Why is diverticulosis more common in developed countries?

Diverticulosis is more common in developed countries primarily due to dietary factors, particularly a low-fiber diet that is prevalent in these regions. A diet lacking in fiber can lead to increased pressure in the colon, contributing to the formation of diverticula. Additionally, lifestyle factors such as sedentary behavior and obesity, which are more common in developed nations, may also play a role in the higher incidence of this condition. Overall, these factors combine to create a higher risk environment for diverticulosis in developed countries.
