Overview
Age and geographic distribution are two most important factors in diverticular disease presentation.
Epidemiology
The prevalence of diverticulosis is age-dependent, increasing from less than 20 percent at age 40 to 60 percent by age 60.[1][2] Western and industrialized nations have prevalence rates of 5 to 45 percent, depending upon the method of diagnosis and age of the population. Approximately 95 percent of patients in this countries have sigmoid colon Diverticlosis[3]. About 10% of the US population over the age of 40 and half over the age of 60 has diverticulosis. This disease is common in the US, Britain, Australia, Canada, and is uncommon in Asia and Africa. It is the most common cause for rectal bleeding in US adults over the age of 40 years.Approximately 95 percent of patients with diverticula have sigmoid diverticula. In Asia the diverticulosis is mostly right sided[4].
