1 in 3 Women develop urinary incontinence after vaginal birth. The most common preventable postpartum condition
37% Reduction in urinary incontinence risk with consistent pelvic floor muscle training, per 2024 Cochrane review
12 mo Postpartum recovery point at which pelvic floor muscle strength still has not returned to pre-pregnancy values

What actually happens to your pelvic floor in labor

The pelvic floor is a hammock of muscles and connective tissue spanning the base of the pelvis, supporting the bladder, bowel, and uterus. During vaginal delivery, these muscles stretch to several times their normal length. Unlike a leg muscle after a heavy squat, they don't spring back in six weeks.

Research tracking muscle function shows that at 12 months postpartum following an uncomplicated vaginal birth, resting vaginal pressure is 20% lower than mid-pregnancy values, and active muscle strength remains reduced. This isn't failure. It's the expected trajectory: the gap is how long and how much guidance most women receive to manage it.

Research note

The 2024 Cochrane review by Woodley and Dumoulin examined pelvic floor muscle training for preventing and treating urinary incontinence during and after pregnancy. It found moderate-certainty evidence that women who performed consistent PFMT during pregnancy were 37% less likely to develop urinary incontinence in the late postpartum period. Women who began training earlier in pregnancy had better outcomes than those who started later.

Why "do your kegels" is not a complete plan

Standard kegel advice assumes the problem is a weak pelvic floor that needs strengthening. That's true for roughly half the women who have symptoms.

The other half have a pelvic floor that is too tight (hypertonic), and adding more contraction exercises makes the symptoms worse, not better.

Symptoms of a hypertonic pelvic floor include pain during sex, difficulty emptying the bladder fully, pelvic pain, and lower back pain.

These can coexist with urinary leakage. A pelvic floor physiotherapist can identify which pattern is present and prescribe the right exercises: whether that's strengthening, relaxation, or a combination. A generic leaflet cannot.

The symptoms worth speaking up about

Many women normalize symptoms that are both common and treatable. Leaking urine when coughing, sneezing, or exercising is common. That 1 in 3 statistic is real. But common is not the same as something you have to live with permanently.

Other pelvic floor symptoms to mention to your midwife or OB-GYN: a sensation of heaviness or pressure in the vagina (which can indicate prolapse), pain during sex at any point postpartum, difficulty with bowel urgency or control, and persistent pelvic pain. These are not embarrassing. They are clinical symptoms with treatment pathways. For the broader postpartum recovery picture, see Fourth Trimester: Recovery After Birth.

Where to start

Ask your midwife, health visitor, or doctor for a referral to a pelvic floor physical therapy service at your 6-week check. In many areas you can also self-refer. Early assessment and a personalised program are significantly more effective than waiting for problems to worsen.

What pelvic floor physiotherapy involves

A pelvic floor physiotherapy assessment takes around 45–60 minutes. The physiotherapist takes a full history, assesses posture and breathing patterns (both affect pelvic floor function), and may perform an internal assessment to evaluate muscle tone, strength, and coordination. Treatment then involves personalised exercises, manual therapy if appropriate, and advice on how activities like lifting and exercise affect recovery.

Postpartum exercise return is also guided by pelvic floor readiness. High-impact exercise (running, jumping, heavy lifting) should generally be introduced gradually after 12 weeks and only once foundational strength is assessed. For new mothers managing anxiety who want to return to exercise quickly, this staged approach supports mental health and physical recovery together.

When to seek urgent assessment

See your doctor or midwife promptly if you experience: a bulge or heaviness in the vagina (possible prolapse), complete inability to control your bowel or bladder, significant pain that is not improving after the first 6–8 weeks, or pelvic pain that interferes with daily activities or sleep. These warrant prompt assessment rather than waiting for a routine postnatal check.
