Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a relatively common illness, yet despite considerable investigation, current treatments have modest benefits, and the prognosis remains poor. Because CFS/ME is a heterogeneous disorder with diverse etiological factors and pathological features, a patient-centered integrative framework based on modifiable physiological and environmental factors may offer hope for more effective management and better clinical outcomes. An individualized approach may also help target interventions for subgroups most likely to respond to specific treatments. This review summarizes a number of avenues for integrative management, including dietary modification, functional nutritional deficiencies, physical fitness, psychological and physical stress, environmental toxicity, gastrointestinal disturbances, immunological aberrations, inflammation, oxidative stress, and mitochondrial dysfunction. A personalized, integrative approach to CFS/ME deserves further consideration as a template for patient management and future research.
