Although the etiology of ulcerative colitis is unknown, it’s thought to be related to abnormal immune response in the GI tract, possibly associated with food or bacteria such as Escherichia coli. Stress was once thought to be a cause of ulcerative colitis, but studies show that although it isn’t a cause, it does increase the severity of the attack.
Ulcerative colitis occurs primarily in young adults, especially in women. It’s also more prevalent among those of Jewish ancestry, indicating a possible familial tendency. The incidence of the disease is unknown; however, some studies indicate as many as 10 to 15 out of 100,000 persons have the disease. Onset of symptoms seems to peak between ages 15 and 30; another peak occurs between ages 50 and 70.

The term 'prevalence' of Colitis usually refers to the estimated population of people who are managing Colitis at any given time. The term 'incidence' of Colitis refers to the annual diagnosis rate, or the number of new cases of Colitis diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
