Which intervention is most likely to reduce risks associated with diverticulitis?

Increasing liquid intake is an important intervention for reducing risks associated with diverticulitis because it helps maintain adequate hydration, which is essential for digestive health. Proper hydration can aid in softening stools and promoting regular bowel movements, thereby potentially decreasing the likelihood of diverticulitis flare-ups. When the stools are softer and easier to pass, the pressure within the colon is reduced, which can help prevent the formation of diverticula or the inflammation of existing diverticula.

Additionally, maintaining a well-hydrated state supports overall digestive function and can assist in preventing constipation, a condition that may exacerbate diverticular problems. This makes liquid intake a key factor in managing and reducing the risks associated with diverticulitis.

In contrast, decreasing dietary fiber may actually increase the risk of diverticulitis by leading to harder stools and constipation. Avoiding physical activity can also be counterproductive, as mild exercise is generally beneficial for digestive health. Increasing fat intake does not directly correlate with managing diverticulitis and can sometimes worsen symptoms since high-fat foods may be harder to digest. Thus, increasing liquid intake stands out as the most effective strategy among the options presented.
