What is the target fasting blood glucose reading in gestational diabetes mellitus?

• A. <95 mg/dL
• B. <90 mg/dL
• C. <100 mg/dL
• D. <105 mg/dL

Answer: (A)

Aim for a fasting glucose under 95 mg/dL in gestational diabetes. This target, recommended by major guidelines, helps maintain overnight maternal glucose levels in a safe range and reduces fetal exposure to high glucose, which lowers the risk of fetal hyperinsulinemia and macrosomia, along with related complications. If fasting readings stay above 95 mg/dL, management starts with diet and activity adjustments, with escalation to insulin if needed. A lower target (around 90 mg/dL) risks maternal hypoglycemia without proven extra benefit, while higher targets (100–105 mg/dL) reflect less strict control and are not considered adequate for preventing adverse outcomes.
