Chronic fatigue syndrome (CFS) is a complicated disorder characterized by extreme fatigue that can’t be explained by any underlying medical condition. The fatigue may worsen with physical or mental activity, but doesn’t improve with rest.
This condition is also known as systemic exertion intolerance disease (SEID) or myalgic encephalomyelitis (ME). Sometimes it’s abbreviated as ME/CFS.(Information from Mayo Clinic)
Typically, for an official diagnosis of CFS, an individual must have been sick for six (6) or more months with fatigue severe enough to reduce the individuals activity level by at least 50% and at least four of the following symptoms: impairment in short-term memory or concentration, sore throat, tender lymph nodes, muscle or multi-joint pain without swelling or redness, headaches, unrefreshing sleep, and post-exertional malaise. Physicians must rule out other causes of the symptoms.
