Barrett’s Oesophagus: Symptoms, Causes and Management in the UK

Barrett’s oesophagus is a condition affecting the gullet (the tube that carries food from your mouth to your stomach). It occurs when the normal cells lining the lower part of the oesophagus are replaced by cells that look more like the lining of the intestine. This process, known as metaplasia, is usually the result of long-term exposure to stomach acid.

In the UK, it is estimated that approximately 1 in 10 people with persistent gastro-oesophageal reflux disease (GORD) will develop Barrett’s oesophagus. While the condition itself is not cancerous, the changed cells are at a higher risk of becoming precancerous (dysplasia) and eventually developing into oesophageal adenocarcinoma. Because of this, the NHS and NICE guidelines recommend regular monitoring for those diagnosed.

Interestingly, Barrett’s oesophagus itself does not typically cause specific symptoms. Instead, patients usually experience the symptoms associated with the underlying chronic acid reflux or GORD. These includes:

• Frequent heartburn: A burning sensation in the chest, often after eating or when lying down.
• Regurgitation: Stomach acid or undigested food coming back up into the throat or mouth.
• Dyspepsia: Indigestion and stomach pain.
• A bitter or sour taste: Caused by gastric fluids reaching the back of the mouth.

Some patients with Barrett's oesophagus actually report a decrease in their heartburn symptoms over time. This happens because the new intestinal-type cells are less sensitive to acid than the original oesophageal lining, which can sometimes lead to a false sense of security.

The primary driver for Barrett's oesophagus is the chronic inflammation caused by stomach acid or bile refluxing into the oesophagus. This irritation triggers the cellular changes. Several factors increase the likelihood of developing the condition:

• Long-term GORD: Having reflux symptoms for more than 5 years.
• Age: It is most commonly diagnosed in adults over the age of 50.
• Biological sex: Men are significantly more likely to develop the condition than women.
• Weight: Being overweight, particularly having a high amount of abdominal fat, increases pressure on the stomach.
• Smoking: Tobacco use is a known irritant to the digestive tract.
• Family history: A history of Barrett's or oesophageal cancer in close relatives can increase risk.

According to NICE (National Institute for Health and Care Excellence) guidance, Barrett’s oesophagus can only be definitively diagnosed through a gastroscopy (a type of endoscopy). During this procedure, a small camera is passed down the throat while the patient is sedated or under local anaesthetic spray. If the lining looks abnormal, the doctor will take a biopsy (a small tissue sample) to be examined under a microscope.

Once diagnosed, patients in the UK are typically placed on a surveillance programme. This involves having an endoscopy every 2 to 5 years, depending on the length of the affected area and the presence of any cellular changes (dysplasia). This regular check is vital for catching any early signs of cancer when it is most treatable.

Management focuses on preventing further damage by controlling acid reflux. This is usually achieved through a combination of lifestyle adjustments and medication:

Medication

Proton Pump Inhibitors (PPIs) like omeprazole or lansoprazole are the standard treatment. These medications reduce the amount of acid produced by the stomach, which helps protect the oesophageal lining.

Lifestyle Changes

• Weight Management: Reducing abdominal pressure can significantly decrease reflux frequency.
• Dietary Adjustments: Avoiding 'trigger' foods such as spicy dishes, caffeine, chocolate, and fatty foods.
• Sleep Positioning: Using a wedge pillow or raising the head of the bed can prevent acid from flowing upwards at night.
• Smoking Cessation: Quitting smoking reduces irritation and lowers overall cancer risk.

If you have struggled with persistent heartburn or acid reflux for several years, it is important to speak to a GP. While most people with reflux will not develop Barrett's, a consultation allows for an assessment of your risk factors and a potential referral for an endoscopy.

A UK online doctor can review your current medications, discuss the frequency of your symptoms, and provide medical advice on how to effectively manage GORD. If you have already been diagnosed with Barrett's, an online consultation is a convenient way to discuss your transition to surveillance or manage your PPI prescriptions. Accessing a GP online in the UK ensures you can get evidence-based advice without waiting weeks for a local appointment.
