Abstract

BACKGROUND:

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.

CONCLUSION:

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.
