Barrett's is found during an upper endoscopy (EGD). We take small biopsies to confirm it and check for dysplasia, which means pre-cancerous changes in the cells.

Treatment and follow-up

  • No dysplasia: acid-reducing medicine and repeat endoscopy every few years
  • Low-grade dysplasia: closer surveillance or endoscopic treatment
  • High-grade dysplasia or very early cancer: endoscopic removal of the abnormal tissue and ablation, such as radiofrequency ablation, which usually avoids surgery

Lowering your risk

  • Control reflux with lifestyle changes and medicine
  • Stop smoking
  • Reach a healthy weight

Quick Answers

Does Barrett's esophagus turn into cancer?

Rarely. Most people with Barrett's never develop cancer, but the risk is higher than average, so regular check-ups with endoscopy are recommended.

Who should be screened for Barrett's esophagus?

People with long-standing reflux who also have other risk factors, such as being male, over 50, white, overweight around the waist, a smoker, or having a family history of Barrett's or esophageal cancer.

How is Barrett's esophagus treated?

Acid-reducing medicine and regular endoscopy for most people. If pre-cancerous changes (dysplasia) are found, the abnormal lining can be removed or destroyed during endoscopy.
