Breastfeeding in metabolic and bariatric patients: a comprehensive guide for surgeons, patients, and the multidisciplinary team.

Abstract

Since nearly 40% of metabolic and bariatric surgery (MBS) patients are individuals with the ability to bear children, many may seek to become pregnant or may be currently lactating when seeking surgery. While many patients plan to breastfeed, MBS patients are at high risk for premature cessation of breastfeeding. Limited literature exists on the impact of MBS on lactation and there are no established guidelines to help clinicians support and educate MBS patients about breastfeeding. Herein, we aim to fill that gap by providing a comprehensive guide for bariatric surgeons, obstetricians, women's health providers, lactation consultants, registered dietitians, bariatric nurse coordinators, and advanced practice providers to support breastfeeding in patients with a history of MBS or who are considering MBS. We review physician-patient discussion points on how MBS impacts lactation, the micronutrient and caloric needs for this unique population, and data to support successful breastfeeding in post-MBS patients who are lactating regarding practical, anesthetic, and imaging considerations.
