Final answer:
A daily urine output of > 2000 mL/day is called polyuria, and it is commonly associated with conditions such as Diabetes Mellitus and Diabetes Insipidus.
Step-by-step explanation:
The daily urine output of > 2000 mL/day is called polyuria. This condition is commonly seen with Diabetes Mellitus, which occurs when blood glucose levels exceed the capacity of the kidney's sodium-glucose transporters. The excess glucose in urine draws water with it, leading to increased urine output. Polyuria can also be caused by Diabetes Insipidus, where there is a deficiency of antidiuretic hormone (ADH) or the kidneys' response to ADH, resulting in less water being reabsorbed and more dilute urine being produced.
