What Is It?
Urinary incontinence is a loss of control over urination. Urine leaks before you are able to get to a toilet.
There are many types of urinary incontinence.
One type is stress incontinence. Your pelvic muscles are located beneath your bladder. Stress incontinence occurs when your pelvic muscles aren't strong enough. They cannot withstand a "stress" or pressure pushing on the bladder.
When your pelvic muscles give way, they release their squeeze around the bottom of your bladder. As a result, urine can drain out.
