I was diagnosed with IBS-C about 35 years ago. I'm 65 years old now, and I'm still struggling. I gave up on doctors many years ago. I saw many doctors, but no one helped me. I have pelvic floor dyssynergia as well. I've been told to get more fiber, but I seem to get more constipated with more fiber. So, I consulted with AI, and it suggested to switch to low residue diet with very little fiber. This method actually worked for some patients with chronic constipation. There was a study on that. I'm wondering if any of you has heard about this, or even tried it. Fiber has become like a religion over the years, and I have never doubted that actually fiber would work against me. It's difficult to switch after so many years. But I'm desperate, and I have to find a solution. I would love to hear from you.

Stopping or reducing dietary fiber intake reduces constipation and its associated symptoms
