Hi Sarah, I'm only 4 months post op. I stopped taking Omeprazole (anti acid) at Christmas and have had no signs of reflux. I can eat spicey foods and get no acid whatsoever.
I think that yes, some people get reflux post op, but I think this happens with all the main Bariatric ops. It's like when you get prescribed medication and you read the side effect list. If you thought you'd get all of those effects, you'd never take the medication. With all surgeries and medications, you get given the worst case scenario, and even if one person suffered with a symptom it gets reported.
When I met my surgeon he told me all the bad things that can happen first, and saved the best things until last.
Sorry for waffling. In summary, I don't get reflux but I do get comedy bubbles and hiccups! Lol
