Your kidneys make urine, which is transported to your bladder along tubes called ureters.

The urine then sits in your bladder. Your bladder can hold about 500ml of urine, but you feel the need to go when it’s holding around 300ml.

To urinate, your urethral sphincter (the muscle controlling the bladder outlet) and pelvic floor muscles relax, and your bladder contracts (squeezes) so that it empties.

Most people empty their bladder four to eight times a day.

Tips for a healthy bladder

Good habits can help you avoid bladder control problems.

For a healthy bladder:

• urinate four to eight times a day, but no more than twice each night
• try not to go ‘in case’ – wait until your bladder is full (although going before bed is sensible)
• when you go, completely empty your bladder
• drink plenty of water – six to eight cups a day for most people
• include fibre in your diet so you don’t strain when opening your bowels
• don’t have too much caffeine, as it can irritate your bladder
• keep your pelvic floor muscles strong

Women should sit on the toilet seat, rather than hover over it.

Bladder problems symptoms

Speak to your doctor if you’re having problems with your bladder.

Symptoms include:

• wetting yourself (even a little) when you cough, sneeze, laugh or when active
• feeling an urgent need to urinate, or not getting there in time
• passing small amounts of urine more than eight times daily
• unexpected changes in your bladder habits

Loss of bladder control

If you can’t always control your bladder function, you may have urinary incontinence. Urinary incontinence is any involuntary (accidental) loss of urine from your bladder. It ranges from small ‘leaks’, to complete loss of control.

If you think you have incontinence, contact your doctor or the National Continence Helpline on 1800 33 00 66.
