Study Links Endometriosis to Higher Type 2 Diabetes Risk
A retrospective cohort analysis published in *Diabetologia* (August 2026) examined Utah health records over 25 years. Researchers compared nearly 3 million women, including almost 100 000 with endometriosis, and found a 46 % higher likelihood of developing type 2 diabetes. The risk was most pronounced in women with extra-pelvic disease, premenopausal women, and those who were not obese.
Background & Context
Endometriosis affects about one in ten women of reproductive age and involves tissue similar to the uterine lining growing outside the uterus, causing chronic pelvic pain and infertility. While traditionally viewed as a localized gynecological disorder, it is increasingly recognized as a systemic inflammatory condition that may influence metabolic pathways.
Data & Statistics
- Study population: ~3 million women, 1996-2021.
- Women with endometriosis: ~100 000 (?3 % of cohort).
- Overall diabetes risk increase: 46 % higher relative risk.
- Strongest association: extra-pelvic endometriosis.
- Highest risk groups: premenopausal women and non-obese women.
Why It Matters
If confirmed, clinicians could use an endometriosis diagnosis—especially extra-pelvic disease—as a cue for earlier metabolic screening. Early detection of impaired glucose regulation may allow preventive interventions such as lifestyle counseling and cholesterol management before overt diabetes develops. The findings broaden the view of endometriosis as affecting whole-body health.
Official Statements & Responses
Lead author Maggie Fuzak Nunziato, a doctoral student in epidemiology at George Mason University, said the study adds to evidence that endometriosis impacts more than reproductive health. Co-author Anna Pollack, professor of Global and Community Health, highlighted the stronger link with extra-pelvic disease, suggesting a role for systemic inflammation. Stephanie Faubion, M.D., medical director for The Menopause Society, noted that type 2 diabetes can worsen menopausal symptoms, underscoring the relevance of metabolic health in midlife women.
Conflicting Reports & Gaps
The study relied on existing health records, limiting causal inference. Potential confounders include access to care, medication use, lifestyle, family history, and socioeconomic status. Timing and severity of endometriosis diagnoses may vary, and some cases could be undetected. The research did not measure inflammatory biomarkers or insulin-signaling pathways, leaving mechanisms speculative. Future longitudinal studies with laboratory measurements and detailed clinical data are needed to clarify the link and assess whether treating endometriosis alters diabetes risk.
