[Towards a unified treatment approach for functional somatic syndromes and somatization].

Identical treatment strategies have proven effective in various functional somatic syndromes (FSS) and evidence is increasing that FSS share common aetiological factors, pathophysiological mechanisms and psychological features. Currently, only a minority of patients with FSS receive evidence-based treatment. The main reasons for this are inappropriate organisation of care, physicians' lack of knowledge and a widespread neglect of patients' suffering. We outline a unified stepped care approach for the prevention and management of FSS in which treatment strategies are not based on the diagnostic label, but on illness severity and complexity.
