Gestational
Diabetes[GDM] is present in two to three percent of all pregnancies
are complicated by and 15% of patients require insulin during pregnancy
[Class A2].
Diabetes
will often be diet controlled [Class A1] but up to 60% of patients with
GDM will become overtly diabetic 5-10 years postpartum. Thus, patients
should be screened at 6 weeks after delivery and yearly thereafter.
Diabetes Risk
Factors Include:
Obesity *
Positive family
history * [First degree relative]
History of glucose
intolerance *
History of a
macrosomic baby, stillbirth or congenital
anomaly
Hispanic, African
American, Native American or Pacific Islands ethnicity
Advanced maternal
age
* Patients with
these risk factors should be screened at the 1st prenatal visit and
later at 24-28 weeks
Pregestational
Diabetes
Less than 10% of
all women with diabetes in pregnancy have
pregestational diabetes. Less than 0.5% of women with diabetes in the
US receive preconception counseling and their infants are at significant
risk for
congenital anomalies.
Glycemic control
before and during pregnancy may reduce this risk. Patients using oral
hypoglycemics should switch to insulin preconception and ACE inhibitors
should be discontinued preconception.
