Location of inflammation is a major factor in terms to the disease. In Crohn’s Disease, the area of the inflammation may occur anywhere in the digestive tract from mouth to anus. In Ulcerative Colitis, the large intestine (colon) is typically the only site that is affected. However, in some people with Ulcerative Colitis sections of the small intestine, and the ileum, may also show signs of inflammation.
Many symptoms of Ulcerative Colitis and Crohn’s Disease are similar, but there also are some subtle differences. Ulcerative Colitis patients tend to have pain the lower left part of the abdomen, while Crohn’s Disease patients commonly (not always) experience pain in the lower right abdomen. In the case of Ulcerative Colitis , bleeding from the rectum during bowel movements is very common, and bleeding is less common in patients with Crohn’s Disease.
Each form of Inflammatory Bowel Disease takes in the digestive tract is very distinct. Ulcerative Colitis tends to be continuous throughout the inflamed areas. In many cases, Ulcerative Colitis begins in the rectum or sigmoid colon and spreads up though the colon as the disease progresses. In Crohn’s Disease, the inflammation may occur in patches in one or more organs with in the digestive system. For example, a diseased section of colon may appear between two healthy sections.
During a colonoscopy or sigmoidoscopy, the physician can view the actual inside of the colon. With in a colon that has Crohn’s Disease activity, the colon wall may be thickened and because of the intermittent patter of diseased and healthy tissue, may have a “cobblestone” appearance. In the colon of someone with Ulcerative colitis, the colon wall is...
