This review examines how the body produces and uses energy in people with ME/CFS. Research suggests that people with ME/CFS have problems with how their bodies break down food and nutrients for energy, and their cells may not be using their energy factories (mitochondria) efficiently. The review highlights that metabolomics—a technique that measures thousands of molecules in the body at once—could be a powerful tool for understanding what goes wrong in ME/CFS.
Understanding the metabolic basis of ME/CFS is critical because it may explain the persistent fatigue and multi-system symptoms that define the condition. Metabolomics offers a systematic way to identify what is actually different in ME/CFS patients' biochemistry, which could eventually lead to better diagnostic tests and targeted treatments. This review emphasizes that the answer likely lies in measuring many metabolic molecules simultaneously, not just looking at single pathways.
This review does not prove cause-and-effect relationships—it identifies metabolic abnormalities but does not establish whether they cause ME/CFS symptoms or result from them. The review also does not demonstrate that any single metabolic pathway is uniquely responsible for the disease. Furthermore, as a review of existing studies with varying diagnostic definitions, it does not establish what the core metabolic defect is or how to treat it.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
