Which intervention is effective for treating constipation?

Encouraging high-fiber foods and increasing fluid intake to 2,000 mL/day is an effective intervention for treating constipation because it addresses two key factors that contribute to healthy bowel function: dietary fiber and hydration.

High-fiber foods, such as fruits, vegetables, whole grains, and legumes, add bulk to the stool, promoting regular bowel movements and preventing constipation. Fiber increases the weight and size of the stool, making it easier to pass. Additionally, sufficient fluid intake is essential as it helps to soften the stool, further facilitating bowel movements and preventing straining.

Hydration is crucial because when fluid intake is inadequate, the colon absorbs more water from the waste material, leading to harder stools that are more difficult to pass. Therefore, combining high-fiber foods with adequate hydration creates an optimal condition for maintaining regular bowel habits and treating constipation effectively.

Other choices might suggest interventions that can worsen the condition or do not address the underlying causes of constipation adequately. For example, recommending low-fiber foods and dehydration would directly counteract the supportive effects of fiber and hydration for healthy digestion. Encouraging complete bed rest can lead to decreased physical activity, which is often associated with slowed bowel motility. Regular use of laxatives should be approached
