GDM Flashcards
What is the A1c and BG goal for pre-existing diabetes during pregnancy?
A1c <6%
Pre-meal/fasting glucose: 60 to 99 mg/dL
peak postprandial: <129 mg/dL
Why is planed pregnancy important?
Fetal organ formation takes place in first 8 weeks and uncontrolled glucose may result in spontaneous abortion or congenital abnormalities (neural tubal, heart, kidneys)
What happens at 18 weeks gestation when the placenta is fully grown and functioning?
The fetus can now develop metabolic complications secondary to the maternal hyperglycemia
What us the most common complication of the 2nd and 3rd trimester - maternal hyperglycemia?
neonatal hypoglycemia
What is the maternal complication of uncontrolled glucose?
Preeclampsia (hypertension), preterm labor and delivery, c-section, pyelonephritis
What is the target blood pressure in GDM?
How is B/P treated in GDM?
110/65 - 129-79
Calcium channel blocker and labetalol. ACE and ARBS are contraindicated
What is the screening for GDM?
Screen all women at 1st prenatal visit
Test between 24-28 weeks for those with average risk
Use 75 gram OGTT
When is GDM diagnosed?
Fasting >95 mg/dL
1 hour post OGTT >180 mg/dL
2 hours post OGTT >150mg/dL
Daily carb allowance for pregnant women and non-pregnant women?
Pregnant: 175 grams/day over 3 small-moderate meals and
2-4 snacks
Non-pregnant: 130 grams per day
Insulin requirements during pregnancy
Insulin resistance tends to increase during GDM.
Insulin requirements increase in late gestation and generally do not decline until after delivery
BG targets for pregnant women
Targets are the same for women with/out DM
Fasting & premeals <95
1 hour post-prandial <140
2 hour post-prandial <120
Nutritional goals for gestational diabetes
Maintain euglycemia while consuming enough calories and carbs to promote appropriate weight gain and avoid maternal starvation ketosis
Calorie restriction for GDEM with BMI >30
30 -33% calorie restriction. Approximately 25 cal/kg ob body wit. This has shown
As pregnancy progresses, what happens to insulin needs
Insulin needs increase d/t wt gain and increased placental hormones especially during the last trimester
Placenta hormones help baby grow at the same time these hormones block the action of the mother’s insulin resulting in increased insulin needs.
Pregnancy weight goals
Underweight 28-40 lbs
Normal 25-35
Overweight 15-25
Obese 11-20
