Adrenal Crisis

(Acute Adrenocortical Insufficiency)


Adrenal crisis is a life-threatening condition. It is caused by a deficiency of a hormone called cortisol. Cortisol helps to keep the body in balance with influence over blood sugar levels, immune system, blood pressure, and more. Cortisol is made in the adrenal glands which sit just above the kidney. However, the pituitary gland, which sits just below the brain, regulates how much cotrisol should be made.
