Women are seen to have twice the amount of incidence of urinary incontinence than men. Urinary incontinence is more prevalent in aged women but it is not age dependent as it is a medical problem.
At the time of urination the urinary bladder muscles contract and urine is thrown out of the bladder to the urethra. At this time the muscles of the urethra relax and the urine is thrown out of the body. If the bladder muscles contract suddenly or the urethra muscles are weak and unable to hold the urine then the urine may come out with low pressure.
The problem of urinary incontinence is very common in women and it is treatable at all ages.
