What Does Decreased Urine Output Mean?

Decreased urine output, also known as oliguria, means that the body is producing less urine than normal. This can happen for various reasons, and understanding the cause is important.

1. Normal Renal Function: Sometimes, even with normal kidney function, the body may produce less urine. This can occur during surgery or when the body is trying to conserve fluids, as noted by Zaloga and Hughes.

2. Acute Kidney Injury: Decreased urine output can also be a sign of acute kidney injury, where the kidneys suddenly stop working as well as they should. This is a more serious condition that requires medical attention, as discussed by Chenitz and Lane-Fall.

3. Renal Replacement Therapy: In some cases, especially during treatments like dialysis, decreased urine output is monitored closely. Zhang and colleagues highlight the importance of keeping track of urine output during such therapies to ensure proper treatment.

Understanding the reason behind decreased urine output is crucial, as it can range from a normal body response to a sign of a more serious condition. If someone is experiencing this, they should consult a healthcare professional for further evaluation.
