Editor’s note: Given that obesity has now reached epidemic proportions in the US, rates of surgical weight-loss procedures have steeply increased, and many of these patients undergoing such surgery are women. The present authors aimed to estimate the incidence of bariatric surgery in women aged 18–45 years in the US and to review published pregnancy and fertility outcomes after surgery. This study involved a well-conducted systematic review of published literature, using appropriate methods for searching, study selection and inclusion, data abstraction, and analysis.
