A person passes much urine and drinks much water but his blood glucose level is normal. This condition may be the result of

  • A
    A reduction in insulin secretion from pancreas
  • Correct answer
    B
    A reduction in vasopressin secretion from posterior pituitary
  • C
    A fall in the glucose concentration in urine
  • D
    An increase in secretion of glucagon

Solution

As the basic function of vasopressin (a hormone secreted from neurohypophysis) is to conserve body's water. Its failure or hyposecretion leads to a reduction in renal absorption of water and a consequent elimination of a large volume of dilute (hypotonic) urine, i.e., diabetes insipidus.

Hence, the correct answer is option: 'B'.
