15 days of vomiting and diarrhea came back as crohn's after blood test and x rays. is this normal in a 6 yr old? yes, family history.

Sorry to hear that.: About 20% of crohn's begins in children and the disease does run in families. Most cases present a bit early but it happens. I hope his course of illness is a milder one.

Not quite: Crohn's disease can be suspected from other tests but only can be diagnosed by colonoscopy and biopsy.

Possibly: A 6 year old can develop crohn's disease. Crohn's is uncommon at this age, but it does occur. But this cannot be definitively diagnosed with blood tests and x-rays. A pediatric gastroenterologist should evaluate your child. Endoscopy/colonoscopy with biopsies is the way to determine if the diagnosis is crohn's disease.
