What is stress urinary incontinence?
Stress urinary incontinence is a very common problem and is thought to affect millions of people.
Stress urinary incontinence is usually the result of the weakening or damaging of the muscles that are used to prevent urination, such as the pelvic floor muscles and the urethral sphincter. This then causes urine to leak when your bladder is under pressure, for example when you cough or laugh.
The amount of urine passed is usually small, but stress urinary incontinence can also cause you to pass larger amounts, particularly if your bladder is very full.
