Become Dizzy When Standing Up Suddenly

Becoming dizzy when standing up is a classic sign of low adrenal function. The adrenal glands are responsible for keeping the blood pressure in the normal range for the few seconds of compression after moving from a recumbent to a standing position. Weakness in the adrenal gland can cause dizziness when standing, known as orthostatic hypotension. A drop of 10 or more points in the systolic blood pressure reading when taken recumbent and standing is a sign of adrenal insufficiency.
