Bariatric surgery and pregnancy: impact, advantages and disadvantages, as well as timing

Obesity affects the reproductive health of women of reproductive age and meanwhile, increases the possibility of maternal and fetal complications. Bariatric surgery improves obesity-related fertility impairment. Traditional treatment methods such as exercise, diet, and medications all have limitations. Bariatric surgery is currently the most effective and lasting treatment for obesity, which can significantly improve obesity-related complications while achieving weight loss. With more and more obese women of childbearing age undergoing bariatric surgery, post-bariatric pregnancy has attracted increasing attentions from the academic societies. However, only a few studies have evaluated the effect of bariatric surgery on pregnancy-related outcomes, and the relevant literature is even scarce in China. Here, the authors summarize the impact of bariatric surgery on pregnancy-related results and the appropriate timing of post-bariatric pregnancy, so as to help guide the management of pregnancy-related events before and after bariatric surgery and obtain the best pregnancy outcomes.
