If you’ve ever felt like you need to have a bowel movement but just can’t quite make it happen, you’re not alone—and you’re not imagining it.

One often-overlooked cause of chronic constipation is something called pelvic floor dyssynergia. It sounds complicated, but the concept is actually pretty simple once you break it down.

First, what is the pelvic floor?

The pelvic floor is a group of muscles that sit at the bottom of your pelvis, kind of like a hammock. These muscles support your pelvic organs—including the rectum, bladder, and uterus or prostate.

But support is only part of their job.

Your pelvic floor muscles are also responsible for:

  • Helping you hold in urine and stool

  • Relaxing when it’s time to empty your bowels or bladder

  • Coordinating with your abdominal muscles during a bowel movement

You don’t usually have to think about these muscles—they’re designed to work automatically in the background.

So… what is pelvic floor dyssynergia?

Let’s talk about how a bowel movement is supposed to work.

Normally, your body performs a coordinated sequence:

  1. Your abdominal muscles gently push

  2. Your rectum contracts

  3. Your pelvic floor muscles relax to let stool pass

In pelvic floor dyssynergia, that last step doesn’t happen correctly. Instead of relaxing, the pelvic floor muscles may tighten—or just not coordinate well—making it difficult to pass stool.

In plain English: your body is trying to go, but the “exit door” isn’t opening the way it should.

Why this matters

Pelvic floor dyssynergia is more common than many people realize and can play a major role in chronic constipation.

This can show up as:

  • Ongoing constipation despite fiber, hydration, or medications

  • Excessive straining

  • A feeling of incomplete emptying

  • Needing to shift positions or use manual assistance

  • Pelvic or rectal discomfort

This is important because not all constipation starts in the gut. Sometimes, the issue is more about coordination at the very end of the process.

Why does this happen?

There isn’t always a single clear cause. Some people develop it after:

  • Pregnancy or pelvic injury

  • Chronic straining over time

  • Surgery or trauma

  • Sometimes, no obvious reason at all

At its core, it’s a pattern your body has learned—often without you realizing it.

The good news: it’s treatable

The encouraging news is that this condition is very treatable.

Pelvic floor physical therapy focuses on helping you relearn how to properly relax and coordinate these muscles during a bowel movement. Treatment may include guided exercises, breathing techniques, and strategies to improve bowel habits and positioning.

With the right approach, many people experience significant improvement in their symptoms.

A final thought

Constipation isn’t always about what you’re eating or how fast your gut moves. Sometimes, it’s about how your body coordinates the final step.

And when that step improves, everything else can start to fall into place.
