I’m 6 months post revision on a 10 year old sleeve. I’m having terrible stomach problems. Dumping, cramping, nausea. I’m talking with my doctor and nutritionist about. They think it’s either diet or I’ve developed a post surgical IBS. They just put me on a two week course of Rifaximin.

I don’t know what is safe to eat any more. Everything seems to make me sick. I’ve lost 75 lbs post op 30% of my body weight in 6 months and MOST IMPORTANTLY the reflux which prompted the revision is gone.

I’m sure some of it is my own doing. One piece of candy or something with sugar (even ketchup) and I’m on the toilet. I have discovered that I need 45 min (not 30 as recommended) between eating and drinking. Anything but pure protein seems to be a problem. Salmon or chicken are ok but if I have fruit, rice, grains of any kind, and even some veggies like broccoli or zucchini I’m on the toilet in an hour.

I’m learning my portions, which are so sensitive, one bite or two too many and I’m feeling green and laying down.

I guess I’m looking for advice on how to systematically find my safe foods and portions? Has anyone else developed an IBS like condition post op such that you needed medication? I can’t tell if this is that or diet or both and I’m not happy either way.

What about trying a fodmap diet? It cuts out lots of foods know to aggravate the digestive system & then you slowly reintroduce them to see which ones don’t work for you. Your dietician should be able to give you information on it & the eating plan.

My cousin is on it for strange digestive issues. It’s not a quick process - she’s been doing it for 6 months now. I believe she went to a gastroenterologist who recommended the diet to try & identify the cause of her problem. I believe most bariatric surgeons are gastroenterologists. Mine was so maybe your surgeon is too & would be worth going back too if you haven’t (but that could just be in Australia).
