If the fetus is not macrosomic and the results of biophysical testing are reassuring, the obstetrician can await spontaneous labor. In patients with gestational diabetes mellitus and superb glycemic control, continued fetal testing and expectant management can be considered until 41 weeks' gestation. In the fetus with an abdominal circumference significantly larger than the head circumference or an estimated fetal weight above 4000 g, consider induction. After 40 or more weeks, the benefits of continued conservative management are likely to be outweighed by the danger of fetal compromise. Induction of labor before 41 weeks' gestation in pregnant women with diabetes, regardless of the readiness of the cervix, is prudent.
