I was able to control some of my chronic pouchitis symptoms by eliminating refined sugar and simple carbs. I would inadvertently eat sugar, perhaps at a restaurant, and within six hours experience extensive G.I. bleeding. For some strange reason scallops also triggered bleeding. That never made sense to me. Diet only minimize the symptoms. It never eliminated the pouchitis.
A year before my J pouch was removed I developed SIBO and could somewhat control it with the low fodmap diet. It is supposed to be an elimination diet, but I was on it for the entire year, until I had the k pouch surgery.
perhaps you are already aware of this diet/ research – – it’s called breaking the vicious cycle. You can download the entire book from the Internet. The research is old, but I think it is still valuable. i’m delighted to know you are researching diet and auto immune diseases. It’s such valuable information. Hopefully doctors pay attention to it also. Janet
