Cortisol is a hormone produced by the adrenal glands, states Healthline. Cortisol helps the body to respond effectively to stress. Cortisol also plays a role in bone health, the immune response and food metabolism.
Low levels of cortisol cause weakness, fatigue and low blood pressure, notes Healthline. Addisonian crisis is a condition in which the cortisol level falls rapidly. Addisonian crisis is a life-threatening condition that requires emergency medical attention. The patient with Addisonian crisis can go into shock and experience seizures or become comatose. People with Addisonian crisis need to have their cortisol replaced immediately with an injection of hydrocortisone.
Lack of cortisol is caused by damage to the adrenal glands, explains Healthline. Addisonian crisis is triggered by stress, such as trauma, surgery, dehydration, flu or a stomach virus.
