One of the main differences between Crohn's disease and ulcerative colitis is the location of the disease. Crohn's disease can affect the digestive tract anywhere between the mouth and the anus, while ulcerative colitis only affects the large intestine (or colon). A second important difference is that in Crohn's disease, inflammation involves all layers of the intestinal wall, and ulcerative colitis affects only the inner lining. Another key difference between Crohn's disease and ulcerative colitis is the presence of comorbid (or associated) conditions. Strictures, fistulas, and fissures tend to be more common in Crohn's disease, while toxic megacolon is more common in ulcerative colitis. Distinguishing between the two forms of IBD can be difficult at times, but knowing the difference between the two is extremely important for treatment. Here you will find a list of symptoms of ulcerative colitis and symptoms of Crohn's disease.

The magnitude of the symptoms can be highly variable; one person may experience extreme diarrhea but another may cite pain as being their most problematic symptom. Because IBD is also associated with many extra-intestinal manifestations, it's important to take new symptoms seriously and get them evaluated. Something that seems small at the time could develop into a bigger problem if it's not managed properly.
