Continuous Glucose Monitoring
Î 3.3. ES suggests that continuous glucose monitoring be used during
pregnancy in women with overt or gestational diabetes when self-
monitored blood glucose levels (or, in the case of the woman with overt
diabetes, HbA1c values) are not sufficient to assess glycemic control
(including both hyperglycemia and hypoglycemia). (2|⊕⊕

Table 3. Preconception Glycemic Targets for Women With
Overt Diabetes and During Pregnancy for Women
With Either Overt Diabetes or Gestational Diabetes
a
Target Value, mg/dL (mmol/L)
Preprandial blood glucose ≤95 (5.3)
b
1 h aer the start of a meal ≤140 (7.8)
2 h aer the start of a meal ≤120 (6.7)
a
Note that blood glucose meters use capillary blood but display corrected results equivalent to plasma
glucose levels.
b
Target fasting blood glucose is ≤90 (5.0 mmol/L) if this can be safely achieved without undue
hypoglycemia.
