Abstract

Purpose of Review

Once thought a disease of Western civilizations, the inflammatory bowel diseases (IBD) impose a global burden, now penetrating populations in Asia, Africa, and South America. We summarize similarities and differences in the epidemiology of IBD globally, highlighting gaps in knowledge where future study is needed.

Recent Findings

While incidence of IBD is stabilizing (or even decreasing) in many westernized regions, prevalence continues to grow due to a young age of onset and low mortality. In newly westernized regions, IBD is beginning to penetrate populations comparable to the rapid increases seen in North America, Europe, and Oceania in the last century.

Summary

IBD imposes a significant fiscal and resource burden on healthcare systems. As global prevalence of these diseases continues to increase, we desperately need to anticipate the future burden to proactively prepare our healthcare systems for the challenges of increased patient load and aging populations with comorbid conditions and longer disease course.
