I have Crohn's Disease, and due to that I have had 2 bowel resections and a permanent colostomy for a total of nearly 1 meter of missing bowel. For the last 2 months I have not been able to gain any weight. I am eating plenty and my appetite is good, in fact, I'm always hungry. But I have noticed that after I eat, I will start to see it come out of my bag after about 2 and half hours. I have also been hospitalized for dehydration and kidney failure. I have tried eating more fiber, as well as a medication, but I cannot seem to gain any weight. Any suggestions?
