Adrenal insufficiency means hypo-function of the adrenal cortex, usually glucocorticoid, may be associated with mineralocorticoid and rarely adrenal androgen. It can be categorized into two types: Primary adrenal insufficiency, or Addison's disease (cortisol low and ACTH high) or secondary/ tertiary adrenal insufficiency due to pituitary or hypothalamic disorders (both cortisol and ACTH are low). Identification of etiology is very important for plan of treatment. The reported incidence of adrenal insufficiency varies greatly depending on the population studied, the test and cut off levels used, and the cause. Many patients may present with adrenal crisis, some of them have subtle symptoms, hyperpigmentation, hypotension, electrolyte imbalance, shock etc.
Many of them have iatrogenic adrenal insufficiency with
IntroductionAdrenal insufficiency means hypo-function of the adrenal cortex usually glucocorticoid (cortisol) insufficiency. This may be associated with mineralocorticoid (aldosterone) and androgen (DHEAS) insufficiency. The clinical features are usually variable depending on whether the onset is acute, chronic or with adrenal crisis. 1 Adrenal crisis should be considered when patients present with vascular collapse (shock) whether or not known to have adrenal insufficiency. Sometimes these patients are having features of Cushing's syndrome due to chronic steroid use. Some of the patients may present with non-specific symptoms (like fatigue, weakness, anorexia, weakness) etc. Unexplained hyponatremia, hypoglycemia, weight loss should be suspected for chronic adrenal insufficiency.
