Chronic Fatigue Syndrome Causes

Chronic fatigue syndrome causes are not exactly known but a combination of factors have been studied and considered.


Some viruses could have triggered chronic fatigue syndrome since some individuals experience chronic fatigue syndrome after having a viral infection. Some suspected virus are the Epstein-Barr virus, the mouse leukemia virus and the human herpes virus 6. However, there are still no conclusive findings that will link these viruses with CFS.

Other viruses that could have triggered CFS is the Ross river virus which is a mosquito borne tropical diseases, the human retrovirus, mycoplasma which is the cause of atypical pneumonia, rubella or German measles and Candida alibicans which causes yeast infection.

Immune system

Immune system problems are also considered as one of the Chronic fatigue syndrome causes. people with chronic fatigue syndrome are also observed to have abnormal blood levels of hormones generated in the hypothalamahs, adrenal glands or pituitary glands. However, the significance or contribution of these abnormalities to CFS is still unsure.

Central nervous system

CFS is a medical condition by which a person experiences extended severe tiredness or fatigue which does not go away even after resting or bed rest and which has lasted for six months. The severity of the patient’s tiredness is enough to hinder his or her capability to perform daily activities at home or at work by a high 50 percent.

Doctors have also been studying the relationship of the central nervous system, stress, immune system and the activation of a latent virus as contributing factors. An inflammation of the nervous system has also been considered as a cause of CFS. Genetics, age, environment and prior illness could also play a role in aggravating chronic fatigue syndrome.

Other factors

Women at the 30 to 50 age bracket are at risk of being affected by CFS.

People who are inactive and are overweight are also more likely to suffer from CFS.
