Welcome to the forum! So sorry to hear about the diarrhea problems you've been having. Have you been told by your GI doctor that you have short bowel syndrome? I would definitely ask your GI about this since so much of your small intestine has been removed. I do not have short bowel syndrome, but have done a little reading about it. There's some helpful info on the following website about symptoms, treatment etc. http://digestive.niddk.nih.gov/ddiseases/pubs/shortbowel/index.htm
Are you having blood tests done to check your B12 and other nutritional levels?
Keep us posted, OK?
