I have had an ileostomy for uc since i was 7 and i'm now 27. what can i do to gain weight? i have always been under weight.

See nutritionist: Ulcerative colitis causes inflammation of the lining to the colon and the definitive treatment is removal of the colon. In many patients, there may be some short-term effect on weight, mostly related to high output and dehydration. In long-term patients, if you are unable to gain weight, you should see a nutritionist to review your caloric intake and the balance of minerals and vitamins.

Depends: When u have an ileostomy for uc no small bowel is removed and so foods are absorbed fine. Only water may be a problem. U need to be sure nothing else is preventing weight gain such as thyroid.
