Causes of Urinary Incontinence
by Ricker Polsdorfer, MD
There are several types of urinary incontinence. The causes vary depending on the type.
Temporary incontinence can be caused by:
Many medications can cause urinary problems, including blood pressure pills, sleeping pills, indigestion remedies, and antidepressants. Talk with your doctor if you are suffering from incontinence and are taking any type of medication.
More permanent incontinence may be classified as one of the following 4 types. Some people have a mixture of these types. In some cases, incontinence may have several different causes. Sometimes the cause is unclear.
Stress incontinence results when certain activities increase pressure on the bladder. Leaking can be triggered by laughing, sneezing, lifting heavy objects, or exercise. This is the most common type of incontinence and may be caused by:
Urge incontinence is loss of bladder control following a strong urge to urinate. You are unable to hold urine long enough to make it to the bathroom. This is also known as overactive bladder. It may be caused by:
Overflow incontinence occurs when the bladder is full. The increased pressure generated by an over-full bladder exceeds the strength of the valve holding urine in. It may be caused by:
When nerve controls to your bladder are absent, as in spinal cord injury, the bladder will empty when it reaches a certain volume. This is called a neurogenic bladder. If you have this condition, you will learn how to drain urine periodically or permanently with a tube called a catheter inserted directly into your bladder.
Your bladder control may be perfectly normal, but any mental or physical condition that slows you down or confines you may result in loss of urine. This is called functional incontinence.
Other Causes of Incontinence TOP
Occasionally an abnormal channel called a fistula opens between the bladder and the outside world. It can be from a birth defect, an injury, or a complication of surgery. Fistulas cause continuous, uncontrolled urine dribbling and can be surgically repaired.
