In the last decade, it has become clear that gestational diabetes is a
clinical entity associated with perinatal mortality and morbidity. Th
us, the attention to and management sf gestational diabetes during pre
gnancy are mandatory. In this review, results of 58 original studies (
spanning the past 20 years) addressing criteria for insulin management
in gestational diabetes were assessed. The level of glycemic control
and its evaluation through self-monitoring of blood glucose are the fo
undation for ascertaining optimal pregnancy outcome. This review addre
sses the criteria for insulin initiation: insulin requirements, identi
fication of the right patient, the timing for insulin initiation, and
the behavioral adjustment and compliance during insulin therapy It is
recommended that patients with fasting plasma glucose on the oral gluc
ose tolerance test (OGTT) of <96 mg/dl land ideally nonobese) be assig
ned to diet therapy Obese women or those with fasting plasma glucose >
95 mg/dl on the OGTT should be referred to insulin therapy in order to
minimize exposure of the fetus to a hyperglycemic environment.
