Chronic fatigue syndrome, or CFS, is a devastating and complex disorder characterized by overwhelming fatigue that is not improved by bed rest and that may be worsened by physical or mental activity. People with CFS most often function at a significantly lower level of activity than they were capable of before the onset of illness.
In addition to these key defining characteristics, patients report various nonspecific symptoms, including weakness, muscle pain, impaired memory and/or mental concentration, insomnia, and post-exertional fatigue lasting more than 24 hours. In some cases, CFS can persist for years.
CFS is the result of poor cellular mitochondrial function resulting from a combination of nutritional deficiencies, toxicities, infectious agents and even food allergies. The mitochondria are considered the power factory for each cell. If they cannot burn fuel properly, that particular cell will not do its job correctly whether it be a brain, pancreas, heart or colon cell. If many of the bodies cells have this problem, CFS is one of a multitude of symptoms and conditions that may develope.
