Primary - Adrenal Gland

Secondary - Pituitary

Iatrogenic - Result of Therapeutic Use of Corticosteroids

131
Q

Primary Addison’s Disease

A

partial or complete destruction of adrenal cells - 80-90% from autoimmune destruction from autoimmune adrenalitis

can also be due to infection of Tb or AIDS

result of therapeutic use of corticosteroids

suppressed adrenal gland release of glucocorticoids after only 2-4 weeks of steroid use

chronic steroid administration suppresses the HPS axis and eventually causes adrenal atrophy
