Bladder Health

Signs of a healthy bladder

A healthy bladder:

  • empties 4-6 times each day
  • can hold up to 400-600ml of urine (the sensation of needing to empty occurs at 200-300 ml)
  • may wake you up once at night to pass urine and twice if you are older (i.e. over 65 years of age)
  • tells you when it is full but gives you enough time to find a toilet
  • empties completely each time you pass urine
  • does not leak urine.

How the bladder works

The bladder is a storage organ that sits in your pelvis. Urine (wee) is made by your kidneys and is stored in the bladder until you are ready to empty it.

When you go to the toilet your bladder outlet muscles (urethral sphincter and pelvic floor) relax and your bladder contracts (squeezes) emptying the urine. Your brain controls your bladder by sending messages through the nerves in your spinal cord to tell it when to hold on and when to empty.

Bladder control problems

In Australia one in three women, one in ten men and one in five children have a bladder control problem. People who experience accidental or involuntary loss of urine from the bladder may be suffering from urinary incontinence.
