What is the pelvic floor? Is it the same as the pelvic diaphragm? What causes weak pelvic floor muscles? If these terms are new to you—or you already know you have issues in this area—this blog will help clear things up and guide you toward a healthier pelvic floor.
Pelvic Floor vs. Pelvic Diaphragm
Many people use these terms interchangeably, but they are not the same.
The pelvic floor is the group of muscles and ligaments lining the inside of your pelvis. These structures help with posture, stabilization, and biological breathing. The pelvic floor is made up of three parts: the pelvic diaphragm, the perineal membrane, and the deep perineal pouch.
The pelvic diaphragm is only one portion—the levator ani and coccygeus muscles. Together, these muscles form a supportive bowl that holds pelvic organs in place. In women, the pelvic floor is especially important during pregnancy. In men, it plays a key role in urinary and prostate health.
If the pelvic floor is weak, overactive, or uncoordinated, it doesn’t just affect bladder or bowel control. It also impacts posture, breathing, and the musculoskeletal system as a whole.
Why Do Pelvic Floor Muscles Weaken?
Weakness can happen in two ways: the muscles are either too tight and overworked or too inactive and underused. Both situations lead to dysfunction.
Common causes include:
- Sedentary lifestyle and poor posture
- Being overweight
- Pregnancy and delivery
- Heavy lifting or certain exercises like planks and lunges
- Running with weak stabilization
- Prostate enlargement
Like any muscle, the pelvic floor loses strength when underused. Sitting for long hours, for example, compresses the abdominal and pelvic diaphragms. This disrupts their alignment, which is key for breathing and stabilization.
For proper function, the abdominal diaphragm and pelvic diaphragm must stay parallel. Slouching or “military posture” with the chest puffed out both break this alignment. Over time, that leads to a weaker, less effective pelvic floor.
The same mechanics apply during pregnancy or when carrying extra abdominal weight. The pelvis tips forward, the lower back arches, and the diaphragms fall out of alignment. This weakens both the abdominals and pelvic floor.
The Pelvic Floor in Pregnancy and Prostate Health
For women, pregnancy puts constant downward pressure on the pelvic floor. As the baby grows, breathing and stabilization also become compromised. If forceps or a C-section are involved, muscle tissue may be damaged and require therapy afterward.
For men, an enlarged prostate creates pressure on the pelvic diaphragm and surrounding muscles. This often leads to urinary urgency and disrupts natural pelvic function.
What is Pelvic Floor Therapy?
Pelvic floor therapy can be internal or external.
- Internal therapy involves manual treatment of pelvic floor muscles through the vagina or anus. Some patients may feel uncomfortable with this, but in certain cases it is the most effective way to release tension and restore function. For men with prostate issues, internal work through the anus can reduce symptoms.
- External therapy focuses on functional rehabilitation. This may involve a physical therapist, chiropractor, or rehab specialist using exercises, movement retraining, and devices such as the Emsella chair, which stimulates rapid contractions of the pelvic floor. Tools like these can help—but they should never be the only treatment.
The key to lasting results is functional movement. No muscle in the body works in isolation. Focusing only on the pelvic floor without addressing posture, breathing, and stabilization means the problem will eventually come back.
Breathing and the Pelvic Floor
Your first breath at birth set the tone for survival—and for pelvic floor function. Breathing correctly is essential for a healthier pelvic floor.
Think of your torso as a barrel. The pelvic floor is the base, the abdominal diaphragm is the lid, and the torso muscles make up the walls. When you breathe properly, pressure is distributed evenly through this barrel, creating stability and activating the pelvic floor.
Unfortunately, many people don’t breathe this way. Instead, neck and chest muscles take over, leaving the diaphragms underused. Over time, this creates weakness, poor stabilization, and dysfunctional movement patterns.
That’s why restoring biological breathing is one of the first steps in any pelvic floor treatment plan.
Can Pelvic Floor Dysfunction Cause Lower Back Pain?
Absolutely.
When the pelvic floor and diaphragm aren’t doing their job, other muscles—like those in the lower back—step in. This compensation works for a while but eventually leads to pain, stiffness, and overuse injuries.
This doesn’t stop at the lower back. Pelvic floor dysfunction can contribute to:
- Headaches
- Shoulder and neck tension
- Hip and knee pain
- Sleep disturbances
- Lack of energy
If treatments for these issues only help short term, it may be because the pelvic floor and diaphragms were never addressed.
The Path to a Healthier Pelvic Floor
Long-term success comes from retraining the body, not just treating symptoms.
With Dynamic Neuromuscular Stabilization (DNS) and brain-based postural assessments, we can compare how your body moves today against how you once moved as a baby. Babies naturally go through stages of movement that build stability and pelvic floor strength. By revisiting those same patterns, adults can reestablish healthy movement and breathing.
A healthier pelvic floor isn’t just about Kegels. It’s about restoring the whole system—breathing, posture, and functional movement—so your body can work the way it was designed.
