Crohns can begin from any age, I just got it really early. And taking the infected part of the intestine out is a really last chance, desperate act that I don't think they'd have actually done. Purely because Crohns, because it causes problems in your gut, can effect you anywhere between your throat to your ass, and literally taking a slice of your intestine out won't prevent it happening anywhere else. Fistula, mouth ulcers, low stomach absorbency and thus no weight gain etc. You must either have a very mild form of it, or your doctors are extremely bad doctors >.> Steroids can reduce any immediate pain anyway.
