what hormone deficiency cause dehydration
Higher concentrations of anti-diuretic hormone cause blood vessels to constrict (become narrower) and this increases blood pressure. A deficiency of body fluid (dehydration) can only be finally restored by increasing water intake.nti-diuretic hormone acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney. Alternative names for anti-diuretic hormone Vasopressin; arginine vasopressin; AVP; ADH.
