(Adrenocortical insufficiency/Addisonian crisis) is a form of Addison's disease that is caused by damage or dysfunction of the adrenal cortex, which then leads to low levels of aldosterone and cortisol.

Adrenocortical insufficiency

___________________________ is also known as a provocation Test. The patient is given an infusion of ACTH and then we measure cortisol levels at 30 minutes and 1 hour intervals.

The adrenal (medulla/cortex) hormones are the salt sugar and sex hormones and include the following: ~ Mineralocorticoids: Aldosterone increases sodium absorption and causes potassium excretion in the kidneys ~ Glucocorticoids: Cortisol affects glucose, protein, and fat metabolism. Impacts the body's response to stress. Impacts the body's immune function. ~ Sex hormones: Androgens and estrogens, which influence sex characteristics, fertility, and maintenance of overall health.

Cortex

Adrenal crisis can be a life threatening complication of _______________ if hormones like corticosteroids are not replaced when the body can't produce its own

Decreased

Diabetes insipidus (Dry Inside)is a condition of ADH (excess/deficiency) wherein the kidneys will not collect and concentrate urine, causing dilute urine with high output

Deficiency

Dose of steroids (dexamethasone) is administered, and then the body's response is measured based on cortisol excretion over the next 24 hours. Can measure cortisol levels in blood and urine. •24 hour urine will show low cortisol secretion if the person does not have Cushing's •If the secretion is not suppressed by the steroid dose and the cortisol levels are the same despite taking the dexamethasone, it indicates Cushing's. This test is called _____________________________

Dexamethasone suppression test
