Really really sick of this problem. I've had rectocele surgery so in theory I should be able to go to the loo fully.
But unless I'm desperate - imagine coming home from a walk desperate for a poo, I race to the bathroom and one press on my perineum, and everything comes out, I always always have some retained stool.
I woke up this morning needing the loo. Sit down, feet on poo stool, all relaxed. Half the poo comes out then my pelvic floor clamps shut. I press on my perineum and the poo goes back the wrong way. Say for another 5 minutes blowing into a straw, moo-ING and all the other breathing stuff. Nothing.
So now I have a sore stomach until Nature gets going again later. This really impacts my life.
My poo is very soft, always perfect softness on Bristol chart, sometimes errs towards peanut butter/cowpat consistency. I drink 8 pints water and eat well over 30g of soluble and insoluble fibre daily, sometimes more like 40g.
The problem is not movement. I am not constipated. I need the loo daily. But I can't get it all out and it's driving me to distraction.
For those who are about to suggest it, I have recently had a prolapse repair.
I raise my legs, breathe, push on my perineum. And still no luck.
