Chronic Fatigue Syndrome
(CFS; Chronic Fatigue and Immune Dysfunction Syndrome)
DefinitionChronic fatigue syndrome (CFS) is a condition that causes chronic, debilitating fatigue. It continues for at least 6 months. The fatigue is not relieved by bed rest. People who have CFS perform at a significantly lower level compared to their activity prior to the onset of the illness.
CausesThe cause of CFS is unknown. Some believe there may be a link between CFS and stress, the immune system, toxins, the central nervous system, or activation of latent virus.
