Overview
Risk factors for diverticulosis include low intake of dietary fiber, high intake of fat and red meat, and obesity.
Risk Factors
Risk factors for diverticulosis include the following:
- Diet
- Fiber: The role of fiber in the development of diverticulosis is unclear. Several early studies suggested that low dietary fiber predisposes to the development of diverticular disease, but other studies have been conflicting.[1] However, dietary fiber and a vegetarian diet may reduce the incidence of symptomatic diverticular disease by decreasing intestinal inflammation and altering the intestinal microbiota.[2]
- Fat and red meat: The risk of diverticular disease is significantly increased with diets that are low in fiber and are high in total fat or red meat as compared with diets that are low in both fiber and total fat or red meat.[2]
- Seeds and nuts: Nut, corn, and popcorn consumption are not associated with an increase in risk of diverticulosis,diverticulitis or diverticular bleeding.[3]
- Physical activity
- It is unclear if lack of vigorous exercise is a risk factor for diverticular disease. However, vigorous physical activity appears to reduce the risk of diverticulitis and diverticular bleeding.[4]
- Obesity
- It has been associated with an increase in risk of both diverticulitis and diverticular bleeding.[5]
