What causes Chronic Fatigue Syndrome?

Causes: Chronic Fatigue Syndrome: CFS seems to involve interactions between the immune and central nervous systems, interactions about which scientists know relatively little. Scientists' concerted efforts to penetrate the complex nervous system and immune system events in CFS have created a challenging new concept of the pathology of this and other illnesses.

Article excerpts about the causes of Chronic Fatigue Syndrome:
While no one knows what causes CFS, for more than a century, doctors have reported seeing illnesses similar to it. In the l860s, Dr. George Beard named the syndrome neurasthenia because he thought it was a nervous disorder with weakness and fatigue. Since then, health experts have suggested other explanations for this baffling illness.

  • Iron-poor blood (anemia)
  • Low blood sugar (hypoglycemia)
  • Environmental allergy
  • A body wide yeast infection (candidiasis)
In the mid-1980s, the illness became labeled "chronic EBV" when laboratory clues led scientists to wonder whether the Epstein-Barr virus (EBV) might be causing this group of symptoms. New evidence soon cast doubt on the theory that EBV could be the only thing causing CFS. High levels of EBV antibodies (disease-fighting proteins) have now been found in some healthy people as well as in some people with CFS. Likewise, some people who donít have EBV antibodies, and who thus have never been infected with the virus, can show CFS symptoms.
