Zwangerschap na bariatrie Zwangerschapsuitkomsten en diabetes gravidarum

(2018) Duijn, L. van (Liesbeth)

Introduction: Globally the rates of obesity are increasing; this includes women in their reproductive years. An effective method for treating obesity is bariatric surgery. This combination leads to more pregnancies in women who have had bariatric surgery. Research has shown that it’s safe to become pregnant after bariatric surgery, but the pregnancies are accompanied by other risks. For example, there is a higher risk of small for gestational age (SGA) babies, but the mothers have a lower risk of developing gestational diabetes mellitus (GDM). Until now the women get tested for GDM through divers protocols, but there are no adapted diagnostic methods or adapted cut-off values.
Method: Our study consists of a literature review and a retrospective cohort study where we looked at the pregnancy outcomes of 69 pregnancies of women who previously had bariatric surgery.
Results: There is no consensus when it comes to glucose cut-off values and screening methods for GDM for women who have had bariatric surgery. Our cohort study shows that the prevalence of SGA babies is higher (25%) than in the normal population. 5.8% of our population had insulin-treated GDM and 24% had GDM for which they had a diet.
Conclusion: We can conclude that more research must be done about screening methods for GDM for women who have had bariatric surgery. Compared to the normal population, our study shows a higher prevalence of SGA babies and a lower prevalence of large for gestational age babies. We couldn’t identify variables which showed a significant relation.
