Hi and welcome to Healthcaremagic. I understand your concerns. Benefiber forms a watery gel in your digestive system. This can cause bloating, increased intestinal gas, a noisy stomach and possibly cramps. Starting off with a smaller amount and gradually increasing the dose over several weeks can help reduce these side effects. Also,benefiber bulks up and softens the stool, promoting regular and easier bowel movements. If fiber supplements are taken without sufficient fluid intake, however, they can potentially lead to or worsen constipation. I hope I have answered you query Kindly regards. Wish you a good health.
