Inflammatory Bowel Disease affects various parts of the gastrointestinal tract. The parts affected depend on the form of IBD, whether it is Crohn’s Disease or Ulcerative Colitis.


Crohn’s Disease (CD) can affect any part of the gastrointestinal tract, including the mouth, stomach, intestines, and anus. Inflammation and ulcers can be present in any layer of the tissue that forms the walls of your gut.


Ulcerative Colitis (UC) affects the large intestine (or colon) and rectum. UC causes mucosal inflammation and ulcers over a wide area.
