Hi,
After my ostomy surgery (for UC), I had very watery stool, and kept getting dehydrated, so the ostomy community said to eat "thickening foods". They were applesauce, mashed potatoes, pasta, bananas, and,oatmeal, and after months of those foods, I blimped right up, way too much, so I now just take immodium when needed, and eat a normal diet. So basically complex carbs seemed to plump me up.
Hopeso
