Overview

Risk factors include a family history of ulcerative colitis, or Jewish ancestry. It may affect any age group, although there are peaks at ages 15 - 30 and then again at ages 50 - 70. It affects men and women equally and appears to run in families, with reports of up to 20 percent of people with ulcerative colitis having a family member or relative with ulcerative colitis or Crohn's disease. A higher incidence of ulcerative colitis is seen in Whites and people of Jewish descent.[1][2]
