This condition is called Urge Incontinence or Overactive Bladder. This condition is called Prolapse. The need to urinate varies based on what and how much one drinks. In general, the bladder should empty every 3 to 6 hours or 4 to 6 times in 24 hours. The average bladder capacity is 10 to 20 ounces, though this decreases a bit with aging.
Most adults feel no signal to urinate until the bladder is about half full or more.
After that first signal, the sensation subsides temporarily. As the bladder gets fuller, the signal returns and gets stronger and more frequent, but still subsides if urination needs to be delayed. It is not normal to have to rush to the toilet. Even after the first warning, people with normal bladder function can usually postpone emptying the bladder until the appropriate time and place. The first warning of the need to go can occur 1 to 2 hours before the bladder is actually full.
