Objectives: Obesity negatively affects female fertility and pregnancy outcomes. Bariatric surgery improves weight, metabolism, and fertility, but concerns remain about maternal and neonatal outcomes. To evaluate reproductive and perinatal outcomes in Polish women who conceived after bariatric surgery (MOMBARIS 2). Material and methods: A retrospective study (2015–2024) in 11 bariatric centers included 160 women post-surgery; 154 conceived and were analyzed for fertility, pregnancy, and neonatal outcomes. Results: Pregnancy occurred in 97.5% of participants, mostly spontaneous (83.8%) and planned (58.7%). BMI dropped from 43.1 to 30.45 kg/m². Complications: anemia (35.9%), gestational diabetes (16.2%), hypertension (10.2%). Cesarean rate: 52.7%. Neonatal outcomes were favorable: median birth weight 3,330 g, gestational age 39 weeks, 97.9% had Apgar 10, and 3.0% had anomalies. Conclusions: Despite maternal risks, neonatal outcomes were excellent. Bariatric surgery improves fertility without compromising fetal health.
