Reproductive implications of bariatric surgery: Pre- and postoperative considerations for extremely obese women of childbearing age

Extreme obesity remains a frustrating and formidable disease, with most sufferers requiring surgical intervention in order to achieve long-term, sustained weight loss. Most bariatric procedures today are performed on women, many of whom are of reproductive age; yet minimal evidence exists to guide clinicians in the care of such women before, during, and after pregnancy. This review outlines the fundamental nutritional and surgical alterations of the most commonly performed bariatric procedures with the aim to elucidate a physiologically sound approach to counseling and management of extremely obese women of childbearing age who are either contemplating or have already undergone bariatric surgery. Preconception, pregnancy, and lactation guidelines are offered based on available evidence. Outstanding questions are highlighted for further investigation.
