Lethargy

Lethargy: Introduction

Lethargy is a fairly imprecise description of the feeling or slowness, sluggishness, tiredness, or lack of energy. Lethargy in common usage may mean many things, including fatigue, drowsiness (sleepiness), lethargy, tiredness, malaise, listlessness, or weakness (including muscular weakness). The causes of these other similar symptoms also need to be investigated in researching a symptom of lethargy. Nevertheless, any type of lethargy symptom can indicate a serious medical condition and needs prompt medical investigation.

Diagnosis Checklist: Questions your doctor may ask (and why!)

During a consultation, your doctor will use various techniques in their assessment of Lethargy. Your doctor may ask several questions when assessing your condition. It is important to remember that your consultation is a two-way process and any extra information you can share with your doctor about your symptoms may help them with their diagnosis. Some of the questions your doctor may ask are listed below:

  • How long have you felt lethargic? - to determine if acute or chronic.
  • Explain what you mean by lethargy? - Lethargy is a fairly imprecise description of the feeling or slowness, sluggishness, tiredness, or lack of energy. Lethargy in common usage may mean many things, including fatigue, drowsiness (sleepiness), lethargy, tiredness, malaise, listlessness, or weakness (including muscular weakness).
  • Is the lethargy intermittent or constant? - Intermittent fatigue may suggest myasthenia gravis. Constant lethargy may be due to any of the other disorders, however if not associated with weight loss should consider a psychiatric disorder.
  • Are there simple reasons to explain lethargy? - e.g. not getting enough sleep, sleep debt, shift work, jet lag and boredom.
  • What is the quality of your sleep? - e.g. insomnia, obstructive sleep apnea, narcolepsy. Sleep disturbance is a common cause of lethargy.

  • Polyuria (excessive urination)? - may suggest hyperthyroidism, diabetes mellitus, hyperparathyroidism and chronic renal failure.
  • Orthopnea (breathlessness lying down flat)? - suggests left ventricular heart failure.
