Hi Tori, I've been pre-diabetic before, not diabetic, but I truly believe that sugar is bad for j-pouchers. I definitely noticed that sugar and gluten make me go to the bathroom more often and give me bloating.
Yeah, food choices matter. I can eat pretty much whatever I like, but I am vegetarian, so that obviously directs my choices. If you are pre-diabetic, I’m assuming you mean T2D? T2D is a metabolic condition. T1D (which I have) is an autoimmune issue, which is why I assume it is somewhat linked to my pouchitis. (I find that my pouchitis gives me no trouble is my T1D is behaving. Yay!) Stay strong!
