Overview

Barrett’s esophagus is a change in the cellular structure of your esophagus lining. Your esophagus is the swallowing tube that carries food from your mouth to your stomach. Like all of your gastrointestinal (GI) tract, your esophagus has a protective mucous lining on the inside. But if something irritates this lining for a long time, it can damage the tissues. Sometimes, this damage actually reprograms the cells.

These changes affect the structure and appearance of your esophagus lining. To scientists, it now looks more like the lining of your intestines. They call this intestinal metaplasia. Metaplasia is when tissues in your body replace themselves with a different type of tissue that isn’t normally found there. This is a risk factor for cancer. Although the risk is small, metaplasia makes cancerous changes more likely.

How serious is Barrett’s esophagus?

Because of the small chance it might progress to esophageal cancer, healthcare providers like to keep an eye on Barrett’s esophagus. But the risk is only about half a percent per year. Cellular changes happen slowly, and metaplasia passes through another precancerous stage (dysplasia) before progressing to cancer. If your provider notices any dysplasia, they’ll remove it to stop it from progressing further.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
  • High blood pressure.
  • Diabetes.
  • Heart failure.
  • Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
  • Control high blood pressure, high cholesterol and diabetes.
  • Don't smoke or use tobacco.
  • Eat a diet that's low in salt and saturated fat.
  • Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
  • Get good sleep. Adults should aim for 7 to 9 hours daily.
  • Maintain a healthy weight.
  • Reduce and manage stress.
