Crohn’s Disease is a condition that causes inflammation of the digestive system or gut. Crohn’s can affect any part of the gut, though the most common area affected is the end of the ileum (the last part of the small intestine), or the colon.
The areas of inflammation are often patchy with sections of normal gut in between. A patch of inflammation may be small, only a few centimetres, or extend quite a distance along part of the gut. As well as affecting the lining of the bowel, Crohn’s may also go deeper into the bowel wall.
Crohn’s is a chronic condition. This means that it is ongoing and life-long, although you may have periods of good health (remission), as well as times when symptoms are more active (relapses or flare-ups).
