Normal Urine Output: How Much is Healthy?

The normal urine output for an adult is between 1 and 2 liters per day. This means that you should urinate about every 2 to 4 hours. However, the amount of urine you produce can vary depending on a number of factors, including your fluid intake, activity level, and medications you are taking. If you are concerned about your urine output, talk to your doctor.
