Re: 4 years chronic constipation post hysterectomy
You might consider a few things: 1. Enterocele (internal bowel prolapse) now that some of the pelvic support is gone since the hysterectomy. 2. Scar tissue entrapping the bowel. 3. Complications from surgical mesh that was almost certainly used during the hysterectomy (whether you were aware of it or not.)
Do some searches on all those, and more as you will almost certainly learn more. See if anything makes sense and then proceed from there.
I am sorry you are having issues. Good luck.
