Pelvic floor exercises come up regularly in conversations about bedwetting in girls — sometimes recommended by health visitors, sometimes mentioned in clinic leaflets, occasionally suggested by well-meaning relatives. But how much does the evidence actually support them? This article sets out what the research shows, what pelvic floor training can and cannot do for nocturnal enuresis, and when it might be worth exploring.
What Pelvic Floor Exercises Actually Are
The pelvic floor is a group of muscles that support the bladder, bowel and uterus. In girls and women, these muscles play a role in controlling urination — they help keep the urethra closed when the bladder is filling and relax to allow voiding. Pelvic floor exercises (sometimes called Kegel exercises) involve consciously contracting and releasing these muscles in a structured way.
They are well-established in adult continence care, particularly for stress urinary incontinence in women. The question is whether that benefit translates to childhood nocturnal enuresis — which is a meaningfully different condition.
Bedwetting vs Pelvic Floor Weakness: Not the Same Problem
Understanding what causes bedwetting matters here. Primary nocturnal enuresis — the most common form, where a child has never reliably been dry at night — is driven largely by three overlapping factors: overproduction of urine at night, a bladder that signals urgency before it is fully full, and difficulty arousing from sleep. It is not typically a failure of the muscles that hold urine in.
If you want a fuller picture of the underlying science, What Really Causes Bedwetting? A Parent’s Guide to the Science covers the physiology in plain language.
For most girls who wet the bed at night, the pelvic floor is not the weak link. The bladder may be overly reactive, the antidiuretic hormone (ADH) response overnight may be insufficient, or the arousal threshold may simply be very high. None of those are pelvic floor problems, and exercises do not address them directly.
What Does the Evidence Actually Show?
The research specifically on pelvic floor exercises for nocturnal enuresis in girls is limited and largely inconclusive when exercises are used in isolation. Most relevant studies look at pelvic floor training as part of a broader bladder rehabilitation programme — sometimes combined with biofeedback, urgency suppression techniques, and fluid management.
Where Evidence Is Stronger: Daytime Wetting and Overactive Bladder
The picture is clearer for daytime symptoms. Pelvic floor training, particularly with biofeedback, has reasonable evidence behind it for overactive bladder (OAB) and daytime urge incontinence in children. A 2014 systematic review published in the Journal of Urology found biofeedback-assisted pelvic floor training beneficial for dysfunctional voiding in children — though this was predominantly a daytime condition.
If a girl has both daytime wetting and bedwetting, addressing the daytime symptoms first (or alongside) is clinically logical, and pelvic floor training may be a reasonable part of that. My Child Is Wetting During the Day as Well: How Daytime and Nighttime Wetting Relate explores that connection.
Isolated Nocturnal Enuresis: Weaker Evidence
For purely nocturnal enuresis without daytime symptoms, pelvic floor exercises alone have not been shown to produce significant improvement. NICE guidelines on childhood nocturnal enuresis (CG111) do not include pelvic floor training as a first-line treatment. Their recommended hierarchy — after simple lifestyle measures — is enuresis alarms and desmopressin, sometimes in combination.
That does not mean exercises are harmful or pointless. It means they are unlikely to be sufficient on their own if the underlying driver is hormonal or arousal-related rather than muscular.
When Might Pelvic Floor Work Be Useful for Girls With Bedwetting?
There are specific situations where pelvic floor rehabilitation may contribute meaningfully:
- Daytime urgency alongside nighttime wetting — improving bladder control during waking hours can sometimes reduce overall bladder instability, with modest indirect benefit at night.
- Post-void dribbling or incomplete emptying — some girls have poor voiding coordination, which pelvic floor awareness training can help with.
- Dysfunctional voiding — where a child contracts rather than relaxes the pelvic floor during urination, leading to incomplete bladder emptying. This is diagnosed by a specialist, not assumed.
- As part of a structured bladder training programme — scheduled toileting, urgency suppression, and pelvic floor strengthening together have more evidence than exercises alone.
If any of these apply, a referral to a paediatric continence nurse or physiotherapist with experience in pelvic health is a reasonable next step. Your GP can make that referral.
How Pelvic Floor Exercises Are Taught to Children
Adult Kegel instructions do not translate well to children. Younger girls often need age-appropriate explanations — visualisations like “squeeze as if you are stopping a wee” or “lift a lift inside your tummy” — and benefit from guided practice rather than written instructions alone.
Biofeedback equipment (used in clinic) gives children real-time feedback on whether they are contracting the right muscles. This dramatically improves accuracy, because a significant proportion of children who think they are doing pelvic floor contractions are actually bearing down or tensing the wrong muscle groups.
Home practice is typically 10–15 contractions, two to three times per day, with both quick flicks and sustained holds. Consistency matters more than duration. Results — where they occur — generally take six to twelve weeks to become apparent.
What to Realistically Expect
If a girl is doing pelvic floor exercises for bedwetting without any daytime symptoms, the honest expectation is that exercises alone are unlikely to resolve the problem. They are not harmful to try, and awareness of the pelvic floor has general value, but it should not replace evidence-based approaches like alarm therapy or medical review.
If you are at the stage where standard approaches have not produced results, We Have Tried the Alarm, Desmopressin, Lifting and Nothing Has Worked: Next Steps may be a more practical starting point for what to explore next.

A Note on Anatomy and Gender
Girls do have a shorter urethra than boys, and the anatomy of voiding differs in relevant ways — including how pelvic floor mechanics influence continence. This is part of why daytime pelvic floor training research in children skews female. However, it does not mean bedwetting in girls is more muscular in origin than in boys. The nocturnal enuresis mechanism is similar across sexes; the relevance of pelvic floor training remains the same for both.
The Bottom Line
Pelvic floor exercises for girls with bedwetting are not backed by strong evidence when used in isolation for nighttime wetting. They have more support for daytime overactive bladder symptoms, and may be a useful component of a broader programme if a girl has mixed daytime and nighttime symptoms or a specific voiding dysfunction diagnosis.
They are worth discussing with a GP or continence nurse — particularly if daytime urgency or unusual voiding patterns are part of the picture. But they are not a substitute for a proper clinical review, and parents should feel confident asking for one rather than trying to manage this alone through exercises.
Managing bedwetting effectively often means addressing multiple factors at once, not just one. If the emotional weight of all of it is adding up, Managing Bedwetting Stress as a Family: What Really Helps is worth a read alongside the practical steps.
