What is the production of large amounts of urine by the kidney called?

The term that refers to the production of large amounts of urine by the kidney is diuresis. This condition indicates an increased volume of urine output, which can occur for various reasons, including excessive fluid intake, certain medications, or underlying health conditions such as diabetes mellitus. Diuresis is a physiological response that allows the body to regulate fluid balance and electrolyte levels effectively.

In contrast, oliguria denotes a condition where urine output is abnormally low, which is the opposite of diuresis. Uremia refers to a build-up of waste products in the blood due to kidney failure, rather than the quantity of urine produced. Hematuria indicates the presence of blood in urine, which does not pertain to the volume of urine produced. Understanding these definitions helps clarify that diuresis specifically relates to the increased production of urine.
