Diverticula usually develop when naturally weak places in your colon give way under pressure. This causes marble-sized pouches to protrude through the colon wall. Diverticulitis occurs when diverticula tear, resulting in inflammation, and in some cases, infection.
What is the main cause of diverticulosis?
A high-fat, low-fiber diet is the main culprit in diverticulosis, or the formation and periodic inflammation of out-pouchings in the intestinal wall. Genetics and low physical activity levels may also play a role.
What foods trigger diverticulitis?
Common foods such as those low in fiber or high in sugar that may increase the risk of developing diverticulosis or trigger diverticulosis symptoms include:
- Red meats.
- Processed meats.
- Fried foods.
- Full fat dairy products.
