This is the first time I have heard of short bowel syndrome.  I did see some articles about it.  Just google short bowel syndrome and j-pouch.  It brought up some discussions on the j-pouch group forum.  I had the 3 step procedure and had 2 ileostomies (an end and a loop) over a 9 month period.  I think I was probably more fatigued during the first few weeks or so.  I made sure I ate 3 meals and snacks in between, kept hydrated and still do and went for walks when I felt up to it.  Hope things go well with upcoming surgeries!

SInce the loop ileostomy interrupts the fecal stream before it gets through the entire small intestine, some folks can experience effects from the shorter bowel. The full length (minus a little bit at the end used to construct the pouch) is restored at takedown. So the effect, if any, is temporary.
