What condition is characterized by inadequate secretion of ADH, leading to increased urine output?

The condition characterized by inadequate secretion of antidiuretic hormone (ADH), resulting in increased urine output, is indeed known as diabetes insipidus. In this disorder, the kidneys are unable to concentrate urine due to insufficient levels of ADH, also known as vasopressin. This leads to excessive thirst and the production of large volumes of dilute urine.

Understanding the role of ADH is crucial; it is responsible for regulating water balance in the body by promoting water reabsorption in the kidneys. When there is a deficiency of this hormone, the kidneys do not reabsorb water effectively, leading to polyuria (increased urine production) and an increased risk of dehydration.

In contrast, diabetes mellitus is related to issues with insulin and glucose metabolism rather than ADH; hypothyroidism involves deficiencies in thyroid hormone that affect metabolism but not the action of ADH; and cirrhosis is a liver condition that impacts various bodily functions but does not specifically cause the increased urine output linked to ADH deficiency.
