I had same problem. They really push fiber supplements which never helped me. I do try to avoid wheat products and dairy. It helps.. But IBS is malfunction of nerves in colon causing pain, nausea, general feeling of illness. Doctors don’t really know root cause. I do take ginger, and. Coconut oil (organic) as well as gas pills. Helps me a lot. Also I have rectocel from childbirth. This forms week area that catches stool and makes it difficult . I think the gas pills and coconut oil is making stool soft and passes easier. Get fiber from Cascadian Nut and fruit grain cereal daily. Lots of good natural fiber.
