Crohn disease is a chronic inflammatory bowel disease (IBD) characterized by a relapsing cycle of transmural inflammation involving any part of the gastrointestinal (GI) tract. Over time, such chronic inflammation can result in tissue damage. The prevalence and incidence of IBD is increasing worldwide, with the highest reported prevalence in Europe and North America. Peak onset is between the ages of 15 and 30 globally, with a quarter of all IBD cases diagnosed in patients under 18 years of age.

Some studies suggest a bimodal age distribution for both disorders with a possible second peak between 50 and 80 years of age. Young adults (ie, the 20- to 29-year-old age group) have the highest incidence of Crohn disease (16.6 cases per 100,000 person-years).
