    Frequently Asked QuestionsCrohn’s Disease Causes

    I have a family history of Crohn’s disease. Can I do anything to keep myself from getting it?

    A family history doesn’t mean you will develop Crohn’s—most people don’t. Also, because there is more than one cause of the disease, it’s hard to predict who will get it. You can improve your odds of staying healthy by avoiding potential environmental triggers such as smoking and eating a highly processed diet.

    Does Crohn’s disease ever go away?

    Crohn’s disease is a chronic condition, meaning you’ll have it for life. That doesn’t mean you will always be suffering, however. Crohn’s has periods of remission—when there is no disease activity and little to no symptoms—and flares, when inflammation and symptoms return. With proper treatment, you can remain in remission for months or even years.

    I have a twin. Will he also get Crohn’s?

    The odds of that depend on whether you are identical or fraternal twins. When one identical twin develops Crohn’s, there is a one in three chance that the other twin will eventually have it as well. Fraternal twins have about the same risk of other siblings.

    Can I do anything to improve my microbiome?

    Yes! Eat a healthy and varied diet that focuses on fruits, vegetables, whole grains, fish, and healthy fats, and avoid highly processed, sugar-packed foods. Regular exercise also promotes diversity of your gut flora, as does getting enough sleep.
