Q

Tiredness - Diagnostic Tips

A

Diagnostic tips

  • Be alert to depression including masked depression.
  • Ask the patient what they believe is the cause of their tiredness.
  • Be alert for the classic endocrine traps: hypothyroidism and Addison disease.
  • Tiredness in absence of red flags is unlikely to have an organic cause.
  • Investigations are likely to be therapeutic and reassuring rather than diagnostic.
  • Learn how to undertake a brief, good physical examination and practise effective time management.
  • Do not overlook a sleep disorder.
  • Believe the patient’s symptoms.
