Intake-Output Ratio



Hi expert, what is the normal intake-output ratio? If I drink 2 litres of water, what is my urine volume which is normal for 2-l intake of water?


Thanks for your question.  Normal urine output in a 24-hr period is about 1 1/2 liters of water.  If you drink 2 liters, you will likely urinate out about 1 1/2-2 liters in that time frame.
