Mehmet Oz, MD, Cardiology, answeredBoth ulcerative colitis and Crohn's disease cause inflammation in the lining of the intestines and may cause similar symptoms (diarrhea, pain, cramps, and rectal bleeding, among others). But while ulcerative colitis usually occurs only in the lower part of the intestines (colon and rectum), Crohn's disease can affect any part of your digestive tract.
Lisa Ganjhu, DO, Gastroenterology, answeredBoth are inflammatory conditions of the digestive tract. Ulcerative colitis is limited to the colon and Crohn's disease can involve anywhere from the mouth to the colon.
NewYork-Presbyterian Hospital answered
Ulcerative colitis is the inflammation of the innermost lining of the large intestine and/or rectum. Crohn's disease is the inflammation of the lining and walls of the large and/or small intestine. It may also affect other parts of the digestive system and can spread deep into the tissue.
Traditionally, these two conditions were thought to be distinct types of inflammatory bowel disease (IBD). However, IBD researchers are beginning to think of IBD as a spectrum (or range) of diseases that affect the intestines.
Thus, some people may only have symptoms of ulcerative colitis or symptoms of Crohn's disease, while others may have symptoms of both conditions (known as "indeterminate colitis").
