This happened to me after my resection. Are you eating yet? When I got home I think I was too ambitious with food (my boyfriend was trying to feed me up too fast) - I ate a massive bowl of soup and later that evening was sick as a dog. I was really worried about it but all it was was that my bowel couldn't cope with that amount of food - in hospital I was literally having a spoonful of soup or jelly and that was it.
Hope you feel better soon.
