What kind of doctor treats Barrett Esophagus?
A gastroenterologist is a doctor who treats digestive tract problems. This specialist diagnoses and treats Barrett esophagus. A primary care doctor can spot the warning signs and refer you. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Barrett esophagus?
Barrett esophagus is a condition in which the lining of the esophagus changes. The esophagus is the tube that carries food from the mouth to the stomach. The tissue lining it becomes more like the tissue lining the intestine. This change is linked to GERD. GERD is long-term backflow of stomach acid into the esophagus. Its full name is gastroesophageal reflux disease.
People with Barrett esophagus have a higher risk of cancer of the esophagus.
Symptoms
Barrett esophagus does not cause symptoms by itself. Many people who have it also have GERD. GERD symptoms may include:
- Heartburn.
- Regurgitation, or stomach contents coming back up into the mouth.
- Chest pain or nausea.
- Problems swallowing or pain while swallowing.
- Chronic cough or hoarseness.
Some people have no warning signs at all. That is why doctors test those with long-standing GERD and other risk factors.
Causes and who gets it
Researchers do not know the exact cause of Barrett esophagus. Having GERD raises the chances of developing it. Researchers estimate about 5% to 15% of people with GERD go on to develop it.
How doctors diagnose it
Doctors most often diagnose Barrett esophagus with an upper gastrointestinal (GI) endoscopy and a biopsy. In an upper GI endoscopy, a doctor uses a thin tube with a camera to look inside the upper digestive tract. In a biopsy, the doctor takes small pieces of tissue so they can be checked under a microscope. Some doctors may also use a pill-shaped capsule device that you swallow.
Treatment
Doctors may use medicines, endoscopy, or possibly surgery. For GERD, your doctor may suggest proton pump inhibitors. These medicines are called PPIs. They lower the amount of acid the stomach makes. They can prevent further damage and, in some cases, heal damage that already exists. Some studies show PPIs may lower the chances of high-grade dysplasia, a stage of very abnormal cells, and esophageal cancer. You can buy some over the counter, or a doctor can prescribe one.
If abnormal cells are found, doctors may treat them during an endoscopy. One option is radiofrequency ablation. It uses heat on abnormal cells. Another is cryotherapy, which uses cold liquid nitrogen. A third is endoscopic mucosal resection, which cuts off and removes the changed tissue. A surgery called esophagectomy removes affected sections of the esophagus. It is less common and may not be an option for everyone.
When to see a doctor
Call 911 if you vomit blood, vomit again and again, pass out, or have chest pain that lasts two minutes or more or severe belly pain. See your doctor right away if you have trouble swallowing, weight loss without trying, or other signs of bleeding in your digestive tract.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can help you manage GERD symptoms with lifestyle changes, medicines, and other treatment. They can also help you stay on a surveillance schedule of repeat endoscopy to check for abnormal cells or cancer.
Common questions
Does Barrett esophagus cause symptoms?
No, Barrett esophagus itself does not cause symptoms. Heartburn, swallowing problems, or cough usually comes from GERD, which often goes along with it.
Can Barrett esophagus turn into cancer?
It raises the risk of esophageal cancer. If abnormal cells are found, doctors may treat them during an endoscopy.
How is it treated?
Treatment may include PPI medicines to lower stomach acid, endoscopic treatments to remove or destroy abnormal cells, or rarely surgery. Managing GERD symptoms can prevent further damage.
How is Barrett esophagus diagnosed?
Doctors most often diagnose it with an upper GI endoscopy and a biopsy. Some doctors may also use a pill-shaped capsule device that you swallow.
