Ibiebele I, et al. - The population of women having bariatric surgery was described and the pregnancy outcomes for women having bariatric surgery vs a non-bariatric surgery population having a first and second pregnancy were assessed. In this population-based record linkage study, researchers assessed data of all women aged 15–45 years with a hospital record in New South Wales (NSW) (2002–2014) and all women giving birth in NSW (1994–2015; n = 1,606,737 women). During 2002–2014, a 13-fold increase in hospitalizations was observed for primary bariatric surgery. Women who had bariatric surgery vs the general birthing population experienced higher rates of hypertension, diabetes, and preterm birth. Among women who had bariatric surgery between a first and second pregnancy, reductions in obesity-related adverse pregnancy outcomes were observed in the second pregnancy. Improved pregnancy outcomes in a subsequent pregnancy were achieved in correlation to undergoing bariatric surgery for the management of obesity in accordance with current clinical criteria.
