While you may have heard about Overactive Bladder (OAB) due to lots of media attention, many do not know about Underactive Bladder (UAB). UAB is a syndrome that includes the urinary symptoms of hesitancy, straining and incomplete bladder emptying in the absence of any blockage of the bladder or the urethra. The current definition of underactive bladder (UAB) states, “UAB is characterized by a slow urinary stream, hesitancy, and straining to void with or without a feeling of incomplete bladder emptying, sometimes with storage symptoms.”
What Is Underactive Bladder?
UAB is a serious, ongoing, and difficult disease and it has serious consequences if not treated. Your healthcare professional may refer to underactive bladder as detrusor underactivity, hypotonic bladder, flaccid bladder, lazy bladder, and detrusor hypoactivity. A diagnosis of UAB is usually confirmed with pressure flow urodynamic tests and patient history. How many people have UAB is not known, and studies are needed to determine its prevalence.
