Chronic fatigue syndrome (CFS or CFS/ME)

Chronic fatigue syndrome (CFS or CFS/ME) G93.3. CFS is commonly referred to as (benign) myalgic encephalomyelitis (encephalopathy) or ME.

A range or spectrum of disorders exists, characterized by abnormal levels of and unusual types of fatigue, along with other features and symptoms. Whether these represent distinct entities or variations on a common theme is uncertain. Aetiology and pathogenesis are not always known. Terminology is therefore problematic.
