Overview
Ulcerative colitis (Colitis ulcerosa, UC) is a form of inflammatory bowel disease (IBD). Ulcerative colitis is a form of colitis, a disease of the intestine, specifically the large intestine or colon, that includes characteristic ulcers, or open sores, in the colon. The main symptom of active disease is usually diarrhea mixed with blood, of gradual onset. Ulcerative colitis is, however, a systemic disease that affects many parts of the body outside the intestine. Because of the name, IBD is often confused with irritable bowel syndrome ("IBS"), a troublesome, but much less serious condition. Ulcerative colitis has similarities to Crohn's disease, another form of IBD. Ulcerative colitis is an intermittent disease, with periods of exacerbated symptoms, and periods that are relatively symptom-free. Although the symptoms of ulcerative colitis can sometimes diminish on their own, the disease usually requires treatment to go into remission.

Differentiating Ulcerative colitis from other Diseases
Ulcerative colitis should be differentiated from other causes of diarrhea. It is very important to differentiate it from Crohn's disease as the management of both conditions is different though the initial presentation may be confused for any of these disorders.[1][2]
Epidemiology and Demographics
United States, Canada, the United Kingdom, and Scandinavia have the highest incidence of inflammatory bowel disease i.e ulcerative colitis and Crohn's disease.The incidence of ulcerative colitis in North America is 10-12 cases per 100,000.[3] with highest incidences in the United States, Canada, the United Kingdom, and Scandinavia. Higher incidences are seen in northern locations compared to southern locations in Europe and the United States.[4]
Risk Factors
Risk factors include a family history of ulcerative colitis, or Jewish ancestry. It may affect any age group, although there are peaks at ages 15 - 30 and then again at ages 50 - 70. It affects men and women equally and appears to run in families, with reports of up to 20 percent of people with ulcerative colitis having a family member or relative with ulcerative colitis or Crohn's disease. A higher incidence of ulcerative colitis is seen in Whites and people of Jewish descent.
