I was diagnosed with BE about five years ago. My doctor prescribed pantoprazole which I took daily for at least a year. My own research found that melatonin has a beneficial effect on the esophagus, so I started taking 10 mg a day at night. I had a follow-up endoscopy about a year after my initial diagnosis, and the BE was gone. My doctor was very surprised. I can’t say with any certainty that the melatonin was the cause, but I still take it every night and no longer take the pantoprazole. You might research melatonin and esophagus and see what you find.
