What is Crohn’s Disease?

If you’ve just been diagnosed with Crohn’s Disease, or even if you’ve had it for years, you would likely be wondering what it is and what it means for you.

Crohn’s Disease (CD) is a form of Inflammatory Bowel Disease (IBD) that causes inflammation of your digestive tract. It can affect any part of the digestive tract, from the mouth to the anus, and often spreads into the deeper layers of the bowel. It happens when parts or all the lining of these areas becomes inflamed. This is usually a response to something foreign (such as an infection).
