Postpartum Urinary Incontinence: What Actually Stops the Leaking

By Kristen Parise, BSc MSc BHScPT, Pelvic Health Physiotherapist · Founder, Blueberry Therapy Pelvic Health & Pediatrics

If you are crossing your legs when you sneeze, dribbling on the way to the bathroom, or planning your runs around the nearest washroom, I want you to know something. You are not alone. And you absolutely do not have to live like this for the rest of your life. About one in three birthing parents leak urine in the first year after delivery, and what we are learning from new research is genuinely exciting. The pelvic floor responds beautifully to training, in pregnancy and after birth, but the dose, the timing, and the supervision are everything. The old “do your Kegels and come back in six weeks” playbook is officially behind the evidence. This post walks you through what is actually happening when you leak, what we now know about preventing it during pregnancy, what to do if it is already happening, and what care actually looks like when you come into Blueberry.

Why So Many of Us Leak After Birth

Postpartum urinary incontinence does not happen because of one thing. Pregnancy is incredible, and it is also one of the biggest loads your pelvic floor will ever carry. Nine months of a growing uterus, hormones softening connective tissue, a vaginal birth or a Caesarean, and then you walk out of the hospital and immediately start lifting a car seat eighteen times a day. The pelvic floor muscles, the levator ani group, and the bladder neck are working with a completely different body than they had a year ago. When the system has not caught up to the demands you are placing on it, you leak. That is the whole story. None of it means you did something wrong, and none of it means your body has failed you. Your body just did something extraordinary. It needs structured, evidence-based rehab to catch up, the same way any other muscle group would.

What Postpartum Urinary Incontinence Actually Looks Like

There are three flavours of leaking that show up after birth. Stress incontinence is what most people think of first. You laugh, sneeze, cough, lift, jump, or run, and a bit of urine escapes. Urge incontinence is the panic dash. You hear running water or you put your key in the front door and suddenly you cannot make it in time. Mixed incontinence is having both, which is incredibly common postpartum. About a third of birthing parents experience some version of this in the first year, and a meaningful number keep leaking years later if nothing changes. Leaking is your bladder and pladder pelvic floor not coordinating the way they used to. Common, yes. Permanent, no.

The Prevention Piece: Pelvic Floor Training in Pregnancy

Here is the part most people never get told. You can start working on this before baby arrives, and the science is solid. A 2024 systematic review and meta-analysis by Zhang and colleagues in Acta Obstetricia et Gynecologica Scandinavica pooled 30 randomized controlled trials covering 6,691 pregnant people across 14 countries. The headline finding was a 28% reduction in the risk of urinary incontinence in those who did pelvic floor muscle training during pregnancy compared to those who did not (RR 0.72, 95% CI 0.59 to 0.87, p<0.0005). The same review also found PFMT reduced the risk of third and fourth degree perineal tears.

What this means in real life. If you are pregnant right now, working with a pelvic health physiotherapist in your second or third trimester is one of the smartest things you can do for your postpartum body. We teach you how to find your pelvic floor, how to lengthen it (which matters enormously for delivery), how to coordinate breath with movement, and how to start retraining strength while baby is still on board. The 2025 Canadian Postpartum Exercise and Sleep Guidelines explicitly support this, and we go deeper on the prenatal piece in Episode 66 of The Hole Shebang Podcast with Dr. Margie Davenport, the lead researcher behind those guidelines.

Starting Early After Birth Matters Just as Much

If you are reading this and you already had your baby, do not panic. Earlier is better, but later is still incredibly effective. A 2024 randomized controlled trial of postnatal women who started supervised pelvic floor muscle training within 48 hours of vaginal delivery found that by six weeks postpartum, only 11.4% of the trained group reported urinary incontinence compared to 44.1% in the standard-care group (p=0.002). That is a 4-fold difference. The same study showed a meaningful drop in symptom severity on the validated ICIQ-UI SF questionnaire. Translation: you do not have to wait six weeks to get going. Gentle, well-coached pelvic floor activation can start almost immediately, and the people who start early do dramatically better. Whether you are three days postpartum or three years postpartum, the moment you start is the right moment.

What the Newest Postpartum Meta-Analysis Tells Us

If prevention did not happen and you are now leaking, the good news is that pelvic floor muscle training works after birth too. A brand new 2026 meta-analysis by Chen and Zhang in the International Urogynecology Journal pooled 19 randomized controlled trials and showed clear, statistically significant improvements in pelvic floor muscle strength (SMD 0.61, 95% CI 0.10 to 1.12) and endurance (SMD 0.68, 95% CI 0.06 to 1.30) when people completed a PFMT program. The interesting part was in the subgroup analysis. Supervised programs lasting more than 8 weeks produced the biggest strength gains. Short, unsupervised, low-dose programs simply did not move the needle the same way. The pooled data did not reach significance on incontinence incidence overall, and the authors were honest about why. Too many of the included trials used short, low-supervision protocols. Dose matters. Supervision matters. Structure matters. Every single one of those findings lines up with what we see in clinic every week.

Why a Quick Kegel Handout Was Never Going to Cut It

The single biggest reason postpartum urinary incontinence is still showing up five and ten years after birth is that most people were handed a one-page sheet at their six-week check, told to do their Kegels, and sent home. The new research is direct about this. Supervised programs of at least 8 weeks are where the real strength change happens. On The Hole Shebang Podcast, Dr. Margie Davenport told me her team scrapped the rigid six-week postpartum checkup from the 2025 Canadian Postpartum Exercise and Sleep Guidelines and replaced it with a self-screening tool called the Get Active Questionnaire for Postpartum. The new guidelines explicitly flag pelvic floor dysfunction as a barrier that needs to be screened and treated, not waved through and forgotten. There is no magic milestone at six weeks. There is your body, and there is a pelvic floor that needs to be coached.

What Care Actually Looks Like at Blueberry

When you book a pelvic health assessment with our team, we start with a conversation. Your birth, your symptoms, your goals, what your day looks like, what you have already tried. With your full consent, we do an internal pelvic floor exam to see what is actually happening down there. Is the pelvic floor weak. Is it too tight. Is it weak AND tight. Is the coordination off. Is there scar tissue from a tear or a Caesarean that is changing how the tissues move. Without looking, we are guessing, and guessing is not why you came in.

From there, we build you a supervised, progressive program. For most of our postpartum patients, that looks like 8 to 12 visits over 2 to 4 months, with technique coaching, breathwork, real-world integration into the lifting, running, and chasing-a-toddler version of your life, and homework you actually have time to do as a new parent. We use biofeedback when it adds value, hands-on manual therapy when there is restriction to address, and the kind of evidence-based dosing the latest meta-analyses tell us actually delivers results. The goal is not to make you do Kegels forever. The goal is to retrain your pelvic floor so it does its job without you having to think about it.

When to Book a Pelvic Health Assessment

Three signs you do not need to wait another week. You leak when you cough, sneeze, laugh, lift, jump, or run. You feel urgency or you are mapping your day around bathrooms. You feel heaviness, pressure, or a “something is falling out” sensation in your vagina. Any one of those is reason enough to come see us. You do not need a referral. You do not need to be cleared by anyone. You do not need to wait until six weeks, six months, or six years. We work alongside your midwife, OB, family doctor, and lactation consultant, and we are very used to working with bodies that are still healing.

The Bottom Line

Postpartum urinary incontinence is common, and it is absolutely treatable. The newest evidence is clear on three things. Pelvic floor training during pregnancy cuts the risk of postpartum leaking by about a third. Starting supervised training in the early postpartum window dramatically reduces incontinence rates by six weeks. And for those of us who are already leaking, supervised pelvic floor physiotherapy of 8 weeks or more is what produces real, lasting change.

FAQ

Can I prevent postpartum incontinence before I even give birth?

Yes, and the evidence is excellent. The 2024 Zhang meta-analysis of 30 randomized trials and 6,691 pregnant participants found that pelvic floor muscle training during pregnancy reduced the risk of urinary incontinence by 28% (RR 0.72, 95% CI 0.59 to 0.87, p<0.0005), and also reduced the risk of severe perineal tears. We see pregnant patients in clinic every week for exactly this reason. We teach you how to find your pelvic floor, how to lengthen it for delivery, and how to start retraining strength in pregnancy so your postpartum recovery has a real head start.

Is it normal to leak urine after having a baby?

Common is not the same as normal, and it is definitely not permanent. About one in three birthing parents leak in the first year postpartum, so yes, it happens often. That does not mean you have to live with it. The 2026 Chen and Zhang meta-analysis in the International Urogynecology Journal confirms that supervised pelvic floor muscle training improves pelvic floor strength and endurance after birth. Leaking is your bladder and pelvic floor not coordinating yet, and that is something we can absolutely retrain.

How soon after birth can I start pelvic floor work?

Almost immediately, and starting early seems to make a real difference. A 2024 randomized controlled trial of postnatal women who began supervised pelvic floor muscle training within 48 hours of delivery found that by 6 weeks postpartum, only 11.4% reported leaking compared to 44.1% of those getting standard care. Dr. Margie Davenport’s team has already moved past the rigid six-week postpartum check in the 2025 Canadian guidelines. Gentle activation, breath, and connection work can start in the first days. Higher-load training scales up over time, supervised by your physiotherapist.

Are Kegels alone enough to stop leaking after birth?

For most people, no. The 2026 Chen and Zhang meta-analysis found that the strongest results came from supervised programs of more than 8 weeks, not short or unsupervised handouts. Up to half of people doing Kegels from a paper sheet are doing them wrong, and many postpartum pelvic floors are already too tight, which means more squeezing makes the leaking worse. A pelvic health physiotherapist looks at what is actually happening before prescribing strength, release, coordination work, or some combination of the three.

How many weeks of pelvic floor physiotherapy do I need?

The 2026 meta-analysis was clear that supervised programs of more than 8 weeks produce the biggest strength gains. In clinic, most of our postpartum patients come for 8 to 12 visits across 2 to 4 months. People returning to high-impact sport or recovering from a complicated birth often need longer. The dose is individualized, and we build it around your symptoms, your goals, and the life you are actually living with a baby in the house.

Can I treat postpartum incontinence without doing an internal exam?

You can, and the internal assessment is always optional and fully consented at Blueberry. That said, the international gold standard for assessing the pelvic floor is an internal exam, because it is the only way to objectively measure strength, endurance, coordination, and resting tone. Without looking, we are guessing. If an internal exam is not right for you on the day, your physiotherapist will use external assessment, real-time ultrasound where available, biofeedback, and detailed symptom tracking. You stay in charge of every step.
