Maternal bariatric surgery: adverse outcomes in neonates

Abstract

These reports indicate that careful nutritional follow-up during pregnancy after obesity surgery is mandatory, because nutritional deficiencies such as vitamin K deficiency can lead to life-threatening bleeding.

Obstetrical and Neonatal Outcomes of Pregnancies following Gastric Bypass Surgery: A Retrospective Cohort Study in a French Referral Centre

“…The most common nutritional deficiencies after RYGBP are of protein, iron, calcium, and vitamins B12, D, and folic acid [31,43], which all could have an impact on pregnancy. An increased risk of anemia has been reported during pregnancy after RYGB [43,44], and five cases of neonatal intracranial bleeding, all possibly related to vitamin K deficiency, have been reported following maternal bariatric surgery [45]. In two studies, the incidence of neural tube defects after RYGBP was higher than expected [46,47].…”

A meta‐analysis of maternal and fetal outcomes of pregnancy after bariatric surgery

“…Obesity is associated with an increased risk of obstetric complications, such as gestational diabetes, pre-eclampsia, eclampsia, macrosomia, and fetal growth restriction [2,3]. Therefore, in view of the substantial increase in the prevalence of obesity among women of child-bearing age, a rise in the frequency of adverse maternal and fetal outcomes should be expected [4].…”

Is Restrictive Bariatric Surgery Good Option in Improving Pregnancy Outcome in Obese Women?

“…Women who have malabsorptive procedures might have deficiencies in iron, vitamin B12, or fat-soluble vitamins. Electrolyte abnormalities can result if recommended supplements are not taken or if the length of remaining small bowel is inadequate [16]. The National Institute for Health and Clinical Evidence concluded that; Surgery remains more effective than a non-surgical approach for people who are obese and weight loss after surgery has the potential to confer enormous health benefit for mother and child in the longer term (measured up to 10 years after surgery) [17].…”
