I have Crohn 's disease and it's never occurred to me to fault my parents. It is a genetic disease, and I can only hope that the doctors you've worked with have helped you to understand the basics so you can educate yourself and help your son.

There's been a lot of really encouraging progress in the 15+ years since my diagnosis, but there are still a lot of unknowns. I got very little support in the dietary side of things other than the infamous elimination diet approach. It took a while for me to dial it in, but I did and am very rarely sick these days, now that I've discovered my own food sensitivities.

As much as you may want to solve this problem for him, it will take an immense amount of maturity on his part to want to discover and understand his limitations and to create and stick to a sustainable lifestyle.
