Background: Bariatric surgery presently is the best possible intervention for treatment of severe obesity and its related conditions. This study presents retrospective data on the pregnancy outcomes of Indian patients who underwent bariatric surgery before conception.

Methodology: This is a single-centre retrospective, observational study. Data on demographics, pre-surgery weight, body mass index (BMI), types of bariatric surgery, weight at conception, weight gain during pregnancy, type of delivery and the health of the baby were collected and analysed to study the weight loss pattern and pregnancy outcomes in female patients of childbearing potential.

Results: The study included 34 women of childbearing potential (BMI>30 kg/m2) who underwent bariatric surgery. The study population was followed up from the time of surgery until 1-year post-delivery of the baby. The mean weight gain during the pregnancy was 14.9±5.4 kg. Twenty-three underwent LSCS, and the rest had normal delivery with mean baby weight of 2.5±0.4 kg. Six babies required neonatal intensive care. In our series, only 4 of 35 cohorts that are only 11% had substantial weight retention (range 5-13 kg) at the end of 12 months which is significantly lower than the normal cohorts who did not undergo bariatric surgery.

Conclusion: Bariatric surgery improves fertility with safe pregnancy and its outcomes in terms of preeclampsia, eclampsia, gestational diabetes, premature rupture of the membranes (PROM), postpartum haemorrhage (PPH) and puerperal sepsis in women with childbearing potential and safe for offspring in terms of shoulder dystocia, macrosomia, birth asphyxia and perinatal mortality. However, they should be well aware of the risks associated with bariatric surgery especially the mal-absorptive procedures.
