Colon resection

I am a 53 yr old female that just had a resection of my small bowel about 30 days ago.  I had my first resection over 25 years ago.  I still have diarrehea but not with the same frequency although it is waking me up 2-3 times per nite.

Is this a temporary thing while my system gets used to the resectioning or just that the parts removed are responsible for absorption which causes the frequency?  Are there some proven diets that may mitigate my situation?  Any other ideas would also be appreciated.

Thanks.
