Question

Diabetes insipidus is a syndrome in which an underproduction of ________ exists.
A) insulin
B) parathyroid hormone
C) mineralocorticoids
D) thymosin
E) antidiuretic hormone

Accepted Answer

Diabetes insipidus is a disorder caused by a lack of antidiuretic hormone (ADH), also known as vasopressin. ADH normally helps to regulate the body's water balance by reducing the amount of urine produced by the kidneys. Without sufficient ADH, excessive amounts of dilute urine are produced, leading to dehydration and electrolyte imbalances. The other options listed (insulin, parathyroid hormone, mineralocorticoids, and thymosin) are not involved in the regulation of water balance in the body.
