Is there a clear indication that existing constipation can be effectively resolved by increasing the intake of dietary fiber?

• A. Yes, definitive improvement
• B. No
• C. Only in children
• D. Only with soluble fiber

Answer: (B)

Increasing dietary fiber can help some people with constipation by making stools bulkier and easier to pass, but the response is not universal. Constipation has multiple causes—slow transit, pelvic floor dysfunction, medication effects, and other medical conditions—and not all of these improve simply with more fiber. Some individuals, especially those with slow transit or those who don’t drink enough fluids with higher fiber, may see little benefit or even worsened symptoms. While soluble fiber (like psyllium) tends to be more helpful for many, there isn’t a clear, universal indication that simply increasing fiber will resolve constipation in all patients. That’s why the best answer is No.
