Gestational Diabetes in the U.S.: Key Facts
- Affects 6-9% of pregnancies (~300,000 cases annually)
- Risks if uncontrolled:
- Mother: 50% higher C-section risk, future type 2 diabetes (7x risk)
- Baby: Macrosomia (9-12 lbs), neonatal hypoglycemia, NICU admission
Good News: With proper care, 90% of cases can be managed without medication!
5-Point GDM Management Plan
1. Glucose Monitoring (Covered by most U.S. insurers)
- Targets:
- Fasting: <95 mg/dL
- 1hr post-meal: <140 mg/dL
- 2hr post-meal: <120 mg/dL
- Testing Schedule:
- Newly diagnosed: 7x/day (pre/post meals + bedtime)
- Stable: 5x/day (fasting + post-meals)
- Pro Tip: Peak glucose occurs 45-70 mins post-meal—time walks accordingly!

2. Exercise Prescription
- Best Choices:
- Walking (20 mins post-meal → drops glucose 20-40 mg/dL)
- Swimming, prenatal yoga
- Avoid: Contact sports, hot yoga
- Safety: Stop if you experience contractions, dizziness, or vaginal bleeding.
3. Diet Strategies (ADA-Recommended)
- Plate Method:
- ½ non-starchy veggies
- ¼ lean protein
- ¼ whole grains
- Carbs: 175g/day minimum (focus on low-GI choices)
- Snack Hack: Move fruit between meals to prevent spikes.
4. Medication Options
- First-line: Insulin (doesn’t cross placenta)
- Rapid-acting: Pre-meals
- Long-acting: Bedtime
- 2nd-line: Metformin (crosses placenta; limited long-term safety data)
5. Postpartum Care
- 6-12 weeks postpartum: Take a 75g OGTT
- Lifelong:
- Annual glucose checks (50% develop T2D within 10 years)
- Breastfeeding cuts diabetes risk by 15-30%
