Overactivity of the bladder is a common condition that crops up in old age but may appear at any age. Overactive bladder is a condition in which bladder muscles contract uncontrollably and cause frequent urination. This creates an urgent need to urinate and an inability to control urination in adults.
Both men and women can suffer from this condition, but women tend to suffer more often than men. The symptoms of this phenomenon are frequent urination both day and night and a sudden urge to urinate that is difficult to control.
In children three years of age and older, the condition known as neurogenic detrusor overactivity produces a loss of bladder control caused by brain, spinal cord, or nerve problems or multiple sclerosis.
