Medicines for Barrett's oesophagus
A change in the cells lining the lower gullet (oesophagus) caused by long-term acid reflux — usually it causes no symptoms of its own beyond the reflux, but because it slightly raises the long-term risk of oesophageal cancer it is monitored with periodic endoscopy, while acid is controlled with a PPI.

Quick answer
What is Barrett's oesophagus?
Barrett's oesophagus is a change in the cells that line the lower part of the gullet (oesophagus), the tube that carries food from the mouth to the stomach. It develops as a response to long-term acid reflux — when stomach acid repeatedly comes back up into the gullet (gastro-oesophageal reflux disease, or GORD) — and the lining gradually changes to a type more like that of the intestine.
- How it is treated: Management of Barrett's oesophagus has two main strands: controlling the acid reflux that underlies it, and keeping a careful eye on the lining over time so that any worrying changes are caught early.
- Self-care: Measures that reduce acid reflux can help with symptoms and form part of looking after the gullet: reaching and keeping a healthy weight, eating smaller meals, avoiding eating late at night and lying down soon after eating, raising the head of the bed, cutting down on triggers such as alcohol, caffeine, fatty or spicy foods, and stopping smoking.
- When to seek help: If you have known Barrett's oesophagus, keep to the surveillance endoscopy appointments your specialist arranges, as these are how any early changes in the lining are picked up over time.
What it is
Barrett's oesophagus is a change in the cells that line the lower part of the gullet (oesophagus), the tube that carries food from the mouth to the stomach. It develops as a response to long-term acid reflux — when stomach acid repeatedly comes back up into the gullet (gastro-oesophageal reflux disease, or GORD) — and the lining gradually changes to a type more like that of the intestine. In itself, Barrett's oesophagus usually causes no symptoms beyond those of the reflux that led to it, such as heartburn or an acid taste, and many people would not know they had it without an endoscopy (a test in which a thin flexible camera is passed down to look at the gullet). The reason it matters is that, over many years, the changed lining carries a slightly increased risk of developing into oesophageal cancer. It is important to keep this in proportion: the great majority of people with Barrett's oesophagus never go on to develop cancer. But because the risk is raised compared with normal lining, it is taken seriously, monitored over time, and acid reflux is controlled to ease symptoms and as part of overall management.
How it is treated
Management of Barrett's oesophagus has two main strands: controlling the acid reflux that underlies it, and keeping a careful eye on the lining over time so that any worrying changes are caught early. Acid is controlled with a proton pump inhibitor (a PPI), a medicine that strongly reduces acid production; this eases reflux symptoms and is used as part of managing the condition. Alongside this, the lining is monitored with periodic endoscopy — known as surveillance — in which a camera examines the gullet and small samples (biopsies) may be taken to check the cells, at intervals decided by a specialist based on the individual picture. The aim of surveillance is to detect early, precancerous ("dysplastic") changes before they could become a problem. Where such abnormal or precancerous changes are found, they can often be treated directly through the endoscope using techniques that remove or destroy the affected lining, without the need for major surgery. Lifestyle measures that reduce reflux support symptom control. Throughout, certain alarm symptoms — particularly difficulty swallowing or weight loss — are treated as warnings that need prompt assessment.

Barrett's oesophagus can be one cause of these symptoms. Each guide explains the other possible causes and the red-flag warning signs that mean you should get urgent help:
Beyond medication
Lifestyle and self-care
Measures that reduce acid reflux can help with symptoms and form part of looking after the gullet: reaching and keeping a healthy weight, eating smaller meals, avoiding eating late at night and lying down soon after eating, raising the head of the bed, cutting down on triggers such as alcohol, caffeine, fatty or spicy foods, and stopping smoking. These do not remove the need for acid-reducing medicine or for regular monitoring, but they support overall control and general health.
When to get help
When to see a doctor
If you have known Barrett's oesophagus, keep to the surveillance endoscopy appointments your specialist arranges, as these are how any early changes in the lining are picked up over time. See your GP if reflux symptoms such as heartburn are frequent, persistent or not controlled, so that treatment can be reviewed. Importantly, seek prompt medical assessment if you develop any alarm symptoms: difficulty swallowing or food sticking, pain on swallowing, unintentional weight loss, persistent vomiting, or vomiting blood or passing black, tarry stools (which can signal bleeding). These symptoms always need looking into urgently, whether or not you have Barrett's oesophagus, and should never be ignored or put down to ordinary indigestion without being checked.

Answers
Barrett's oesophagus: frequently asked questions
What medicines are used for Barrett's oesophagus?
The main medicine is a proton pump inhibitor, or PPI, which strongly reduces the amount of acid the stomach makes. This eases the reflux symptoms, such as heartburn, that underlie Barrett's oesophagus, and is used as part of managing the condition. It is important to understand that medicine is only one part of care: a PPI does not remove the need for periodic endoscopy (surveillance), which is how the lining of the gullet is monitored over time so that any early, precancerous changes can be found and treated. Where such abnormal changes are detected, they can often be treated directly through the endoscope. Your specialist decides on the right combination of medicine and monitoring for you.
Will Barrett's oesophagus turn into cancer?
For the great majority of people, no. Barrett's oesophagus does carry a slightly increased long-term risk of oesophageal cancer compared with a normal gullet lining, which is why it is taken seriously and monitored — but most people with the condition never go on to develop cancer. The purpose of regular surveillance endoscopy is to keep watch over the lining so that any early, precancerous changes can be picked up and dealt with before they could become a problem, often through treatment delivered via the endoscope itself. Keeping to your monitoring appointments, controlling reflux, and reporting any alarm symptoms promptly are the best ways to stay on top of the small risk.
Why do I need regular endoscopies if I feel fine?
Barrett's oesophagus usually causes no symptoms of its own beyond the reflux that led to it, so feeling well does not tell you what is happening to the lining of your gullet. Surveillance endoscopy exists precisely for this reason: a camera examines the gullet, and small samples may be taken, to check for early, precancerous changes that you would not be able to feel. Catching such changes early means they can often be treated through the endoscope before they ever become a serious problem. The intervals between endoscopies are decided by your specialist based on your individual situation, and keeping to them is an important part of managing the condition safely.
What symptoms should make me seek help urgently?
Certain "alarm" symptoms always need prompt medical assessment, whether or not you have Barrett's oesophagus. These include difficulty swallowing or a feeling of food sticking, pain on swallowing, unintentional weight loss, persistent vomiting, and any vomiting of blood or passing of black, tarry stools, which can be a sign of bleeding. While these do not necessarily mean something serious, they should never be ignored or simply put down to indigestion — they need to be checked without delay. If you develop any of them, contact your GP urgently, and seek emergency care if you are vomiting blood or passing black stools, as this needs assessing straight away.
