Ulcerative Colitis
Ulcerative Colitis
Ulcerative colitis may be grouped with Crohn’s disease within IBD, but in many ways, they are very different conditions. This section of the Knowledge Centre describes the epidemiology and pathophysiology of ulcerative colitis, providing an overview of disease presentation and management.
In This Section
Epidemiology
What are the causes of ulcerative colitis and how many people does it affect? Within this section of the Knowledge Centre you can gain insights into the prevalence and incidence of ulcerative colitis as well as the factors that underlie the condition.
Prevalence and incidence
Ulcerative colitis is more a common presentation of IBD than Crohn’s disease (Feuerstein and Cheifitz, 2014). As with Crohn’s disease, a systematic review revealed that, worldwide, the prevalence of ulcerative colitis is highest in Europe and North America (Figure 6). The countries with the highest reported prevalence in each region were Norway and the United States, with 505 and 286 cases per 100,000 individuals, respectively (Ng et al., 2017).
Pathophysiology
What is the underlying pathophysiology of ulcerative colitis and how does it differ to Crohn’s disease? Within this section, you can gain an overview of the pathophysiology of ulcerative colitis, its presentation and disease management.
Pathogenesis
The general principles of the pathogenesis of ulcerative colitis are similar to those described for Crohn’s disease. However, there are also some important differences (Ungaro et al., 2017).
