Loss of urine when you exert pressure on your bladder by coughing, sneezing, laughing, exercising or lifting something heavy. Stress urinary incontinence occurs when the sphincter muscle at the bladder is weakened. The problem is especially noticeable when you let your bladder get too full. Physical changes resulting from pregnancy, childbirth and menopause can cause stress incontinence.
This is a sudden, intense urge to urinate, followed by an involuntary loss of urine. Your bladder muscle contracts and may give you a warning of only a few seconds to a minute to reach a restroom. With urge incontinence, you may also need to urinate often. The need to urinate may even wake you up several times a night. The bladder becomes "overactive", or it contracts even when your bladder is not full. Urge incontinence is often called an overactive bladder.
If you frequently or constantly dribble urine, you may have overflow incontinence. This is an inability to empty your bladder, which leads to overflow. With overflow incontinence, sometimes you may feel as if you never completely empty your bladder. When you try to urinate, you may produce only a weak stream of urine. This type of incontinence is common in people with a damaged bladder or blocked urethra. Nerve damage from diabetes also can lead to overflow incontinence.
If you experience symptoms of more than one type of urinary incontinence, such as stress incontinence and urge incontinence, you have mixed incontinence. Usually one type is more bothersome than the other is.
