Chronic fatigue syndrome is a very insidious disease. It can come on suddenly or gradually. Its symptoms can mimic other diseases and disorders. Despite the volumes of literature investigating it, no one is entirely sure of its cause. Even the name is misleading. "Fatigue" is not a disease, but a normal recovery period from exertion. Chronic fatigue syndrome, however, involves a total physical, mental and emotional exhaustion that is not relieved by rest and can be completely incapacitating.
Theories regarding the etiology of CFS abound. Some believe it is a result of an inner-ear disruption, others that it has its root in dental infections, hormonal dysfunction, metabolic disorders, spinal problems or disruption of the autonomic nervous system. A cluster of anecdotal and laboratory evidence, however, seems to point to a malfunctioning immune system as a likely cause.
The onset of CFS often seems to follow a period of high stress or a viral or bacterial infection, thus implicating the immune system. However, it isn't known whether the system is overreacting or under reacting, making treatment problematic. In either case, strengthening and modulating the immune system may provide relief from CFS symptoms.
