Anyone have Crohns?

Hate to pry into anyone's personal health, but curious if anyone has this and has advice on how to cope w/ it. I have a friend w/ a young daughter who is going through this, just had some of her colon removed, it's rough.

Just at a quick glance, seems like gut biome may have some impact on this. Anyone who has this, had their bacterias measured and taken probiotic strains to improve things?

Any dietary changes that improved things?

Any things like antibiotics or chit food that make it worse?
All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.
