What Is Barrett Esophagus?

You have Barrett esophagus. This means that there have been changes to the lining of the esophagus near the stomach. The changes have been caused by the acid reflux that occurs with GERD (gastroesophageal reflux disease). The changed lining is not cancerous. But the changes make it more likely that esophageal cancer will develop later on.

When You Have GERD

The esophagus is the tube that carries food and liquid from the mouth to the stomach. Your lower esophageal sphincter (LES) is a one-way valve at the top of the stomach. It keeps food and stomach acid from flowing backward. If the LES is weakened, food and stomach acid flow back (reflux) into your esophagus. If this happens often, the condition is called GERD.

Changes in the Lining

The stomach is kept safe from its own acid by a special lining. The esophagus isn’t meant to contact stomach acid. So it doesn’t have the special lining. With GERD, acid flows back into the esophagus often. This damages the esophagus. To protect itself, the esophagus forms a stronger lining. This is Barrett esophagus. This changed lining is not normal. It may keep changing. This is why it is more likely to become cancer in the future.

Preventing Further Damage

Your doctor may suggest regular tests to keep track of changes in the esophagus. He or she may also suggest ways for you to control GERD. This includes lifestyle changes, medication, or even surgery. This should help keep your Barrett esophagus from getting worse.

Symptoms of GERD

  • Heartburn

  • Sour-tasting fluid backing up into your mouth

  • Frequent burping or belching

  • Symptoms that get worse after you eat, bend over, or lie down

  • Coughing repeatedly to clear your throat

  • Hoarseness
