Crohn’s disease is a form of inflammatory bowel disease that causes inflammation in the gut. It can affect the gastrointestinal tract anywhere from the mouth to the anus, although the most common area affected is the end of the small bowel (ileum). There are 4 types: Crohn’s disease, ulcerative colitis, indeterminate colitis and microscopic colitis.
Colitis is a generic term for inflammation of the large bowel (colon). The term colitis does not imply the specific cause, so you can have Crohn’s colitis, ulcerative colitis, indeterminate colitis, microscopic colitis as well as infective colitis amongst many others!
