Weight-loss surgery tied to pregnancy benefits, risks

By Andrew M. Seaman (Reuters Health) – - Weight loss surgery may reduce some of the pregnancy risks associated with obesity, but it could also put women and their infants at greater risk for other problems, according to a new study in Sweden. Compared to obese women who didn't have so-called bariatric surgery, women who did were less likely to develop diabetes during pregnancy and less likely to deliver overly large babies, researchers report in The New England Journal of Medicine. Bariatric surgery "has both positive and negative influences on the risk of complications during a subsequent pregnancy,” said Kari Johansson, the study’s lead author from the Karolinska Institute in Stockholm. Johansson cautioned in her email to Reuters Health that the study shows ties between weight-loss surgery and pregnancy outcomes, but doesn’t prove cause and effect.
