Inflammatory Bowel Disease (IBD) – Crohn’s disease and ulcertative colitis

Both Crohn’s disease and ulcerative colitis are known as inflammatory bowel disease.

Inflammatory bowel disease is sometimes shortened to IBD. However, this is not the same as IBS, which is short for Irritable Bowel Syndrome, which is a very different condition.

Both these conditions can cause inflammation of the bowel (colon and rectum), with similar symptoms and treatments.

Inflammation of ulcerative colitis is usually found in the inner most lining of the bowel, while in Crohn’s disease the inflammation can spread through the whole wall of the bowel as well as affect any part of the digestive tract.

Crohn’s disease

Crohn’s disease is a long-term condition that causes inflammation in the lining of the digestive tract.

The inflammation usually occurs in the last section of the small intestine (ileum) or the colon and rectum, but any part of the digestive tract can be affected.
