The Bladder does not shrink as you get Older!
The idea that your bladder shrinks as you get older may be nothing more than an old wives’ tale. The feeling may, however, signal a treatable underlying condition. In a “Life history of the female bladder: normal aging versus detrusor overactivity”, researchers compared data on bladder capacity and stability, urethral closure pressure, voiding flow rate and detrusor contraction strength from 95 females between the ages of 22 and 9.
The researchers found that while bladder and urethral function deteriorate throughout adult life, bladder capacity rarely changes. Women with normally aging bladder had weaker bladder sensation; while women who experienced increased bladder sensation actually had an underlying condition called detrusor overactivity (DO), often referred to as overactive bladder. In DO/OAB, the muscle that controls involuntarily, creating a strong, sometimes uncontrollable urge to empty the bladder.
