Ulcerative colitis is a chronic inflammatory bowel disease (IBD) that causes ulcers in the innermost lining of the colon and rectum. The colons ability to absorb water is decreased, which leads to progressive loosening of the stool, bloody stool, and sometimes cramping or abdominal pain with urgency for bowel movement (CDC, 2013; NDDIC, 2013). The exact cause or triggers of the disease are yet to be identified. Globally, the incidence of ulcerative colitis varied from 0.34 cases per 100,000 population in China to as high as 15.1 cases per 100,000 population in the UK in the 1990s (Lok et al., 2008; Shivananda et al., 1996). The diagnosed prevalence of the condition ranged between 6.3 cases per 100,000 population in China in 2006 and 243 cases per 100,000 population in the UK during 20002002 (Lok et al., 2008; Rubin et al., 2000).
