What are the main causes of diverticulosis?

The main causes of diverticulosis include a low-fiber diet, which can lead to increased pressure in the colon as it struggles to move waste. Other contributing factors include aging, obesity, lack of physical activity, and certain medications. Genetics may also play a role, as individuals with a family history of diverticular disease are at higher risk. Overall, a combination of dietary habits and lifestyle factors significantly influences the development of diverticulosis.
