Author: Jared Scott M.D.

Educational Pearls:

  • Adrenal glands sit on top of kidneys, and are approximately the size of a walnut.
  • Each of the different layers of the adrenal glands make hormones and those hormones become more desirable with each layer – salt hormones→ sugar hormones→ sex hormones.
  • Top layer: the zona glomerulosa makes aldosterone, which moderates sodium, potassium, and BP.
  • Zona fasciculata makes cortisol, which helps with sugar and BP management.
  • Zona reticularis makes progesterones, androgens, and estrogen precursors – or the “sex” hormones.
  • Deepest layer: adrenal medulla produces epinephrine and norepinephrine.
  • Critically ill patients without adrenal glands can have major complications and need to have their missing hormones replaced.
  • Adrenal function can also be suppressed from long-term daily steroid use.
