Detailed explanation-1: -The normal range for 24-hour urine volume is 800 to 2, 000 milliliters per day (with a normal fluid intake of about 2 liters per day).
Detailed explanation-2: -Median daily water intake was 1.4 L (IQR 0.67–1.94). Median 24-hour urine volume was 2.01 L (IQR 1.20–2.73). A 1 L increase in daily water intake was associated with a 710 mL increase in 24-hour urine output (95% CI 0.55–0.87).
Detailed explanation-3: -Urine volume is considered excessive if it equals more than 2.5 liters per day. A “normal” urine volume depends on your age and gender. However, less than 2 liters per day is usually considered normal. Excreting excessive volumes of urine is a common condition but should not last more than several days.
Detailed explanation-4: -How Much? Under the usual conditions of life, 3 – 4 liters of fluids a day will provide 2.5 to 3 liters of urine volume, and this is enough. The average healthy adult bladder holds about 1/2 liter, so this means 7 – 9 bathroom trips in 24 hours.
Detailed explanation-5: -Most adults make at least 500 mL of urine in 24 hours (a little over 2 cups).
