Type

Etiologies

Normal Sodium Regulation

Osmoreceptors in hypothalamus sense serum sodium
Elevated serum sodium stimulates ADH (vasopressin) release from pituitary

ADH

Stimulates water reabsorption in kidney to lower serum sodium concentration, which turns off osmoreceptors in brain

Thirst reflex stimulated to cause water intake to lower serum sodium to normal
