Over time, chronic acid reflux can cause permanent damage to the esophagus. Blisters, ulcerations, and scarring can result in cellular changes. These changes are known as Barrett’s esophagus, a precancerous condition that, left untreated, can become malignant (cancerous).
Your doctor may order tests to be able to view the lining of your esophagus. If you have changes in the lining and are diagnosed with Barrett’s esophagus your doctor will outline a course of treatments and follow-ups.
