The increasing prevalence of morbid obesity in our Western society has led to the development of multiple bariatric operations. Women in the reproductive age represent an important part of this patient population: to avoid fertility problems and pregnancy related complications, a preconception decrease in BMI is crucial.
The literature regarding pregnancy outcome following bariatric surgery is generally positive, although it is scarse and consists mainly of relatively small surgical series. Only a minority of the case reports concerns the possible negative side effects towards the fetus and neonate.
We describe 5 cases of severe neonatal complications related to vitamin K deficiency following maternal bariatric surgery.
We found no other reports on maternal or neonatal vitamin K deficiency after maternal bariatric surgery. Our cases indicate that pregnancies following bariatric surgery are at high risk and these patients need specialised multidisciplinary follow up before, during and after delivery.
