Fatigue Symptoms

Fatigue is a symptom that usually has some underlying cause. Fatigue may be described by people in different ways, and may include some combination of the following (both mental and physical):

  • weakness,
  • lack of energy,
  • constantly tired or exhausted,
  • lack of motivation,
  • difficulty concentrating, and/or
  • difficulty starting and completing tasks.

Other symptoms such as fainting or loss of consciousness (syncope), near-syncope, rapid heartbeat (palpitations), dizziness or vertigo may also be described as part of the fatigue experienced by the affected individual. The presence of these symptoms may actually help lead a health care practitioner to discover the underlying cause(s) of the fatigue.
