Key questions to ask
- Has this person had prolonged steroids in the last 6 months?
- Does this patient have postural hypotension?
- Are they losing weight unintentionally?
- Do they have low/borderline blood sodium?
- Do they have salt, soy sauce or liquorice cravings, or increased thirst and urination?
- Do they have appropriate pigmentation, or has there been a change in skin colour? (primary adrenal insufficiency only)
- Is there a history of endocrine or autoimmune conditions, such as thyroid disorders,
Type 1 diabetes, B12 deficiency or coeliac disease in the extended family
Screening
- Where the patient is stable, the GP should assess for clinical signs, especially:
Blood pressure sitting and standing. A 20mmHg drop on standing indicates clear postural hypotension. - Proximal myopathy or global muscle weakness (difficulty climbing stairs, getting up from a sitting/squatting position, or carrying weights, such as grocery shopping).
- Patchy hyperpigmentation or, in Caucasians, unusual pigmentation in the palmar/wrist creases (not present in 20% of cases, depending on the patient’s natural level of melanocytes). Hyperpigmentation is typically most obvious in areas of increased friction, such as the oral mucosa, knuckles, elbows or waistline
NOTE: If adrenal crisis is suspected, NEVER delay emergency treatment to perform investigations.
