Bariatric surgery: Impact on pregnancy outcomes

Research output: Contribution to journalArticlepeer-review


The dramatic increase in the prevalence of obesity in women of reproductive age has resulted in approximately 1 in 5 women being obese when they conceive. Bariatric surgery has been shown to be the most effective long-term weight loss strategy in obese women in this age group. Clinicians should be aware of the effects of bariatric surgery on fertility and future pregnancies. Regarding certain complications, pregnancy after bariatric surgery appears to be safer than pregnancy in the obese. In patients where nutrition is properly maintained and monitored, the risks for obesity-related obstetric complications, such as gestational diabetes mellitus and hypertension, are significantly reduced, but possibly at the expense of an increase in neonates born small-for-gestational- age. At the present, definitive conclusions cannot be drawn concerning the risk for Caesarian delivery, differences in type of bariatric procedure, or the optimal surgery-to-conception interval.
