Summary of ME/CFS

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is an illness characterized by profound, severe fatigue lasting at least six months that gets worse with exhertion and which sleep doesn't alleviate. It has gone by many other names in the past, including systemic exertion intolerance disease (SEID), myalgic encephalomyelitis, and chronic fatigue and immune dysfunction syndrome (CFIDS), none of which should be confused with the mythical diagnosis of adrenal fatigue. ME/CFS is thought to afflict 0.26 to 0.78%[1] of the U.S. population, roughly 800,000 to 2.5 million people. The causes of this syndrome have been hotly debated.
