What does the term oliguria refer to?

Oliguria refers to a medical condition characterized by decreased urine output, typically defined as urine production that is less than 400 milliliters per day in adults. This condition can indicate underlying health issues, such as dehydration, kidney problems, or urinary obstructions. Understanding oliguria is essential for healthcare professionals, as it can be a critical sign that requires further investigation and management to address any potential health concerns. The distinction between oliguria and other terms related to urine output is crucial in clinical practice, where monitoring kidney function and hydration status is vital for patient care.
