Does not affect weight loss

摘要

Maternal obesity increases the risk of pregnancy complications, and rates of adverse maternal and neonatal outcomes are lower after bariatric surgery. Although women are advised to avoid pregnancy for 12-24 months after bariatric surgery owing to fears of fetal undemutrition and reduced weight loss benefits, little is known of the effects of a subsequent pregnancy on weight loss.We identified 232 women of childbearing age (18-45 years) who had undergone bariatric surgery (197 gastric bypass, 19 gastric banding, eight sleeve gastrectomy, and eight other procedures). Mean age was 34.0 years, preoperative weight 137.7 kg, and body mass index (BMI) 50.6.
