Giggle incontinence, giggle enuresis or ''enuresis risoria'' is the involuntary release of
urine Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excretion, excreted from the body through the urethra. Cel ...

puberty Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy. ...

A survey of 99 student nurses indicated that about 25% had experienced such a wetting event during their lifetime, and about 10% were still susceptible in their late teens.

Cause

contracts to squeeze urine from the bladder. One study, of 109 children diagnosed with giggle incontinence at Schneider Children's Hospital in New York, concluded that the cause of giggle incontinence is involuntary contraction of the detrusor muscle induced by laughter. Because the complaint is difficult to reproduce under controlled conditions, its triggering mechanism is not clearly understood, but may be related to

often triggered by strong emotions.


Social consequences

Episodes of giggle incontinence are embarrassing and socially incapacitating, diminishing the quality of life. Those having the condition learn to adapt by avoiding activities that may bring on laughter (such as being tickled, watching a funny movie or TV program, or reading/listening to funny stories or jokes). Other approaches include limiting fluid intake, trying to remain seated, and concealing leakage by wearing absorbent pads and dark clothing.

(Ritalin) has been reported, but this treatment option is not acceptable to all patient families. Dr. Lane Robson, of The Children's Clinic in Calgary, Alberta, says "If a child is having a wetting episode once a month, medicating them daily is probably not a good treatment. If it's a daily issue, you may have to make that decision."
