What is inflammatory bowel disease?
Inflammatory Bowel Disease is the inflammation of your intestines, where your intestines appear red, raw and irritated (see pictures below).
There are 3 types of inflammatory bowel disease:
Ulcerative Colitis, Crohns Disease, and Indeterminate Inflammatory Bowel Disease.
- In Ulcerative Colitis, the inflammation is only at your colon or large intestine. When the inflammation is limited to the last part of your colon (the rectum), it is called proctitis.
- In Crohns Disease, the inflammation can occur anywhere along your gastrointestinal tract from your mouth to your anus.
- In Indeterminate Inflammatory Bowel Disease (sometimes called Indeterminate Colitis), you may have symptoms or test results that make it difficult for doctors to put you in the Crohns Disease or Ulcerative Colitis category.
