This study looked at four adolescent patients who had both an eating disorder and ME/CFS at the same time. In all four cases, the eating disorder appeared first, followed later by ME/CFS symptoms. The authors explored whether these two conditions might be related through common causes, whether an eating disorder could trigger ME/CFS, or whether they simply occurred together by chance.
This study highlights an important and underexplored comorbidity pattern in adolescents with ME/CFS. Understanding potential connections between eating disorders and ME/CFS could improve clinical recognition and treatment approaches for patients presenting with both conditions, particularly given the shared cardiovascular and psychological features identified.
This small case series cannot establish whether eating disorders cause ME/CFS, are merely coincidental, or share common underlying causes. The temporal sequence observed does not prove causation, and findings from four cases cannot be generalized to the broader ME/CFS or eating disorder populations. No control group comparison means we cannot determine if this comorbidity occurs more frequently than expected by chance.
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 →
