Healthy bladders are often compromised by extended sitting and poor bathroom facilities (in both quality and quantity)—both common aspects in our nation’s schools and workplaces. These conditions often account for the retraining of the bladder to store a larger volume of urine than is medically recommended. This can cause a sluggish bladder, which results in the urge to empty the bladder again in a relatively short amount of time.
The bladder is simply a reservoir for urine and not designed to store copious amounts of urine. The brain signals the urge response when a pre-set amount (which varies per individual) is stored. A good rule of thumb is to comfortably wait to empty the bladder every couple of hours. Many individuals, especially women, have a tendency to ignore this urge and will wait to urinate when their bladder is two or three times larger than the recommended volume. Regular flushing of the bladder serves to discourage bacterial growth, while maintaining proper bladder size and elasticity. An overstretched bladder is not going to recoil as effectively (think of an overused rubber band) and eventually will become sluggish.
