Q37 (IAS/2005) Science & Technology › Biotechnology & Health › Human genetics and disorders Answer Verified

Assertion (A) : The person with diabetes insipidus feels thirsty. Reason (R) : A person with diabetes insipidus suffers from excess secretion of vasopressin.

Result
Your answer: —  Â·  Correct: C
Explanation

The chief clinical features of diabetes insipidus (DI) include passage of large volumes of dilute urine with compensatory thirst and excessive fluid intake (polydipsia), so the assertion that a person with DI feels thirsty is correct [3]. However, DI is caused by either inadequate production/secretion of vasopressin (central/AVP deficiency) or by renal resistance to vasopressin (nephrogenic/AVP resistance), not by excess vasopressin secretion. Thus the reason given (excess vasopressin) is incorrect; the disorder reflects deficiency or resistance of vasopressin action rather than hormone excess [3]. Therefore A is true and R is false.
