The bladder stores urine until you are ready to empty it. It swells into a round shape when it is full and gets smaller as it empties. A healthy bladder can hold up to 16 ounces (2 cups) of urine comfortably. How frequently it fills depends on how much excess water your body is trying to get rid of.
How often you pass urine depends on how much urine is produced as well as how much urine the bladder will hold. If you drink 1.5 litres a day and your bladder normally holds 400 millilitres (ml), then you will empty your bladder approximately four times that day. A bladder that holds only 100 ml results in passing urine 15 times. If you drink twice as much, you will need to empty your bladder twice as frequently. Normal frequency of voiding is up to seven times a day or not more than every two hours. In young women, the bladder normally holds 400 to 600 ml and is usually emptied when holding 250 to 400 ml. As people age, their bladder capacity tends to decrease, leading to increased frequency of micturition (voiding), especially at night.
