Causes and Risk Factors
Several factors contribute to the development of diverticulitis, and recognising these can aid in prevention. Common causes include:
-
Age
The risk increases for individuals over 50 years as the intestinal walls naturally weaken with age. The prevalence rises significantly in those over 65 years old.
-
Low-Fibre Diet
Regular consumption of low-fibre foods increases pressure within the colon, leading to diverticula formation. This risk factor is particularly common in Western diets.
-
Obesity
Excess weight places additional strain on the digestive system and increases inflammation risk. A BMI over 30 particularly correlates with higher incidence.
-
Sedentary Lifestyle
Lack of regular physical activity affects bowel motility and overall digestive health. Extended periods of inactivity can worsen symptoms.
-
Smoking
Regular tobacco use weakens intestinal walls and increases inflammation risk throughout the body. Smokers often experience more severe symptoms during flare-ups.
