This study found that people with ME/CFS have a higher risk of breaking bones compared to people without ME/CFS. Researchers followed nearly 4,000 patients with ME/CFS and about 15,000 without the condition over several years and found that fractures occurred more frequently in the ME/CFS group. Interestingly, this increased fracture risk did not appear to be mainly caused by weakened bones (osteoporosis), suggesting a different mechanism may be at play.
This study identifies fracture risk as a previously underrecognized medical complication of ME/CFS that clinicians should monitor. It suggests that ME/CFS-related fracture vulnerability operates through mechanisms beyond osteoporosis, opening avenues for investigation into how the condition affects bone quality, metabolism, physical activity, or other physiological parameters that may increase fracture susceptibility.
This study cannot establish causation—it demonstrates association only. It does not explain the biological mechanism underlying increased fracture risk in ME/CFS. The study also does not determine whether increased fractures result directly from ME/CFS pathophysiology, functional limitations, activity restrictions, or other coexisting factors. Finally, results from a Taiwan-based cohort may not be fully generalizable to other populations.
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 →
