Oliguria is defined as what?

Oliguria is defined as a decrease in daily urine volume. It typically indicates that the body is producing less urine than what is considered normal, which can be a sign of dehydration, kidney dysfunction, or other medical conditions that affect the body's ability to produce urine.

In veterinary medicine, understanding oliguria is crucial for diagnosing and managing conditions that lead to renal insufficiency or other issues affecting urinary output. Monitoring urine production can provide valuable insights into an animal's health status, and recognizing a decrease in urine volume allows practitioners to take appropriate action to address underlying causes.

The other definitions in the options do not accurately represent oliguria. Frequent urination suggests an increased frequency of urination, while no urine production is referred to as anuria. Increased daily urine volume is described as polyuria. These terms highlight different conditions of urine production and are not interchangeable with oliguria.
