In June 2011, I was told I had short segment barretts and my LES valve was wide open, now the barretts are gone and my LES valve is partially open. I do still struggle with reflux daily, some days more than others.
Try to eat a "clean" diet fish, turkey, chicken, lots of veggies, and stay away from all the junk foods. This will let your body try to start healing itself.
I was able to reverse my barretts over the course of about 10 months. Other than the diet changes, I felt manuka honey was the key to healing my barretts. I would drink a cup of hot water with a big tablespoon on manuka every morning and night. The price of manuka has gone up a lot in the last year but it's one thing I will never go without again.
I may not be able to cure the gerd, but I can heal the damage it does. Now it's just a game of cat and mouse with my own body.
