I was banded in Oct '07 and lost 60 lbs, taking me almost to goal. I'd had some issues with reflux pre-band but none afterwards until a couple of years post-band. I then had my fill gradually removed over several months with no luck in resolving the reflux. Due to increased hunger, I was slowly putting on the weight I'd lost, eventually regaining 30 lbs. I was diagnosed with a hiatal hernia, due to other issues, in Mar '11; in May '11, I had it repaired, along with removing and reinserting a newer, more improved (!) band.
My reflux hasn't really healed. I'd started having fills again with my new band, then unfills, again. This past May, my practitioner started me on omeprazole 20mg and gave me a fill since I was over-eating like a piggy. My reflux symptoms disappeared immediately and I've since lost 17 lbs! I have tried, a couple of times, not taking the omeprazole but would have reflux again that very night. I guess it's a trade-off. I'm not crazy about relying on prescription meds but am extremely grateful to not be hungry again and to have begun losing weight!
Regarding my new, improved band: I see a huge difference between it and my first band. I do not pb or burp as nearly as often while feeling sated much sooner, much more noticeably.
As are most of us bandsters, I am a work-in-progress. Good luck to you!
