Pregnancy after bariatric surgery: no problem?

Bariatric surgery is highly effective for weight loss in morbid obesity. With the high prevalence of severe obesity in the developed world, and the acknowledgement of the effectiveness of these procedures by National Institute for Clinical Excellence (in the UK) and the Food and Drug Administration (in the USA), women with severe obesity will increasingly seek such treatment. As the majority of these patients are women of reproductive age, obstetricians will encounter these patients frequently during pregnancy. It is therefore important for obstetricians to gain an insight into the types of surgery performed, the potential complications, including nutritional deficiency, and appropriate management of pregnancy following weight-loss surgery. In general, bariatric surgery is associated with a reduction in obesity related complication, with no apparent increased risk of adverse perinatal outcomes.
