What does anuria indicate?

Anuria is a medical term that specifically indicates a complete absence of urine production. This condition can arise from various underlying health issues such as acute kidney failure, severe dehydration, or blockages in the urinary tract.

Understanding the significance of anuria is crucial, as it can be a serious health concern indicating that the kidneys are not functioning properly. While the other choices describe different urinary conditions, they do not relate to the absence of urine production as anuria does. Frequent urination, increased daily urine volume, and slow and painful urination represent distinct urinary symptoms or disorders, making them unrelated to the definition of anuria.
