In the context of urinary issues, what does oliguria refer to?

Oliguria is a medical term that is specifically used to describe a condition characterized by a reduced volume of urine output. Typically, it is defined as urine output of less than 400 milliliters per day in adults. This condition can indicate potential underlying health issues, such as dehydration, kidney dysfunction, or other medical conditions that may impair normal kidney function. Understanding oliguria is crucial in clinical settings as it may require prompt medical evaluation and intervention to address the underlying causes and prevent complications.
