[Biomedical and psychosocial treatment of fatigue in functional somatic syndrome].

Fatigue is one of the most common complaints of patients with functional somatic syndrome (FSS), which includes chronic fatigue syndrome (CFS). Although the etiology of fatigue related to FSS remains unclear, accumulating evidence has shown that cognitive behavioral therapy and graded exercise therapy are effective for treating fatigue in patients with CFS. This suggests that psychosocial intervention and physical rehabilitation, as well as biomedical treatment, play an important role in treating fatigue in FSS patients. Here we provide an overview of the biomedical and psychosocial treatments for fatigue in cases of FSS.
