Pelvic floor exercises frequently come up in discussions about bedwetting in girls—sometimes recommended by health visitors, mentioned in clinic leaflets, or suggested by well-meaning relatives. But how much does the evidence actually support them? This article reviews what research shows about pelvic floor training, what it can and cannot do for nocturnal enuresis, and when it might be worth exploring.
## What Pelvic Floor Exercises Are
The pelvic floor is a group of muscles supporting the bladder, bowel, and uterus. In girls and women, these muscles help control urination—they keep the urethra closed when the bladder fills and relax to allow voiding. Pelvic floor exercises (often called Kegel exercises) involve consciously contracting and releasing these muscles in a structured way.
They are well-established in adult continence care, especially for stress urinary incontinence in women. However, whether that benefit applies to childhood nocturnal enuresis—a different condition—is less clear.
## Bedwetting vs. Pelvic Floor Weakness: Not the Same Issue
Understanding what causes bedwetting is important. Primary nocturnal enuresis—the most common form where a child has never reliably been dry at night—is driven mainly by three factors: overproduction of urine at night, a bladder that signals urgency before it is full, and difficulty arousing from sleep. It is not typically caused by weak pelvic muscles.
For a detailed explanation of the underlying science, see [What Really Causes Bedwetting? A Parent’s Guide to the Science](https://www.sleepsecurenights.com/what-really-causes-bedwetting-a-parent-s-guide-to-the-science/).
In 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 at night may be insufficient, or the arousal threshold may be high. None of these are addressed directly by pelvic floor exercises.
## What Does the Evidence Show?
Research specifically on pelvic floor exercises for nocturnal enuresis in girls is limited and largely inconclusive when exercises are used alone. Most studies examine pelvic floor training as part of a broader bladder rehabilitation program—including biofeedback, urgency suppression techniques, and fluid management.
### Stronger Evidence: Daytime Wetting and Overactive Bladder
The evidence is clearer for daytime symptoms. Pelvic floor training, especially with biofeedback, has reasonable support for overactive bladder (OAB) and daytime urge incontinence in children. A 2014 systematic review in the *Journal of Urology* found biofeedback-assisted pelvic floor training beneficial for dysfunctional voiding, mainly during the day.
If a girl experiences both daytime wetting and bedwetting, addressing daytime symptoms first—or alongside—is logical. See [My Child Is Wetting During the Day: How Daytime and Nighttime Wetting Relate](https://www.sleepsecurenights.com/my-child-is-wetting-during-the-day-how-daytime-and-nighttime-wetting-relate/).
### Limited Evidence for Isolated Nocturnal Enuresis
For bedwetting without daytime symptoms, pelvic floor exercises alone have not shown significant benefit. NICE guidelines (CG111) do not list pelvic floor training as a first-line treatment. Their recommended hierarchy involves enuresis alarms and desmopressin, sometimes combined.
This does not mean exercises are harmful or pointless; rather, they are unlikely to be sufficient if the underlying cause is hormonal or arousal-related rather than muscular.
## When Might Pelvic Floor Exercises Be Useful?
Pelvic floor training may help in specific situations:
– **Daytime urgency alongside nighttime wetting** — improving daytime bladder control may reduce overall bladder instability.
– **Post-void dribbling or incomplete emptying** — some girls have poor voiding coordination, which pelvic floor awareness can help improve.
– **Dysfunctional voiding** — where a child contracts rather than relaxes the pelvic floor during urination; diagnosis should be by a specialist.
– **Part of a structured bladder training program** — combining scheduled toileting, urgency suppression, and pelvic floor exercises has more evidence.
If any of these apply, a referral to a paediatric continence nurse or physiotherapist with pelvic health expertise is advisable. Your GP can facilitate this.
## How Pelvic Floor Exercises Are Taught to Children
Adult Kegel instructions do not translate well to children. Younger girls benefit from age-appropriate explanations—such as visualising “squeezing as if stopping a wee” or “lifting a lift inside your tummy”—and guided practice rather than written instructions.
Biofeedback equipment used in clinics provides real-time feedback, improving accuracy. Many children who think they are contracting the right muscles are actually tensing the wrong ones.
Home practice typically involves 10–15 contractions, two to three times daily, with quick flicks and sustained holds. Consistency is more important than duration. Results, where they occur, usually take six to twelve weeks.
## What to Expect
If a girl is doing pelvic floor exercises for bedwetting without daytime symptoms, the realistic expectation is that exercises alone are unlikely to resolve the issue. They are harmless and can increase awareness of the pelvic floor, but should not replace evidence-based treatments like alarms or medical review.
If standard approaches have failed, see [Next Steps After Trying Alarms and Medication](https://www.sleepsecurenights.com/we-have-tried-the-alarm-desmopressin-lifting-and-nothing-has-worked-next-steps/). For deciding whether to involve a clinician, [When Is Bedwetting a Problem?](https://www.sleepsecurenights.com/when-is-bedwetting-a-problem-signs-it-s-time-to-talk-to-a-doctor/) offers guidance.
## Anatomy and Gender Considerations
Girls have a shorter urethra than boys, and differences in voiding anatomy influence continence. This partly explains why research on pelvic floor training in children often focuses on females. However, bedwetting mechanisms are similar across sexes; pelvic floor training’s relevance remains consistent.
## Summary
Pelvic floor exercises for girls with bedwetting are not strongly supported by evidence when used alone for nighttime wetting. They are more supported for daytime overactive bladder symptoms and may be part of a broader treatment plan if there are mixed symptoms or specific voiding issues.
Discuss with a GP or continence nurse, especially if daytime urgency or unusual voiding patterns are present. They are not a substitute for proper clinical assessment. Managing bedwetting often involves addressing multiple factors simultaneously.
