Giggle incontinence is one of the strangest patterns I see in my clinic. A child, usually a girl between six and ten, is fully dry day and night, with no history of bladder problems. And then she laughs hard, and her bladder empties completely. Not a few drops. The whole bladder, and the flow does not stop until the bladder is empty, even after the laughter has passed.
What giggle incontinence actually is
Giggle incontinence (sometimes called enuresis risoria) is a specific, narrow phenomenon. It is triggered only by laughter, almost always belly laughter, and it happens during waking hours. The mechanism appears to involve an involuntary reflex in which the bladder muscle contracts at full force while the sphincter relaxes. The result is total emptying, completely outside the child's control.
It is far more common in girls than in boys. Most children who experience it have completely normal daytime control in every other situation and are dry at night.
Is it connected to bedwetting?
No. This is the question I am asked most often, and the answer is clear. Giggle incontinence and bedwetting (nocturnal enuresis) are two different problems with two different mechanisms. One is a daytime laughter-triggered reflex; the other is a nighttime failure to recognise a full bladder during deep sleep. A child can have either, both, or neither. Treating one does not automatically resolve the other.
What helps
The treatment for giggle incontinence focuses on teaching the child to consciously control and isolate the pelvic floor muscles. Targeted exercises help the child learn to contract the sphincter independently while the bladder is under pressure. With practice, most children gain enough voluntary control to interrupt the reflex before it empties the bladder.
It takes time. The child has to build awareness of muscles she has never had to think about, and laughter is not exactly something you can practise on demand. But the prognosis is generally good, and most cases improve significantly with consistent work.
What about our bedwetting programme?
Our treatment is built for nocturnal enuresis, not for giggle incontinence. That said, the bladder-strengthening exercises that are part of the daytime training in our programme can sometimes improve giggle incontinence as a side benefit. It is not guaranteed, but I have seen it happen often enough to mention it. Read more about the science of bedwetting.
