Many studies have demonstrated a significant association between obesity and the risk of developing diverticulitis. In a large prospective study of 47,228 male health professionals, men with a body mass index (BMI) of at least 30 kg/m2 had a relative risk of 1.78 for diverticulitis compared with men with a BMI less than 21 kg/m2, after adjustment for other risk factors.
Dietary fiber is associated with a decreased risk for symptomatic diverticular disease. A diet high in total fat and red meat is associated with an increased risk. Current smokers appear to be at increased risk for perforated diverticulitis and a diverticular abscess, compared with nonsmokers.
