I don't know exactly what is wrong with my sons gut. The doctors say it is (I forget but it is stretched bowel due to constipation and resulting lack of sensation and soiling). They say he will grow out of it and it is getting better. Also there is probably a hereditary component on his fathers side.
That said, it seems to be worse if he eat gluten, and if he eats too much not great food (at birthday parties), blue food colouring is odd too. I think he just has a sensitive gut which is easily overwhelmed by some foods and stress.
Has Hirschprung's disease been ruled out? I know of kids with similar symptoms who had short-segment Hirschprung's and were diagnosed very late. It is rare but might be worth considering.
