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.
Most bladders are full with about 20 ounces of pee in them, this is the average size of a bladder. If you're into holding in your pee it may take more in order to fill it up. Here's a technique that will fill your bladder fast no matter what size it is.<br /><br />Drink 10 ounces of water every 15 minutes. This will make your kidneys produce more urine over time, without using drugs. Do this for 2 hours or so while going to the bathroom whenever you feel a full bladder.
