Pregnancy in formerly type 2 diabetes obese women following biliopancreatic diversion for obesity.

Background: This study describes the pregnancy of previously obese women with type 2 diabetic who reduced body weight and normalized serum glucose level following biliopancreatic diversion (BPD) for obesity.
Methods: A subset of ten women who had type 2 diabetes prior to BPD and who developed pregnancy after the operation was retrospectively identified.
Results: All pregnancies were completely normal, and serum glucose levels remained within the physiological range throughout all the pregnancy. These post-diabetic women delivered 13 infants in good health with a normal birth weight and no case of macrosomia.
Conclusions: These data are a clinical confirmation of the post-BPD improvement of beta-cell response to increased functional demand in obese patients with preoperative type 2 diabetes.
