Signs and Symptoms of Inflammatory Bowel Disease

The two forms of inflammatory bowel disease (IBD) -- Crohn's disease (CD) and ulcerative colitis (UC) -- have several signs and symptoms in common, but they are very different conditions. One of the main differences between CD and UC is the location of the disease. CD can affect the digestive tract anywhere between the mouth and the anus, while UC only affects the large intestine (or colon). A second important difference is that CD inflammation involves all layers of the intestinal wall and UC affects only the inner lining.

Another key difference between CD and UC is the presence of comorbid (or associated) conditions. Strictures, fistulas, and fissures tend to be more common in CD, while toxic megacolon is more common in UC. Distinguishing between the two forms of IBD can be difficult at times, but knowing the difference between the two is extremely important for treatment.
