What is the normal range for urine volume per day?

The normal range for urine volume per day is typically considered to be between 800 to 2000 ml. This range is determined by several factors including hydration status, diet, and individual kidney function. Generally, most healthy adults produce about 1 to 2 liters of urine daily, which corresponds well to this range.

Volume below 800 ml may indicate low fluid intake or dehydration, while volumes exceeding 2000 ml could suggest conditions such as diabetes insipidus or excessive fluid intake. Therefore, the choice reflecting 800 to 2000 ml encapsulates the commonly accepted standard for normal daily urine output, indicating healthy kidney function and proper hydration levels. This well-established range is supported by clinical guidelines and provides a useful framework for monitoring kidney health and fluid balance.
