- Primary
- Causes
- Autoimmune (associated with other endocrinopathies, PTH, DM)
- Infection (TB, viral, meningococcemia)
- Infiltration (sarcoidosis, amyloidosis)
- Hemorrhage (trauma, anti-coagulation)
- Malignancy (primary, metastatic)

- GI: anorexia, nausea/vomiting, diarrhea
- Hyperpigmentation
- Labs
- Hyponatremia
- Hyperkalemia
- Hypercalcemia

- Causes
- Secondary
- Causes
- Iatrogenic (>5mg prednisone/day for > 2 weeks)
- Pituitary/sellar tumors
- Hemorrhage (Sheehan)
- Cranial radiation
- Signs/Symptoms
- RAAS function maintained, hypotension rare
- Features of pituitary/hypothalamic dysfunction: menstrual disturbances, headache, vision changes, galactorrhea, acromegaly
- Causes
- Adrenal Crisis
- Precipitated by physiologic stressor: sepsis, MI, trauma, surgery
- Diagnosis
- AM cortisol <3
- ACTH stimulation peak cortisol <15
- ACTH level
- Management
