Obesity continues to be a global epidemic, and strong evidence exists linking it with gestational complications such as macrosomia, hypertensive disorders of pregnancy, gestational diabetes, and cesarean section. Bariatric surgery, a highly effective treatment for obesity, may prevent such complications in subsequent pregnancies.
This review seeks to describe the risks and benefits of post-bariatric procedure pregnancies, in comparison to both community and obese cohorts.
A thorough review of the literature suggests that post-surgery women are not at increased risk for poor perinatal outcomes, and moreover their risks for many obesity-related gestational complications are reduced after bariatric surgery. Data regarding fertility after bariatric surgery are quite ambiguous, however, and studies exist demonstrating both positive and negative associations between weight loss procedures and fertility.
Clinicians should be aware that data collected on this subject were often gathered from post-op pregnant women provided with good prenatal care and screening for nutritional deficiencies. Although pregnancy after bariatric surgery appears to be safe, providers should take extra care to properly monitor their post-op pregnant patients for appropriate weight gain and nourishment.
