What is Adrenal crisis?

Adrenal crisis is a potentially life-threatening medical condition requiring immediate emergency treatment. It is a constellation of symptoms that indicate severe adrenal insufficiency caused by insufficient levels of the hormone cortisol. This may be the result of either previously undiagnosed or untreated Addison's disease, a disease process suddenly affecting adrenal function , suddenly stopping intake of glucocorticoids or an intercurrent problem in someone known to have Addison's disease, congenital adrenal hyperplasia , or other form of primary adrenal insufficiency.
