How does Diabetes Insipidus affect urine output?

Diabetes Insipidus is a condition characterized by an impairment in the body's ability to concentrate urine due to a deficiency of the hormone vasopressin (also known as antidiuretic hormone or ADH) or a lack of response to it. When vasopressin is inadequate or absent, the kidneys are unable to reabsorb water effectively. This results in the excretion of large volumes of dilute urine.

Individuals with Diabetes Insipidus typically experience polyuria, which refers to excessive urination. The inability to concentrate urine leads to an increase in urine volume. Therefore, the correct answer highlights that the condition causes an increase in urine output, leading to potentially severe dehydration if fluids are not adequately replaced.

In the context of other potential answers, while electrolyte concentration and urine volume changes are associated with various renal and endocrine functions, they do not capture the primary effect of Diabetes Insipidus on urine output as accurately as the increase in urine volume does.
