What causes urge incontinence?

ANSWER

Urge incontinence is caused by abnormal bladder contractions. Normally, strong muscles called sphincters control the flow of urine from the bladder. With urge incontinence, the muscles of an "overactive" bladder contract with enough force to override the sphincter muscles of the urethra, which is the tube that takes urine out of the body.
