People who suffer from an overactive bladder have a detrusor muscle (a muscle in the bladder) that contracts:
-Suddenly (without warning).
-Erratically (with or without a full bladder).
-Involuntarily (difficult to control).
-More often that it should (Urination with a half-full or less than half-full bladder).
The detrusor muscle (bladder) follows signals that are not coordinated with the bladder/nerves/brain, provoking immediate contraction upon receiving them, including when the bladder isn’t completely full, thereby voiding the patient’s voluntary control.
When your bladder contracts, you feel an intense urge to urinate and immediately need to go to the bathroom. If you’re not able to go to the bathroom, the bladder empties itself. If you’ve not made it to the bathroom on time, your clothing may get wet due to loss of urine.
Why does this change occur?
Why are the signals between the brain and the bladder interrupted?
Overactive bladder/urinary incontinence is a syndrome and is therefore considered a set of symptoms. There are many theories as to its origin. Despite recognising that there’s a failure in the nerve connections between the bladder and the brain, the exact mechanisms have not yet been discovered.
Treatment for this syndrome attempts to restore the mechanisms that could have failed, including the nerve function of the bladder, which is one of the fundamental pillars of the treatment.
