Ask your gastroenterologist.
That being said I know a few people that have had this procedure and if they didn't give you a colostomy bag and just a pouch of intestine and rectum that lose a lot of weight.
The best thing in your condition most likely is to clean up your diet ( you have to avoid lots of fibrous foods ) and start lifting weights.
You should really consult your gastroenterologist and look for others who have had this procedure. My sister has had this for 15 years now. She lives a perfectly normal lifestyle except for having to always be aware of a restroom.
Ask your GI about the shakes.
