A high-fiber diet is typically used to manage which conditions?

• A. Hypertension
• B. Diabetes
• C. Constipation and irritable bowel syndrome
• D. Kidney stones

Answer: (C)

High-fiber foods increase stool bulk and add water content, which helps stools move more easily through the colon. This mechanism reduces constipation and promotes regular bowel movements. For irritable bowel syndrome, especially the constipation-predominant type, soluble fiber can help normalize stool form and reduce cramping by slowing digestion and absorbing excess fluid; many patients tolerate it better than stimulant laxatives when started gradually. While a high-fiber diet supports overall cardiovascular health and can aid glycemic control, its most direct and typical use in this context is to manage constipation and IBS, rather than primarily addressing hypertension or kidney stones.
