[Iron deficiency and pregnancy after gastric bypass surgery].
In Denmark, the number of women in reproductive age having Roux-en-Y gastric bypass surgery increased in the period 2007-2010. The malabsorption related to the operation implies a predisposition to macro- and micronutrient deficiencies, which in pregnancy may influence the development of the foetus. The article concerns the need for managing the malabsorption syndrome, iron deficiency in particular, both in antenatal care, during pregnancy, delivery and in the lactation period. We suggest frequent follow-up in these patients and intravenous iron therapy, when oral iron treatment is inadequate.
