I was diagnosed with Barretts 4 years ago; my only symptoms were nausea and a sour taste in my mouth all the time. I was told I must have had "silent GERD" for a long time. I'm now on Protonix, but still have a sour taste in my mouth alot of the time.
I have been scoped 4 times since I was diagnosed and 2 showed Barretts and 2 didn't. My doctor explained that it really depends on where the biopsies are taken, my area was fairly small so if they didn't biopsy that area, it didn't show up.
There is a procedure you can have done to burn the Barretts off. I think it's the Barrx procedure, or something like that. I actually spoke to a Dr. about it last year, but I had alot of other gastro issues, so decided to take care of them first and then look into this further.
