I have no scientific evidence to offer, but I don’t see why it wouldn’t be possible?

As someone with pelvic floor issues, I know that the pelvic floor can affect both bowel and bladder issues. And so can stress. It seems reasonable to me that hypothetically if pelvic floor issues (spasms/tight muscles, dyssynergia—the muscles not working on a well-coordinated way, etc.) were contributing to constipation, it could also affect urination. It’s also reasonable to me that being constipated is really unpleasant and stressful and that could make it hard to urinate?

And maybe TMI, but I have occasional hours of constipation and during those times I also notice I tend to have more difficulty with urinary hesitancy (which is one of my challenges with pelvic floor dysfunction). It hasn’t been as severe as you’ve described.

I’m sorry if your doctor(s) we’re dismissive. That never feels good.

I hope that you are able to resolve or prevent both situations from happening again.
