Crohn’s and UC:
What are the differences?
While ongoing inflammation in the gastrointestinal (GI) tract may occur in both Crohn’s disease and ulcerative colitis, there are known differences between the two diseases.
Crohn’s can affect any part of the GI tract, from the mouth to the anus. It may appear in patches that affect some areas while leaving other sections completely untouched.
UC is limited to the colon and rectum, together known as the large intestine. The inflammation occurs only in the innermost layer of the lining of the intestine.
They are both inflammatory bowel diseases.
Both Crohn’s and UC can cause chronic inflammation—resulting in periods of being symptom-free (remission), alternating with periods of having active disease symptoms (flares).
Common symptoms associated with each condition.
The inflammation associated with Crohn’s and UC may impair the ability of affected GI tract to function properly, leading to symptoms such as persistent diarrhea, abdominal pain, and cramping.
