Barrett's oesophagus: what patients in the UK should know

It is not the same as oesophageal cancer. A specialist uses the endoscopy appearance and biopsy findings to confirm the diagnosis, check for dysplasia and decide whether surveillance or treatment is appropriate.

The oesophagus is the tube carrying food to the stomach. With Barrett's oesophagus, cells in part of its lining have changed, often after long-standing acid reflux. The change itself may cause no symptoms; heartburn and regurgitation usually come from the underlying reflux.

A biopsy report may say there is no dysplasia or may describe dysplasia, meaning abnormal precancerous cell changes. Dysplasia is not a cancer diagnosis, but it can change the recommended follow-up. Your plan also depends on the length of affected lining, your general health and whether a procedure would benefit you.

Take acid-suppressing medicine exactly as prescribed, even when reflux feels controlled, and check before stopping it. Keep your endoscopy or other surveillance appointments because tissue samples can detect cell changes that symptoms cannot reveal. Ask when the biopsy result will arrive and who will explain it.

Notice which meals or drinks worsen your reflux. Smaller meals, avoiding food close to bedtime, stopping smoking and working toward a comfortable weight may reduce reflux for some people. These measures support symptom control but do not replace prescribed medicine or surveillance.

Contact your GP promptly for new or worsening difficulty swallowing, pain when swallowing, food sticking, repeated vomiting, unexplained weight loss or reflux that has clearly changed. These symptoms need assessment regardless of when your next surveillance appointment is due.

Seek urgent medical help for vomiting blood, black tar-like stools, severe chest or upper abdominal pain, fainting, or breathing difficulty. After an endoscopy, follow the unit's discharge instructions and get urgent advice for severe pain, fever, breathlessness or significant bleeding.

Ask whether biopsies confirmed Barrett's oesophagus, whether dysplasia was found, and how the result affects your personal follow-up plan. You can also ask what your medicine is intended to do, which symptoms should trigger an earlier review, and whether endoscopic treatment is relevant to your findings.
