This is my first post with this thread. I had been lactose intolerant before my total colectomy but afterwards I was much more sensitive. I can tolerate a little butter and that's it. I like salads but I noticed that some of it goes through and comes out undigested. I have gotten some help from my GI's physician assistant. I use gasless citrucil to add bulk. Otherwise I haven't got much help concerning specific foods to eat. I have to avoid anything that produces gas . I have always found that my emotions had a lot to do with my digestion and that pattern has continued. I have become extremely sensitive to oil or fat. It comes out as an oil slick and diarrhea.
