Adrenal crisis
Adrenal crisis is a potentially life-threatening medical condition requiring immediate emergency treatment. It is a constellation of symptoms (caused by insufficient levels of the hormone cortisol) that indicate severe adrenal insufficiency. This may be the result of either previously undiagnosed or untreated Addison's disease, a disease process suddenly affecting adrenal function (such as bleeding from the adrenal glands in Waterhouse–Friderichsen syndrome), suddenly stopping intake of glucocorticoids or an intercurrent problem (e.g. infection, trauma, in fact any form of physical or mental stress) in someone known to have Addison's disease, congenital adrenal hyperplasia (CAH), or other form of primary adrenal insufficiency. Characteristic symptoms are: Sudden penetrating pain in the legs, lower back or abdomen Confusion, psychosis, slurred speech Severe lethargy and generally "not feeling well" Convulsions Fever Hyperkalemia (elevated potassium level in the blood) Hypercalcemia (elevated calcium level in the blood): the cause of hypercalcemia is a combination of increased calcium input into the extracellular space and reduced calcium removal by the kidney, this last caused by decreased glomerular filtration and increased tubular calcium reabsorption. Both renal factors are secondary to volume depletion and, in fact, improve rapidly during rehydration with saline infusion. Hypoglycemia (reduced level of blood glucose) Hyponatremia (low sodium level in the blood) Hypotension (low blood pressure) Hypothyroidism (low T4 level) Severe vomiting and diarrhea, resulting in dehydration Syncope (transient loss of consciousness) and/or orthostatic hypotension (drop in blood pressure on standing, leading to loss of balance) Adrenal crisis is caused by a deficiency of cortisol resulting from Addison's disease, congenital adrenal hyperplasia (CAH), corticosteroid biosynthetic enzyme defects or pituitary disorders (such as Sheehan's syndrome, pituitary adenoma, hypopituitarism (inactive or underactive pituitary) causing failure to activate the adrenal glands.
