14432 Barretts Esophagus

Overview

Barrett's esophagus is a condition where the tissue lining the lower part of your food pipe (esophagus) changes and starts to look like the tissue lining your intestine. This change is usually caused by long-term stomach acid reflux, often called acid reflux or heartburn. It is not cancer itself, but having it slightly raises your risk of developing a rare type of esophageal cancer.

It is fairly common. About 1 to 2 out of every 100 adults have Barrett's esophagus, though many do not know it.

It most often affects people over 50, men more than women, and those with a long history of acid reflux. It is also more common in people who are overweight or who smoke.

Symptoms

Common symptoms

• Frequent heartburn or acid regurgitation
• Difficulty swallowing or feeling food stuck
• Chest pain or discomfort
• A dry cough or hoarse voice
• Many people have no symptoms at all

Symptoms in children

• Barrett's esophagus is rare in children, but if present, they may have frequent vomiting, feeding problems, or poor weight gain.

Symptoms in older adults

• Older adults may have less obvious heartburn but can experience more difficulty swallowing, anemia, or unintended weight loss due to irritation or damage in the esophagus.

Causes

Main causes

• Long-term gastroesophageal reflux disease (GORD) — where stomach acid repeatedly flows back into the esophagus
• A weak lower esophageal sphincter, the muscle that normally keeps stomach contents down
• In some cases, no clear cause is found, and other factors like genetics may play a role

Risk factors

• Being over the age of 50
• Being male
• Having a hiatal hernia
• Obesity or excess abdominal weight
• Smoking
• A family history of Barrett's esophagus or esophageal cancer

When to see a doctor

See a doctor urgently if:

• If you have trouble swallowing, painful swallowing, or food getting stuck
• If you are vomiting blood or have dark, tarry stools
• If you have unintentional weight loss or iron deficiency anemia

Book a routine appointment if:

• If you have had persistent heartburn or acid reflux for several years and have not been evaluated
• If your heartburn symptoms have changed, become more frequent, or are not relieved by usual antacids
• If you have a family history of Barrett's esophagus or esophageal cancer

Diagnosis

Barrett's esophagus is diagnosed by an endoscopy, a procedure where a thin, flexible tube with a camera is passed down your throat to look at your food pipe and stomach. During this test, the doctor can take small tissue samples (biopsies) to check for changes.

Tests that may be done

• Upper endoscopy (also called gastroscopy)
• Biopsy — tissue samples are examined under a microscope
• Sometimes, a special dye or advanced imaging during endoscopy helps see the affected area more clearly

What to expect at your appointment

You will usually be given a sedative to make you relaxed and comfortable. The procedure takes about 15 to 20 minutes, and you can usually go home the same day. You may have a slightly sore throat afterward. The biopsy results take a few days. If Barrett's is found, your doctor will tell you the grade (how much the cells have changed) and talk about next steps.

Treatment

Treatment focuses on controlling acid reflux, preventing further damage, and monitoring for any precancerous changes. For many people, lifestyle changes and medication are enough. If the cell changes are advanced, there are procedures to remove or treat the abnormal tissue.

Self-care at home

• Maintain a healthy weight to reduce pressure on your stomach and esophagus
• Avoid eating large meals, especially late at night
• Raise the head of your bed 15–20 cm to help keep acid down while you sleep
• Stop smoking and limit alcohol, as both can worsen reflux
• Avoid foods that trigger your heartburn, such as spicy, fatty, or acidic foods

Medical treatments

Doctors often prescribe medications that reduce stomach acid, such as proton pump inhibitors (PPIs) or H2 blockers. These are not brand-specific; they work by lowering acid production. Antacids can help with occasional symptoms but do not treat the underlying condition. Always talk to your doctor about which option is right for you, and never start or stop medication on your own.

When is surgery considered?

Surgery is considered when there is high-grade dysplasia (more advanced cell changes) or early cancer. Procedures like endoscopic mucosal resection or ablation use an endoscope to remove or destroy abnormal tissue, without open surgery. Surgery to tighten the lower esophageal sphincter is rarely needed for Barrett's alone, but may be considered in severe reflux that does not respond to medication.

Living with this condition

Most people with Barrett's esophagus live full, active lives. The key is to manage your reflux and keep an eye on your health. You will likely have regular check-ups and endoscopies, usually every 2 to 3 years, to ensure the cells are not changing.

Lifestyle tips

• Eat smaller, more frequent meals
• Wait 2–3 hours after eating before lying down
• Choose lean proteins, whole grains, fruits, and vegetables
• Avoid carbonated drinks, citrus, and high-fat foods if they worsen symptoms
• Find healthy ways to manage stress, as stress can make reflux symptoms feel worse

Diet and exercise

There is no special diet that can cure Barrett's, but a diet low in acidic, spicy, and fatty foods may help reduce symptoms. Regular gentle exercise like walking or swimming can support weight management and digestive health. Avoid vigorous exercise immediately after meals, as it can trigger reflux.

Mental health and emotional wellbeing

Being diagnosed with a condition that increases cancer risk can naturally cause worry. It is normal to feel anxious or stressed. Talking to your doctor about the actual risks, which are low, can help. Your mental well-being is part of your health too, so please be kind to yourself.

Prevention

You may not be able to completely prevent Barrett's esophagus, especially if you have reflux tendencies, but you can greatly reduce your risk and slow its progression by controlling acid reflux, not smoking, maintaining a healthy weight, and eating a balanced diet.

Screening programmes

In some countries, doctors recommend a one-time endoscopy for people at higher risk, such as those over 50 with long-term acid reflux. However, screening is not routine for everyone. Ask your doctor if screening is right for you.

Complications

If left untreated

• Ongoing acid reflux can lead to inflammation and ulcers in the esophagus
• Strictures — narrowing of the esophagus that can make swallowing difficult
• Bleeding from the damaged tissue
• Progression to low-grade or high-grade dysplasia, and in rare cases, esophageal cancer

Long-term outlook

The outlook for Barrett's esophagus is generally very good. Most people do not develop cancer, and regular monitoring catches any changes early, when they are most treatable. With the right care, you can expect to live a long and healthy life.
