Question

Hyposecretion of which hormones cause diabetes insipidus and diabetes mellitus respectively?

• A. ADH, Glucagon
• B. Glucagon, ADH
• C. ADH, Insulin
• D. Insulin, ADH

Answer 1

The correct option is C ADH, Insulin

Hyposecretion of ADH

• Water absorption is reduced and the amount of water in urine is increased.
• This condition of diluted urine (Diuresis), without sugar or glucose, is called diabetes insipidus.
• (It is different from diabetes mellitus in which sugar/glucose passes with urine).

Hyposecretion of Insulin

• It causes hyperglycaemia as the amount of glucose is increased in blood.
• As the permeability of the plasma membrane is decreased the cells can not utilize this glucose for energy production. The glucose, therefore, is excreted with urine (glycosuria).
