This study looked at insurance claims from nearly 4 million people to understand how common endometriosis is and how much it costs to treat. Researchers found that women with endometriosis spend significantly more on medical care than other women, have frequent hospital stays and surgeries, and often have other health conditions at the same time—including chronic fatigue syndrome. The study shows endometriosis is a serious, expensive condition that affects many aspects of a woman's health.
This study is highly relevant to ME/CFS patients because it documents chronic fatigue syndrome as a significant comorbidity in endometriosis—occurring in 29% of women with endometriosis and associated with 29% higher healthcare costs. The paper demonstrates that ME/CFS often co-occurs with other chronic conditions (endometriosis, IBS, depression, migraine), suggesting shared pathophysiological mechanisms or diagnostic overlap that warrant investigation. Understanding the prevalence and cost burden of comorbid ME/CFS in other conditions may help validate ME/CFS as a serious medical illness and advance recognition of its complex clinical presentation.
This study does not establish causality between endometriosis and chronic fatigue syndrome—it only documents their co-occurrence in insurance claims. The cross-sectional design cannot determine whether ME/CFS causes endometriosis, endometriosis causes ME/CFS, or both share a common underlying mechanism. Additionally, claims-based diagnosis codes may misclassify or underdiagnose conditions, so the true prevalence of comorbidity cannot be determined from administrative data alone.
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 →
