Women with GDM in multiple tourncies should be-monitor blood glucose levels at least four times daily (fasting and on e hour post prandial). Fasting pretends ≤ 95 mg / dL and one-hour postprandial ≤ 140 mg / dL are typical, though some clinicicians use herter proxy (≤ 90 mg / dL fasting) given thee pregeleed risk of macrosomia.

Antenatal visits every 1- 2 weeks are standard, with more frequent fetal gesticulance (nonstres tests or biophysical profiles) startin at 32- 34 weeks.
