What is Barrett’s esophagus?
Barrett’s esophagus is when tissue similar to intestinal lining replaces the tissue of the esophagus. Doctors call this process intestinal metaplasia.
What causes Barrett's esophagus?
While experts don’t know the exact cause of Barrett’s esophagus, some things make it more likely to develop the condition.
Gastroesophageal reflux (GERD) increases your chances of developing Barrett’s esophagus. GERD is a more serious, chronic form of recurrent heartburn, caused when stomach contents flow back up into the esophagus and damage the cells in your esophagus.
Between 5-10% of people with GERD develop Barrett’s esophagus.
Obesity – specifically high levels of belly fat – and smoking increase your chance of developing Barrett’s esophagus. Some studies suggest that your genetics may play a role in developing Barrett’s esophagus, too.
Symptoms of Barrett’s esophagus
While Barrett’s esophagus itself doesn’t cause symptoms, many people with Barrett’s esophagus have GERD, which does cause symptoms.
Barrett’s esophagus diagnosis
Doctors diagnose Barrett’s esophagus with an upper gastrointestinal (GI) endoscopy and a biopsy. The condition may also be found during testing to find the cause of GERD symptoms.
Your doctor will ask you to provide your medical history. Your doctor may also recommend testing if you have multiple factors that increase your chances of developing Barrett’s esophagus.
