About 50% of those that suffer with fatigue also have depression, anxiety or other mental/emotional stress. Chronic fatigue is a associated with a wide-range of other conditions. Determining the cause of fatigue requires a complete medical history including the duration of the fatigue, the associated symptoms and the nature of the symptoms.

  • Blood Tests including a CBC, urinalysis, Blood Glucose, ESR, tests for human immunodeficiency virus (HIV), purified protein derivative, Thyroid Panel, [Electrolytes|Serum electrolytes]]
  • Other Tests which may be considered include a chest radiograph, tuberculin test, monospot test or a sleep study.

Naturopathic Treatment

The goal of naturopathic treatment is to support and work in tandem with the healing power of the body and to address the causal factors of disease with individual treatment strategies. Fatigue is typically treated by treating the condition or conditions that it is associated with.

It is always advisable to work with a naturopathic doctor before engaging in any treatment plan.
