Chronic Fatigue Syndrome
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. The cause of chronic fatigue syndrome is unknown, although there are many theories — ranging from viral infections to psychological stress. Some experts believe chronic fatigue syndrome might be triggered by a combination of factors. There's no single test to confirm a diagnosis of chronic fatigue syndrome. You may need a variety of medical tests to rule out other health problems that have similar symptoms. Treatment for chronic fatigue syndrome focuses on symptom relief.
