Overflow incontinence occurs as the result the bladder being stretched beyond its normal holding capacity, resulting in the leakage of urine that can be almost continuous. There are two main causes of this type of incontinence. It sometimes occurs as the result of some type of blockage in the urinary tract, or may be caused by weak contraction of the bladder. In either case, the result is urine that dribbles out due to the pressure of an overly full bladder.

In men, an enlarged prostate may partially occlude the bladder neck, causing the bladder to become overly distended. Stricture (narrowing) of the bladder neck following prostate surgery can also cause overflow incontinence. Stones of the urinary tract in both men and women can also contribute to overflow incontinence. In addition, any health condition that affects the nerves supplying the bladder, such as Multiple Sclerosis or diabetes, can cause this problem.

Constipation can also cause overflow incontinence when an overly full rectum applies pressure to the urethra or bladder neck. Increasing water intake and modifying your diet to avoid constipation can help prevent overflow incontinence. Medications which cause incontinence are sometimes at the root of the problem, leading to a “paralysis” of the bladder.

If you suffer from overflow incontinence, it is important to seek the guidance of your physician, as some of the causes of this condition may be reversible. In the meantime, choosing absorbent incontinence pads or pants will help you to feel comfortable and secure.
