    Frequently Asked QuestionsUC Causes

    My parent/sibling has UC. What does that mean for my risk?

    Having a sibling or parent who has UC significantly raises your risk of developing UC yourself. In fact, about 10% to 25% of people with UC have a sibling or parent with some form of IBD, whether it be UC or Crohn's disease.

    Did I cause my UC?

    There's nothing you did or didn't do that caused you to develop UC. The cause of UC is complex and depends on many factors, from your genes to your environment.

    Is ulcerative colitis an autoimmune disease?

    Some researchers theorize that UC is an autoimmune disease because a flaw in your immune system may cause it to mistakenly attack healthy tissue in the large intestine. There’s not yet a full consensus, so we can't say definitively that UC is in fact a true autoimmune disease.

    I'm worried about getting UC. Is there anything I can do to prevent it?

    Unfortunately, there's nothing you can do to 100% guarantee you won't develop UC at some point. That said, it's always wise to practice a healthy lifestyle, including eating a healthy diet, exercising regularly, and prioritizing your mental health.
