Barrett’s Oesophagus

Introduction

Barrett’s Oesophagus is a condition in which the lining of the oesophagus changes after prolonged exposure to stomach acid. It is often caused by chronic gastroesophageal reflux disease (GERD).

While not everyone with GERD develops Barrett’s Oesophagus, those with persistent reflux symptoms are at higher risk. Early detection is key, as Barrett’s Oesophagus can increase the risk of developing oesophageal cancer if left unmanaged.

Signs & Symptoms

Barrett’s Oesophagus often develops silently, with many individuals unaware they have it until diagnosed via endoscopy. However, common Barrett’s Oesophagus symptoms can include:

  • Persistent heartburn or acid reflux
  • Difficulty swallowing (dysphagia)
  • Regurgitation of stomach contents or sour taste in the mouth
  • Chest discomfort or burning behind the breastbone
  • Chronic cough, hoarseness or sore throat due to acid irritation

Symptoms may overlap with general GERD, so regular monitoring and consultation with a gastroenterologist are important, especially for those with long-standing reflux. Early recognition allows timely intervention and reduces the risk of complications.

Causes & Risk Factors

Barrett’s Oesophagus is primarily caused by repeated exposure of the oesophagus to stomach acid.

Contributing factors include:

  • Chronic GERD: Persistent reflux is the strongest risk factor
  • Age and gender: More common in men over 50
  • Obesity: Particularly abdominal obesity, which increases acid reflux
  • Smoking: Increases the risk of oesophageal changes
  • Family history: Genetics may play a role
  • Hiatal hernia: Can worsen reflux and oesophageal irritation
  • Dietary factors: Frequent consumption of spicy, fatty, or acidic foods

Diagnosis

A thorough assessment is necessary for Barrett’s oesophagus diagnosis and to determine the degree of cellular changes that may increase cancer risk.

  • Medical history review: Evaluates the presence, frequency and duration of reflux symptoms, lifestyle habits (such as smoking, alcohol intake or diet), and any history of GERD treatment.
  • Endoscopy (oesophagogastroduodenoscopy): Allows direct visualisation of the oesophageal lining. During the procedure, your gastroenterologist checks for redness, inflammation, or changes in colour and texture that may suggest Barrett’s oesophagus.
  • Biopsy: Small tissue samples are collected during endoscopy to confirm the presence of intestinal metaplasia (cells resembling those of the intestine) and assess for dysplasia, which indicates precancerous changes.
  • Imaging or pH monitoring: Tests such as ambulatory pH monitoring or impedance testing may be used to measure acid reflux exposure and evaluate oesophageal function. In certain cases, imaging such as barium swallow studies can help identify strictures or anatomical abnormalities.

Patients are usually assessed by a gastroenterologist, who will determine the extent of cellular changes and create a personalised care plan that may include surveillance, medication or endoscopic therapy. Early diagnosis enables close monitoring and intervention before progression to oesophageal cancer.

Types of Barrett’s Oesophagus

Barrett’s oesophagus can be classified based on the degree of abnormal cell development (dysplasia). Understanding the type helps guide treatment and monitoring frequency.

Non-dysplastic Barrett’s Oesophagus

  • Abnormal oesophageal lining is present but without precancerous changes.
  • Regular endoscopic surveillance is recommended to monitor progression.
  • Focus is placed on managing GERD with acid-suppressing medication, diet adjustments, and lifestyle changes such as weight management and smoking cessation.

Low-Grade Dysplasia

  • Early precancerous cell changes are detected in the oesophageal lining.
  • Requires more frequent endoscopic monitoring and may be treated with endoscopic mucosal resection or radiofrequency ablation to remove or destroy abnormal tissue.
  • Ongoing GERD management remains essential to reduce further irritation.

High-Grade Dysplasia

  • Significant precancerous cell changes are present, with a higher likelihood of developing into oesophageal adenocarcinoma.
  • Treatment may involve endoscopic resection, radiofrequency ablation, or surgical intervention (oesophagectomy), depending on the extent of involvement and the patient’s overall health.

By identifying the stage and type of Barrett’s oesophagus, specialists can provide targeted treatment and follow-up to reduce cancer risk and improve long-term outcomes.

Treatments

Treatment focuses on managing reflux, protecting the oesophagus, and preventing progression:

  • Medication: Proton pump inhibitors (PPIs) to reduce stomach acid
  • Lifestyle modifications: Weight management, dietary adjustments, avoiding smoking and alcohol
  • Endoscopic therapies:
    • Endoscopic mucosal resection for removing abnormal tissue
    • Radiofrequency ablation to destroy dysplastic cells
  • Surgery: In severe or high-risk cases, procedures such as esophagectomy may be necessary

Patients often combine medication, lifestyle changes, and monitoring to manage symptoms and prevent progression. Early and tailored intervention can significantly improve outcomes.

Complications

Without proper management, Barrett’s Oesophagus can lead to:

  • Increased risk of oesophageal adenocarcinoma
  • Chronic GERD symptoms impacting daily life
  • Strictures or narrowing of the oesophagus, causing swallowing difficulties
  • Possible nutritional deficiencies due to eating difficulties

Prevention

While not all cases are preventable, steps to reduce risk include:

  • Managing acid reflux early with medications and lifestyle adjustments
  • Maintaining a healthy weight and avoiding smoking or excessive alcohol use
  • Eating smaller meals, avoiding late-night eating and reducing trigger foods
  • Regular check-ups with a gastroenterologist, especially if symptoms persist

Living with Barrett’s Oesophagus

Daily adjustments can help manage symptoms and improve quality of life:

  • Adopt reflux-friendly habits: Eat slowly, avoid lying down immediately after meals
  • Monitor symptoms: Keep a diary of reflux triggers and episodes
  • Follow medication schedules as prescribed by your gastroenterologist
  • Attend routine endoscopic surveillance to track changes in the oesophagus lining
  • Maintain a healthy diet, manage weight and avoid smoking to reduce reflux

Navigating Barrett’s Oesophagus in Singapore

The Problem and Types of Barrett’s Oesophagus

Barrett’s Esophagus is becoming more common due to the high prevalence of gastroesophageal reflux disease (GERD). The condition develops when prolonged acid exposure damages the lining of the oesophagus, potentially leading to precancerous changes. It can range from non-dysplastic forms, which carry minimal cancer risk, to high-grade dysplasia that requires close monitoring or endoscopic treatment.

Consultation to Ongoing Care

Managing Barrett’s Oesophagus in Singapore begins with a consultation with a gastroenterologist. The doctor will review your medical history, assess your symptoms, and may recommend an endoscopy with biopsy. Based on the results, a personalised care plan may include medication, dietary changes, endoscopic procedures, or surgery in advanced cases. Patients are guided on lifestyle strategies, symptom monitoring, and scheduled surveillance endoscopies to protect long-term oesophageal health.

When to Seek Help

You should consider seeking professional help if you experience persistent heartburn, trouble swallowing, regurgitation or chest discomfort that does not improve with over-the-counter remedies. Early consultation with a gastroenterologist in Singapore ensures timely assessment, appropriate surveillance, and interventions to reduce the risk of complications such as oesophageal cancer.
