Evidence indicates that mean blood glucose between
87-104 mg/dL is associated with the lowest incidence of either
large or small for gestational age deliveries.42 Another study
demonstrated that 1hr. postprandial blood glucose levels of 130
mg/dL had a similarly low risk of large or small for gestational
age deliveries.43 Evidences suggests the superiority of daily selfmonitoring
of blood glucose (SMBG) to intermittent clinic-based
monitoring of plasma glucose.44,45 It has been suggested that
better outcomes are seen when SMBG is performed 4-6 times
daily.46 Unlike non-pregnant patients with diabetes, in GDM
postprandial monitoring of blood glucose after 60 minutes has
been shown to be associated with better outcomes. It has been
shown that maternal peak plasma glucose levels are seen 90
minutes postprandially.47 In women with GDM postprandial
glucose monitoring is associated with significantly lower levels of
macrosomia, neonatal hypoglycaemia and caesarean deliveries
due to shoulder dystocia.48 Postprandial hyperglycaemia must
be reduced, as several studies have shown.49
