Ulcerative colitis is a chronic inflammatory condition limited to the colon fits into the category of digestive diseases.
Ulcerative colitis shares much in common with Crohn’s disease, another form of IBD, but Crohn’s disease can affect the whole gastrointestinal tract while ulcerative colitis only attacks the large intestine, and while ulcerative colitis can be treated by performing a total removing the entire large intestine, surgery for Crohn’s disease involves removing the damaged parts of the intestine and reconnecting the healthy parts, which does not cure Crohn’s, as it can recur after surgery, mostly at the site of the intestinal anastomosis (connection) or in other areas.
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. Ulcerative colitis has an incidence of 1 to 20 cases per 100,000 individuals per year, and a prevalence of 8 to 246 per 100,000 individuals.
