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.
Long-term exposure to stomach acid is the single biggest driver of Barrett's oesophagus.
Excess abdominal weight increases stomach pressure, worsening reflux and raising risk.
Weakens the lower oesophageal sphincter and speeds up acid-related tissue damage.
Men aged 50 and over are significantly more likely to develop the condition.
A close relative with Barrett's oesophagus or oesophageal cancer raises your risk.
Regular alcohol intake irritates the oesophageal lining and aggravates reflux.
Barrett's oesophagus is often asymptomatic. When symptoms occur, they are usually linked to underlying GORD.
A burning sensation in the chest or throat, often worse after meals or when lying flat.
The feeling that food is sticking or moving slowly through the gullet.
Always worth investigating promptly.
A sour or bitter taste as stomach contents flow back into the mouth after eating.
Persistent nausea, particularly after meals or on waking in the morning.
Excessive belching, often accompanied by bloating or upper abdominal discomfort.

Treatment aims to manage symptoms, prevent progression, and reduce cancer risk. Dr Rajendran tailors every plan to the individual.
PPIs, antacids, and H2 blockers reduce stomach acid, relieve symptoms, and slow oesophageal damage.
A targeted endoscopic procedure that destroys abnormal Barrett's cells using controlled heat energy.
