Pregestational diabetes mellitus: Obstetrical issues and management

Vanessa A Barss, MD, FACOG


The key elements in management of pregnancies complicated by diabetes are:

Achieving and maintaining excellent glycemic control

Screening, monitoring, and intervention for maternal medical complications (eg, retinopathy, nephropathy, hypertension, cardiovascular disease, ketoacidosis, thyroid disease)

Monitoring of, and intervention for, fetal and obstetrical complications (eg, congenital anomalies, preeclampsia, macrosomia)

Most issues related to the obstetrical management of a pregnant diabetic woman (type 1 or type 2) will be reviewed here. The obstetrical management of these pregnancies is largely based upon clinical experience, data from observational studies, and expert opinion [1,2]. There is virtually no evidence from randomized trials.
