This study looked at three patients who were diagnosed with ME/CFS but also had eating disorders (anorexia nervosa or bulimia nervosa). The doctors found that proper screening for eating disorders is important because patients and families may focus on the ME/CFS diagnosis and miss the eating disorder, which delays appropriate treatment. Early identification of both conditions together can help reduce serious health problems.
This work highlights an important diagnostic challenge: eating disorders can co-occur with or be misattributed as ME/CFS, potentially leading to delayed appropriate treatment. For ME/CFS patients and their families, understanding this connection emphasizes the importance of comprehensive psychiatric screening alongside medical evaluation to ensure accurate diagnosis and effective management.
This study does not prove that eating disorders cause ME/CFS or vice versa, nor does it establish prevalence rates of comorbidity. As case vignettes rather than a population-based study, the findings cannot be generalized to the broader ME/CFS population. The study also does not address whether ME/CFS symptoms might be secondary to or confused with eating disorder symptoms.
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 →
