Understanding Chronic Fatigue Syndrome

Chronic fatigue disorder is a disorder that is characterized by extreme fatigue that does not seem to be caused by any medical condition. The fatigue does not improve with rest and may become worse with both mental and physical activity. Although it is unknown what causes chronic fatigue syndrome, some theories include improper diet, hormonal imbalance, thyroid problems, physiological stress, viral infections or a combination of many factors. Chronic fatigue syndrome does not necessarily use a specific test to determine its diagnosis. A ruling out of other tests with diseases that have similar symptoms may be the best way to get a diagnosis.
