ATLANTIC DIP: Despite insulin therapy in women with IADPSG diagnosed GDM, desired pregnancy outcomes are still not achieved. What are we missing?

GDM-I and GDM-M mothers have similar rates of maternal medical morbidities. Despite this, the rate of delivery by CS remains greater, possibly driven by physician choice for elective intervention in the GDM-I group. Despite insulin therapy, offspring of GDM-I mothers experience higher rates of macrosomia, LGA and NICU admissions. This may be related to the higher baseline risk profile in GDM-I women, to sub-optimal glycaemic control, excessive gestational weight gain (GWG) or higher baseline BMI of the mother. Addressing baseline maternal BMI, limiting excessive GWG and tightening glycaemic control in GDM-I women may translate to better pregnancy outcomes.
