Barrett's Oesophagus: Complete Guide

Barrett's oesophagus is a change in the oesophageal lining caused by chronic acid reflux, and carries a small but important risk of progressing to oesophageal cancer.

Cause
Chronic GERD (acid reflux)
Cancer risk
~0.5% per year (low but important)
Diagnosis
Endoscopy with biopsy
Surveillance
Regular endoscopy if diagnosed

How It Develops

Chronic exposure to stomach acid causes the normal squamous lining of the lower oesophagus to be replaced by a different, more acid-resistant cell type (intestinal metaplasia) — this change is called Barrett's oesophagus.

Risk Factors

Surveillance and Dysplasia Grading

FindingSurveillance Interval
No dysplasiaEvery 3-5 years
Low-grade dysplasiaEvery 6-12 months, or treatment
High-grade dysplasiaTreatment recommended — endoscopic ablation or resection
PPI Treatment Is EssentialLong-term proton pump inhibitor (PPI) therapy is standard for Barrett's oesophagus to control acid exposure, alongside regular endoscopic surveillance to detect any progression toward cancer early.
Does having Barrett's mean I'll get cancer?
No — the annual risk of progression to oesophageal cancer is low (around 0.5% per year for non-dysplastic Barrett's), but regular surveillance is important to catch any early changes.
Can Barrett's oesophagus be reversed?
Endoscopic treatments (radiofrequency ablation) can remove Barrett's tissue in cases with dysplasia, but simple lifestyle and medication changes don't typically reverse established Barrett's, though they control symptoms and reduce further risk.
