Answer

Annually, an estimated 700,000 physician visits and 100,000 hospitalizations are due to IBD. [30] Approximately 1-2 million people in the United States have ulcerative colitis or Crohn disease, with an incidence of 70-150 cases per 100,000 individuals. [31, 32] In persons of European descent in Olmstead County, Minnesota, the incidence of ulcerative colitis was 7.3 cases per 100,000 people per year, with a prevalence of 116 cases per 100,000 people; the incidence of Crohn disease was 5.8 cases per 100,000 people per year, with a prevalence of 133 cases per 100,000 people. [33, 34]
