Pelvic Floor Dysfunction & Endometriosis: The Connection Many People Miss

Living with endometriosis is often described as “more than just pelvic pain.” For many people, even after surgery, medication, or lifestyle changes, symptoms like pressure, pain with movement, bladder urgency, constipation, or pain during intimacy can continue.

One major, and often overlooked, reason for this is pelvic floor dysfunction.

What Is the Pelvic Floor?

The pelvic floor is a group of muscles that act like a supportive hammock at the bottom of your pelvis.

These muscles:

• Support the bladder, uterus, and bowel

• Help control urination and bowel movements

• Stabilize the core and hips

• Play a role in sexual function

  
  

  Work with breathing and posture When these muscles are working properly, they contract and relax automatically. But with chronic pain conditions like endometriosis, they can become tight, guarded, weak, or uncoordinated.

  
  

How Endometriosis Impacts

the Pelvic Floor

Endometriosis is an inflammatory disease. It causes pain signals to fire repeatedly over months or years — sometimes long before diagnosis (which we know can take 7–10+ years on average).

The body responds to chronic pain by protecting itself.

This protection looks like:

• Constant muscle tightening (like bracing without realizing it)

• Reduced blood flow to the muscles

• Increased nerve sensitivity

• Loss of normal relaxation patterns

• “Learned pain” — the nervous system stays on high alert

Over time, the pelvic floor essentially forgets how to relax.

This is not something you can “stretch out” on your own. It’s a neurological and muscular response to chronic disease.

Signs You May Have Pelvic Floor Dysfunction (Alongside Endometriosis)

Many people assume their symptoms are just endometriosis, when in fact they are dealing with two overlapping conditions.

Common signs include:

• Persistent pelvic pain even after excision surgery

• Pain with sitting for long periods

• Pain during or after intimacy

• Difficulty starting urine flow or feeling like you can’t fully empty

• Constipation or straining despite diet changes

• Tailbone, hip, or lower back pain

• Feeling of heaviness or pressure in the pelvis

• Pain with tampon use or pelvic exams

• Pain that worsens with stress or fatigue

If this sounds familiar, you are not alone. Pelvic floor dysfunction is extremely common in people living with endometriosis.

Why It Often Goes Undiagnosed

Pelvic floor dysfunction is frequently missed because:

• Imaging does not show it

• Standard gynecologic exams may not assess muscle function

• Pain gets attributed solely to endometriosis lesions

• Many healthcare providers are not trained to evaluate pelvic floor tension

• Patients are told to “just do Kegels” (which can actually worsen symptoms)

Important note:

Strengthening exercises without relaxation training can increase pain.

The Nervous System Connection

Endometriosis doesn’t just affect organs — it affects how the brain and body communicate.

This process is called central sensitization, where the nervous system becomes hypersensitive after long-term inflammation and pain.

The pelvic floor becomes part of this loop:

Pain → Muscle Guarding → Reduced Movement → More Pain → More Guarding

Breaking this cycle requires treating the muscles and the nervous system, not just the disease.

How Pelvic Floor Physiotherapy Helps

Pelvic floor physiotherapy is one of the most evidence-supported treatments for endometriosis-related pain.

It focuses on:

1. Teaching the Muscles to Relax Again

Gentle internal and external techniques help release chronic tension safely.

2. Restoring Coordination

Learning how to contract and relax at the right time (not just strengthening).

3. Improving Blood Flow & Tissue Health

This supports healing and reduces inflammation-driven discomfort.

4. Re-training the Brain–Body Connection

Breathing, movement, and nervous system regulation calm pain signaling.

5. Addressing Whole-Body Compensation

Endometriosis often changes how you walk, sit, and move — therapy helps reset these patterns.

What Treatment Is Not

Pelvic floor therapy is not:

• Just doing Kegels

• A quick fix

• Only for postpartum patients

• “All in your head”

• Replacing surgical or medical care

It is part of a multidisciplinary approach, alongside excision surgery when needed, pain management, nutrition, and mental health support.

Why This Matters for the Endometriosis Community

At Endometriosis Canada, we hear this story often:

“My surgery was successful… but I still hurt.”

That does not mean treatment failed.

It often means the muscular and nervous system components were never addressed.

Recognizing pelvic floor dysfunction gives patients another pathway to relief, and validation that their pain has multiple layers.

What You Can Do If This Sounds Like You

• Ask your doctor for referral to a pelvic floor physiotherapist experienced in chronic pelvic pain

• Avoid starting strengthening programs without assessment

• Track symptoms like bowel, bladder, and movement pain, not just cycle pain

• Remember healing is not linear when the nervous system is involved

• Seek care providers who understand endometriosis as a full-body condition

The Takeaway

Endometriosis is not only a disease of misplaced tissue — it is a condition that reshapes muscles, nerves, and how the body protects itself from pain.

Pelvic floor dysfunction is not a separate issue.

For many patients, it is part of the endometriosis story, and an important piece of recovery.

Understanding this connection can open doors to treatments that finally address the pain that surgery or medication alone could not resolve.
