Gestational Diabetes Nutrition Guide: Managing Blood Sugar for You and Baby
Understanding Gestational Diabetes
Gestational diabetes mellitus (GDM) develops when your body can’t produce enough insulin to handle the demands of pregnancy, resulting in high blood sugar levels. This typically occurs around 24-28 weeks and affects about 2-10% of pregnancies.
What’s Happening in Your Body?
✔ Insulin resistance – Pregnancy hormones block insulin’s effectiveness
✔ Pancreas struggles to produce 2-3x more insulin needed
✔ Excess glucose crosses placenta, causing baby to grow larger
✔ Increased risk of preeclampsia and future Type 2 diabetes
The good news? With proper diet and monitoring, most women control GDM effectively!
Best Foods for Gestational Diabetes
Carbohydrates (30-45g per meal)
Why? The right carbs prevent spikes while fueling baby’s growth
✔ Non-starchy veggies – Broccoli, spinach, peppers (5g carbs/cup)
✔ High-fiber grains – Quinoa, oats, whole wheat bread (15g/serving)
✔ Low-glycemic fruits – Berries, apples, pears (15g/serving)
Protein (20-30g per meal)
Why? Stabilizes blood sugar and supports baby’s development
✔ Lean meats – Chicken, turkey, lean beef
✔ Fish – Salmon, sardines (2-3x/week for omega-3s)
✔ Plant proteins – Lentils, tofu, Greek yogurt
Healthy Fats (10-15g per meal)
Why? Slows carb absorption and reduces inflammation
✔ Avocados
✔ Nuts & seeds – Almonds, chia seeds
✔ Olive oil

✔ Space meals every 2-3 hours (3 meals + 3 snacks)
When to Call Your Doctor
Consistently high readings (fasting >95, 1hr post-meal >140)
Ketones in urine (may indicate need for insulin)
Excessive thirst/frequent urination
Blurred vision or extreme fatigue
