What is considered a normal urine output for adults over 24 hours?

The normal urine output for adults over a 24-hour period typically ranges from 800 to 2000 milliliters. This range reflects the body's ability to filter blood through the kidneys, where excess fluid and waste are excreted as urine. A urine output within this range indicates that the kidneys are functioning properly and effectively regulating fluid balance in the body.

Factors such as fluid intake, temperature, physical activity, and overall health can influence individual urine output. However, outputs below 800 milliliters can indicate dehydration or kidney dysfunction, while outputs exceeding 2000 milliliters might suggest excessive fluid intake or conditions such as diabetes insipidus.

A range of 100 to 500 milliliters would generally be considered low and could raise concerns about possible dehydration or renal issues. Outputs of 500 to 800 milliliters are also on the lower side of normal and might warrant further investigation if persistent. Similarly, values exceeding 2000 to 3000 milliliters may indicate excessive fluid intake or other underlying medical conditions that require attention.
