I sent you a couple PMs with some info. My son has a friend (now 21) with Crohn's dx. His was severe enough to warrant surgery, but it can be controlled with proper diet, etc. and monitoring. It's harder when it's a kid because they eat everything....I hope you got the info and can pass it on. If not, let me know and I'll resend it. Good luck to your friend.
