Identifying the cause of fatigue

Most adults experience fatigue at some point, and it is usually related to insufficient and/or poor sleep.

If a patient develops an ongoing pattern of fatigue, there are a number of possible causes, that can be broadly categorised as follows:


Work Environment & Culture

  • Shift work
  • High stress or demanding work
  • Night work
  • Irregular work hours


  • Stress disorders (e.g. ASD, PTSD)
  • Anxiety
  • Depression


  • Anaemia
  • Urinary tract infection
  • Heart disease
  • Cancer

Sleep Disorders

  • Sleep apnea
  • Restless leg syndrome
  • Insomnia

Lifestyle factors

  • Use of alcohol & tobacco
  • Unhealthy eating habits
  • Medications, such as antihistamines and cough medicines
  • Lack of physical activity
  • Excess physical activity
