Low Blood Pressure?
Could Be Adrenal Gland Dysfunction
The adrenal glands produce a hormone called Aldosterone which maintains blood pressure. It does this by acting on the kidneys to retain salt thus retaining water which increases blood volume and subsequently blood pressure.
If the adrenal glands are hypo-functional (under producing) then resting blood pressure may be low (causing dizzy or light-headed feeling). Low Aldosterone means salt is getting lost in the urine and not retained. The body may compensate with salt cravings (salty foods) and/or increased thirst.
