AI is a medical condition in which the adrenal glands cannot produce glucocorticoid hormone Cortisol. Cortisol is needed for the body to maintain normal energy supply, fluid and electrolyte balance, blood pressure, blood sugar and the body’s reaction to physical stress such as illness or injury.. , MD.
