Pelvic Floor Considerations During Pregnancy: Preparing and Preserving Pelvic Function

Pregnancy is one of the most remarkable transformations a body can experience. As your baby grows, your posture, breathing, and pelvic alignment shift to make room for new life. But with all those changes, it’s easy for the pelvic floor—the group of muscles supporting your bladder, bowel, and uterus—to become overworked, underused, or misunderstood.

Many people are told to “just do your Kegels” during pregnancy, but the truth is, pelvic floor health is far more nuanced than that. In fact, preparation during pregnancy isn’t only about strengthening—it’s about balance, coordination, and adaptability.

As a pelvic floor physical therapist, my goal is to help expecting moms understand how to preserve pelvic function through pregnancy and prepare for delivery and postpartum recovery with confidence.

Understanding the Pelvic Floor During Pregnancy

Your pelvic floor muscles act like a supportive hammock at the base of your pelvis. They provide stability, help control bladder and bowel function, and play a key role in sexual health and childbirth.

During pregnancy, these muscles are constantly adapting to new demands:

  • Increased load: The growing uterus and baby add gradual weight and pressure to the pelvic floor.
  • Hormonal changes: The hormone relaxin softens connective tissue and ligaments, allowing more flexibility—but sometimes at the expense of stability.
  • Postural shifts: As your center of gravity changes, you may develop tension in the back, hips, or inner thighs, which can alter how the pelvic floor functions.
  • Breathing pattern changes: The diaphragm and pelvic floor work together. As the uterus expands upward, breathing mechanics can change—sometimes reducing natural movement of the pelvic floor.

Together, these shifts can lead to symptoms like heaviness, leakage, pelvic or hip pain, or even constipation. But with guided awareness, most of these changes can be managed—or prevented—throughout pregnancy.

  1. Learn to Connect with Your Pelvic Floor—Both Strength and Release

Many people think of pelvic floor therapy as all about tightening or Kegels, but in reality, the ability to relax is just as important.

During pregnancy, the pelvic floor must be able to both contract and lengthen—especially to accommodate delivery. A tight, guarded pelvic floor can make childbirth or postpartum recovery more challenging.

Try practicing this connection:

  • Sit or lie comfortably and place one hand on your lower belly.
  • Take a slow breath in, imagining the air expanding downward into your ribcage and pelvis.
  • As you inhale, allow your pelvic floor to gently lengthen or “melt” downward—like a trampoline softening under weight.
  • As you exhale, gently lift and engage the muscles without clenching.

This awareness builds coordination and prepares the pelvic floor for the stretching, pressure, and recovery that come with childbirth.

  1. Support Your Posture and Core Connection

As your belly grows, your center of gravity shifts forward. This can increase pressure on the lower back, hips, and pelvic floor.

Tips for support:

  • Stay mobile: Gentle stretching and daily walking help balance tension in the hips and pelvis.
  • Practice alignment: When standing, think “ribs over pelvis” rather than arching your back. This position allows your diaphragm and pelvic floor to move in sync.
  • Incorporate functional movement: Learn to exhale with effort—like when lifting groceries, getting out of bed, or standing up—to reduce downward pressure on your pelvic floor.

A pelvic floor therapist can assess your posture, breathing, and movement patterns to help you optimize daily activities and prevent strain.

  1. Manage Pressure: Breathing and Core Strategy

One of the biggest causes of pelvic floor stress during pregnancy isn’t weakness—it’s excess intra-abdominal pressure. When you hold your breath, strain to move, or brace your core too tightly, pressure gets directed downward onto the pelvic organs.

To manage this:

  • Practice exhaling through exertion—for example, exhale gently when standing, lifting, or rolling in bed.
  • Avoid holding your breath or “bearing down.”
  • Keep your ribcage mobile with side stretches and thoracic rotation exercises to help your diaphragm function efficiently.

Breath coordination not only supports your pelvic floor but also improves oxygen flow, helps manage swelling, and prepares your body for labor.

  1. Address Constipation and Bladder Habits Early

Constipation is common during pregnancy due to hormonal shifts and slower digestion—but it can strain your pelvic floor significantly.

To prevent issues:

  • Stay well-hydrated and eat fiber-rich foods (fruits, vegetables, whole grains).
  • Use proper toilet posture: feet supported, elbows on knees, and exhale gently rather than pushing.
  • Avoid “just-in-case” urination—emptying your bladder too often can train it to signal urgency prematurely.

If you notice discomfort, incomplete emptying, or pelvic heaviness, early intervention with a pelvic floor therapist can make a big difference.

  1. Prepare for Birth and Postpartum Recovery

Pelvic floor therapy during pregnancy can help you prepare for birth with confidence. Education and guided practice may include:

  • Perineal stretching and relaxation techniques to prepare tissues for delivery.
  • Labor positioning strategies to minimize strain on the pelvic floor.
  • Pushing mechanics—learning how to coordinate breath and muscle lengthening instead of bearing down.
  • Early postpartum guidance on gentle movement, healing, and rebuilding strength safely.

The focus isn’t just on birth itself—it’s about ensuring your pelvic floor can recover well afterward, minimizing issues like leakage, prolapse, or persistent tension.

The Takeaway

Your pelvic floor deserves care and attention throughout pregnancy—not just after delivery. By learning how to balance strength, relaxation, posture, and breathing, you can protect your pelvic floor, prepare for birth, and support a smoother recovery.

Pregnancy is a time of change, but it doesn’t have to mean pain or dysfunction. With intentional movement and support, you can feel strong, confident, and connected to your body every step of the way.
