Barrett's oesophagus occurs when cells lining the oesophagus change abnormally, most often due to long-term acid reflux (gastroesophageal reflux disease — GORD).
It is a known risk factor for oesophageal cancer, though the risk remains low for most people.
Early diagnosis and treatment can effectively manage the condition.
Caused by prolonged acid damage to the oesophagus lining.
Strongly linked to GORD, obesity, smoking, and lifestyle factors.
Diagnosed through endoscopy and biopsy.
Regular surveillance is essential once diagnosed.
The primary cause is chronic acid reflux (GORD). Several additional factors can raise the risk.
Persistent stomach acid exposure is the most common cause of abnormal cellular changes.
Excess abdominal weight increases pressure on the stomach, worsening reflux symptoms.
Smoking, being male and over 50, a family history of Barrett's, and excessive alcohol all raise risk.
Barrett's oesophagus is often asymptomatic. When symptoms occur, they are usually linked to underlying GORD.
Burning in the chest or throat, especially after eating or lying down.
Food or liquid feeling as though it sticks in the chest or throat.
A burning or dull ache behind the breastbone, sometimes mistaken for cardiac issues.
A sour or bitter taste from stomach acid rising back into the throat.
Important Note: Many people with Barrett’s oesophagus have no symptoms at all. If you have persistent reflux or are at risk, a specialist assessment is strongly advised.
Expert care for Barrett's oesophagus is available in London. Book your consultation with Dr. Arun Rajendran today.
The most effective way to diagnose Barrett's oesophagus is through endoscopy — a camera examination of the oesophagus. A biopsy may also be taken to check for precancerous cell changes.

Tissue samples checked for dysplasia (precancerous changes) if needed.

PPIs, antacids, and H2 blockers reduce stomach acid, relieve symptoms, and slow oesophageal damage.

EMR removes abnormal tissue; regular surveillance endoscopies monitor for any progression over time.

Targeted lifestyle changes can reduce risk and help manage Barrett's oesophagus symptoms day to day.
