Take someone with you, so they can help you remember every single thing your doctor says (docs tend to gloss over advice, quickly).

Also take a notebook along and write it all down. Or even record the visit (although a doctor might find this odd....).

I know nothing about Crohn's either so I don't feel at all qualified to give out advice on diet, etc.
