a·cute a·dre·no·cor·ti·cal in·suf·fi·cien·cy

severe adrenocortical insufficiency when an intercurrent illness or trauma causes an increased demand for adrenocortical hormones in a patient with adrenal insufficiency resulting from disease or use of relatively large amounts of similar hormones as therapy; characterized by nausea, vomiting, hypotension, and frequently hyperthemia, hyponatremia, hyperkalemia, and hypoglycemia; can be fatal if untreated. Death results from fulminant inflammation and/or circulatory collapses (that is, shock).

Acute Adrenal Crisis

Acute life-threatening adrenocortical insufficiency with markedly reduced serum cortisol, which arises in a background of chronic adrenocortical insufficiency (Addison’s disease).  
Aetiology Infections, trauma, adrenal haemorrhage, tuberculosis, surgery, dehydration with salt deprivation, destruction of pituitary gland or evoked by replacing thyroid hormone in patients with hypothyroidism of hypothalamic or pituitary origin and underlying mild ACTH deficiency.
Triggers GI infection, fever
Clinical findings Hypotension, shock, fever, dehydration, anorexia, weakness, apathy, headache, vomiting, chills, tachycardia, sweating, abdominal pain
Lab Reduced Na+, increased K+, increased white cells, eosinophilia, hypoglycaemia
Management Pharmacologic doses of IV hydrocortisone, pressor support
