Ulcerative colitis is an inflammatory bowel disease in which the inner lining of the large intestine and rectum become inflamed. Ulcerative colitis is characterized by diarrhea, abdominal pain and blood in the stool. The disease may vary in how much of the colon is affected, and it varies in severity as well.
Ulcerative colitis has many similarities to Crohn’s disease, another inflammatory bowel disease. They can be difficult to tell apart, although there are differences in the symptoms and the physiology of the disease.
