Bariatric surgery linked to menstrual regularization and reduced PCOS prevalence in obese women
Observational data show bariatric surgery improves menstrual regularity and reduces PCOS markers in obese women, yet small sample size and absent randomization limit causal claims. Holistic preconception care and longer-term offspring follow-up are needed to translate these signals into practice.
Next steps require multicenter RCTs comparing surgery to GLP-1 agonists on fertility endpoints, live-birth rates, and offspring metabolic outcomes through age five. Funding should prioritize diverse ethnic cohorts where PCOS phenotypes differ. Until then, clinicians should embed reproductive endocrinology review before and after bariatric referral rather than treating menstrual improvement as incidental.
University of Surrey team: Within 36 months, at least two UK fertility clinics will adopt mandatory reproductive counseling protocols for bariatric patients, measured by 50% uptake in audit data.
