hi i also have the same prob, every time i eat even if a little i get really bloated nad gases, i can go weeks with out having any bowle movments,
it got so bad i had a colonic irrigation!which at the time was really good, very pianful but lady said if had nornmal bowels then it doesnt hurt at all!! but it did mean i got rid of some waste!! only prob is i didnt wnat to eat after to aviod being full againg, so whan finally ate solid food, took a week(not v sensible tho) i blow out like 8 months preg and didnt go loo for 2weeks, but none the less i had anoyther one and it was abit better, just good to feel empty for a day!!
i also use Dulco-lax to heklp movement, i tend to take abit more then reccomended but my view is my bowles are not normal so need alittle more hlep!! they do work , but be carefull took 1 too many nad couldnt loeave toliet all day!!
as for food, i have no idea what to eat yet, ive cut out dairy, im also a veggie, so eat lots of veg etc, i try to eat wheat free crackers,rice cakes and bread, but bread is my weakness nad helps reduce mt stomach acid!but still i get v bloated if i eat moer then a few mouthfuls, sorry not to b much help, if u have any new ideas let us no to!!
oh yeah my partber forced prune juice down me and that helped a little, not the nicest but wortth a go!
ive got meeting with GI doc tues will let u no what he suggets if anything, also my dietticen has given me a elemination diet that cuts out loads of food and u reintroduce them weekly to see what effects u most, am starting it after GI doc! but its v restictive, ie rice cakes, no diary, fried food, meet, wheat, yeast etc!! but will give it ago!!
sorry not tp be more help
