Adrenal insufficiency.
Adrenocortical insufficiency may arise through primary failure of the adrenal glands or due to lack of ACTH stimulation as a result of pituitary or hypothalamic dysfunction. Prolonged administration of exogenous steroids will suppress the hypothalamic-pituitary-adrenal axis, and hence cortisol secretion. We review briefly the causes, investigation, and treatment of adrenal insufficiency, and highlight aspects of particular relevance to patients with adrenal tumors.
