Why have constipation medicines like Smuth L, Vayucid, and Dulcoflex stopped working for my long-term constipation after only one week, even though I eat a high-fiber diet and walk daily, and what can I do to get lasting relief?
Laxatives like Dulcoflex (bisacodyl) can cause the bowel to become dependent or less responsive after regular use, making them stop working. Also, a high-fiber diet requires significant water intake to work; without enough fluids, fiber can actually worsen constipation. Since this is long-term, please consult a healthcare professional. They can help you safely taper off stimulant laxatives, evaluate your fluid intake, and find a sustainable plan.
