Hi Spooky,
My daughter has short bowel syndrome following the same surgery as your husband, although she has had more bowel removed.
I know from reading on this forum that there are people here that have found Cholestyramine (Questran) to be very successful. Sarah did try it when she was 14 but found it too unpalatable, having said that it did work for her. I think her age may have played a part in her non compliance and perhaps if she was older she would have persisted with it more. She spent 4 years planning her eating around her day because of the diarrhoea but 12 months ago happened upon natural psyllium husks and she has found these to be perfect for her, she does not suffer the side effects of cramping and bloating when she uses it.
It was trial and error but she now has it down to fine art and can now eat throughout the day when she out. I must add here that she also went to a vegan diet and very little processed food around that time too and has found that also suits her best. Sarah's nemesis is oils whether it be cooking oils or salad dressing type oils, they wreak complete and utter havoc on her!
Pop Questran into the search and you should find some older threads about it as well.
Good luck!
