We identified pregnant females aged \u226518 between June 1, 2015, and June 25, 2025. Patients with prior bariatric surgery were identified using ICD-10 and CPT codes. Propensity score matching (1:1) was performed based on age, race, ethnicity, gravida, parity, hypertension, diabetes, anemia, and delivery method, yielding 41\u00a0777 matched pairs. Perinatal outcomes including fetal growth restriction (FGR), macrosomia, gestational hypertension, gestational diabetes, preeclampsia, and preterm delivery were compared using odds ratios (ORs) and 95% confidence intervals (CIs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Bariatric surgery was associated with significantly lower risks of FGR (OR 0.831, 95% CI 0.749-0.921), macrosomia (OR 0.283, 95% CI 0.262-0.305), gestational hypertension (OR 0.391, 95% CI 0.375-0.409), preeclampsia (OR 0.313, 95% CI 0.294-0.334), gestational diabetes (OR 0.415, 95% CI 0.393-0.439), and preterm delivery (OR 0.525, 95% CI 0.493-0.560) compared to controls.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Patients with a history of bariatric surgery who became pregnant after the procedure experienced significantly reduced risks of several adverse perinatal outcomes.
