Low back pain is one of the most common complaints we hear in the clinic. Most people assume it’s related to posture, muscle strain, or lifting mechanics and while those are certainly important factors, they’re not the whole story.
For many women, persistent or unexplained low back pain can actually be a sign of pelvic organ prolapse (POP)
What Is Pelvic Organ Prolapse?
Pelvic organ prolapse occurs when the muscles and connective tissues that support the pelvic organs such as the bladder, uterus, or rectum become weakened or stretched. This allows one or more of these organs to shift downward, creating pressure within the pelvic cavity.
While prolapse is often associated with symptoms like:
- A feeling of heaviness or pressure in the pelvis
- A bulge in the vaginal canal
- Bladder or bowel changes
…it can also present in less obvious ways like low back pain.
How Are the Pelvic Floor and Low Back Connected?
Your pelvic floor doesn’t work in isolation. It’s part of a deep core system, often referred to as the “core canister,” which includes:
- The diaphragm (top)
- The abdominal muscles (front and sides)
- The back muscles (including the lumbar spine stabilizers)
- The pelvic floor (bottom)
When everything is functioning well, these systems coordinate to manage pressure and stabilize your spine.
However, when the pelvic floor becomes weak, overstretched, or poorly coordinated as is often the case with prolapse it disrupts this entire system.
Why Prolapse Can Cause Low Back Pain
Here are a few key reasons:
1. Increased Pressure and Load on the Spine
When pelvic organs descend, it changes how pressure is distributed through your core. Instead of being well-managed, pressure can shift backward, placing additional strain on the lumbar spine.
2. Altered Posture and Movement Patterns
Many individuals with prolapse subconsciously adjust how they stand, sit, and move to avoid discomfort. These compensations often lead to increased tension in the low back muscles.
3. Decreased Core Support
If the pelvic floor isn’t providing adequate support, the rest of the core system has to compensate. This often results in overuse of the back muscles, leading to pain and fatigue.
4. Fascial and Ligamentous Strain
The pelvic organs are supported by a network of ligaments and fascia that connect into the spine and pelvis. When prolapse occurs, these structures can become strained, referring discomfort into the low back.
Signs Your Low Back Pain May Be Related to Prolapse
Low back pain linked to pelvic organ prolapse often presents alongside other subtle symptoms, such as:
- A sense of heaviness or dragging in the pelvis (especially at the end of the day)
- Symptoms that worsen with prolonged standing, lifting, or exercise
- Relief when lying down
- Changes in bladder or bowel habits
- Feeling like your core is “weak” or unsupported
If you’re noticing a combination of these symptoms, it’s worth being evaluated by a pelvic floor physical therapist.
How Pelvic Floor Physical Therapy Can Help
At Legacy Physical Therapy, we take a whole-body, root-cause approach to both low back pain and pelvic health.
Treatment is not just about doing Kegels—it’s about restoring proper coordination and support throughout your entire system.
A pelvic PT evaluation may include:
- Assessment of posture, breathing, and movement patterns
- Core strength and coordination testing
- Pelvic floor muscle assessment (strength, endurance, and relaxation)
- Evaluation for prolapse and pressure management strategies
From there, your treatment plan may include:
1. Pressure Management Training
Learning how to properly coordinate your diaphragm, core, and pelvic floor to reduce strain on both the pelvis and low back.
2. Targeted Strengthening (When Appropriate)
Not all pelvic floors need strengthening—but when they do, exercises are tailored specifically to your needs and integrated with your full core system.
3. Relaxation and Downtraining
In some cases, the pelvic floor is actually overactive and needs to learn how to relax to improve symptoms.
4. Functional Movement Training
Helping you return to lifting, exercising, and daily activities without increasing pressure or pain.
Low back pain is not always just a “back problem.” If you’ve been dealing with persistent low back discomfort especially alongside pelvic symptoms it may be your body signaling a deeper issue like pelvic organ prolapse. Pelvic floor physical therapy offers a proactive, effective approach to: Reduce pain, Improve support & Restore confidence in your body. Schedule a FREE discovery session to see how we can help!
