Plasma arginine vasopressin level in hypothyroid women in relation to dietary sodium supply.

Introduction: A disturbed regulation mechanism of arginine vasopressin secretion in response to plasma osmolality and volaemia changes occurs in hypothyroidism. The aim of this study was to determine plasma arginine vasopressin concentration in hypothyroid women under conditions of a low sodium diet and in an upright position.

Material And Methods: Twenty-six women with primary hypothyroidism and 24 healthy women (control group) were investigated.
