Maternal bariatric surgery: adverse outcomes in neonates
- 610 Downloads
The obesity epidemic in developed countries has led to an increased prevalence of obese women of reproductive age. As maternal obesity has far-reaching consequences for both mother and child, the consensus is that weight loss before pregnancy will reduce obesity-related morbidity and mortality. Therefore, an increasing number of women become pregnant after undergoing obesity surgery.
Results and discussion
From the literature, data shows that perinatal outcome after bariatric surgery is generally considered as favourable for both mother and child. Only a few case reports highlight the possibility of side effects on the foetus and neonate. We report on five cases with severe intracranial bleeding, all possibly related to vitamin K deficiency following maternal bariatric surgery.
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.
