Scientists from University of Pittsburgh had said in a new study that there's adequate proof that bladder does not shrink in size with age, in spite of the elderly frequenting the bathroom more.
Researchers had compiled data on bladder capacity and stability, urethral closure pressure, voiding flow rate and detrusor contraction strength from 95 females of ages 22 to 90. The results were that what happens is that functionality of the bladder and the urethra decreases but the size of the bladder does not change.
Women with age experience less bladder sensations. For women who experience increased bladder sensations suffers from a condition called overactive bladder or detrusor over activity (DO). This is the condition where the detrusor muscle related with emptying of the bladder contracts and provides the sensation of needing to urinate more frequently.
The condition of overactive bladder affects a lot of people although only a few seek medical advice. The characteristics of such a condition are frequent urination, urgent need to urinate, and for some, urine incontinence or inability to control urination resulting in urine leakage.
The scientists of the research published their results in the annual meeting of the American Urological Association.
