Inflammatory bowel disease
Crohn's disease, also called regional enteritis, is a chronic inflammation of the intestines. It is most common in the ileum or lower portion of the small intestine but may occur anywhere in the intestinal tract. Ulcerative colitis is a similar inflammation of the colon, or large intestine. IBD (inflammatory bowel disease) has been linked with an increased risk of colorectal cancer.
