Ulcerative colitis affects about the same number of women and men. Risk factors may include:
Age: Ulcerative colitis usually begins before the age of 30. But it can occur at any age, and some people may not develop the disease until after age 60.
Race or ethnicity: Although whites have the highest risk of the disease, it can occur in any race. If you're of Ashkenazi Jewish descent, your risk is even higher.
Family history: You're at higher risk if you have a close relative, such as a parent, sibling or child, with the disease.
Complications:
Possible complications of ulcerative colitis include:
• Severe bleeding
• A hole in the colon (perforated colon)
• Severe dehydration
• Bone loss (osteoporosis)
• Inflammation of your skin, joints and eyes
• An increased risk of colon cancer
• A rapidly swelling colon (toxic megacolon)
• Increased risk of blood clots in veins and arteries
