I have had IBS D since I was 22 and I am now 40. This past fall I had it kick in again pretty badly. I lost 10 pounds in 3 weeks and I only weighed 110 to begin with. I have always been small so losing weight is the last thing I want. After seeing a GI dr. and getting tests run just to be sure, it resulted in the same old IBS D. My dr admitted to not knowing a lot about what to eat and referred me to a nutritionist. I can't eat dairy and I have a little trouble with wheat. Some of the things on your list would literally kill my stomach. I can't eat "roughage" at all! I am trying to eat rice based products to avoid the wheat and see if I feel better. It actually has helped. I eat rice bread, cream of rice cereal and I mix rice protein powder and rice milk in this to get those extra protein and calcium I need. The nutritionist said it would be a slow process for me to gain, but the protein was really important. It is frustrating, b/c I get on the scales hoping to see my weight go up, but I just maintain. I try not to get stressed b/c that only makes the IBS worse. Everyone on this site that has given me advice say the same things my nutritionist has said. People who have never suffered like us seem to always want to push trigger foods at you. I have a cousin who kept thinking I just didn't want to eat! He kept saying I should be eating lots of burgers and shakes, etc. I said I will lose weight if I eat stuff like that, not gain!!!! Hang in there. Really try to get your parents to get on this site or at least get a nutritionist's advice. Trigger foods will just keep making it worse and you will keep losing. Good luck. I get down about it too, but you have to keep positive and take it one step at a time.
