The adrenal glands sit on top of the kidneys. Cortisol, the stress hormone, is what might come to mind when you hear the words “adrenal glands,” and while that’s important, this organ is so much more. Different parts of the adrenal glands secrete different hormones that affect all aspects of life. Aldosterone, cortisol, estrogen, progesterone, DHEA, testosterone, epinephrine and norepinephrine are all secreted by the adrenal glands. Impaired function of any of these hormones has significant effect on your overall health.
