Ragtop262, I am sorry to read that your son's doctors suspect Crohn's Disease.

It is one of the Inflammatory Bowel Diseases and is a chronic condition which can not yet be cured but often can be managed. I suggest that you get a referral to a specialist gastroenterologist for your son. A gastroenterologist will be able to carry out detailed investigations and then discuss management options with him. Many of these involve anti-inflammatory medication (there are many possible options).

A significant risk factor for Crohn's Disease is bowel cancer, usually close to the Crohn's Disease lesions (a dear IRL friend of mine died from bowel cancer secondary to Crohn's Disease). Because of this, regular colonoscopic examination is recommended - the gastroenterologist will be able to discuss how frequent these should be with your son.

There is some general information about it here; http://www.mayoclinic.org/diseases-c...n/con-20032061.

All the best.
