How to Detect and Manage Gestational Diabetes Early
Gestational diabetes affects up to 10% of pregnancies, often without obvious symptoms. That’s why it’s crucial to detect and manage gestational diabetes as early as possible — to protect both you and your baby. In this post, we cover the early warning signs, testing timeline, and safe blood sugar control strategies.
What Is Gestational Diabetes?
Gestational diabetes mellitus (GDM) is a condition where your body can’t produce enough insulin during pregnancy. This leads to high blood sugar, which can cause complications like preeclampsia, preterm birth, and even type 2 diabetes later in life. According to the CDC, early detection is key to managing risk.
How to Detect Gestational Diabetes
Most women are screened between 24 and 28 weeks, but if you’re at high risk, your doctor may test you sooner. Detecting gestational diabetes early involves the following steps:
- Risk Assessment: Your OB-GYN will consider factors like BMI, age, family history, and ethnicity. Learn about pregnancy risk factors.
- Glucose Challenge Test (GCT): A one-hour test where you drink a sugary liquid and have blood drawn.
- Glucose Tolerance Test (OGTT): If your GCT result is high, this three-hour test confirms the diagnosis.
Early Symptoms to Watch For
While many experience no symptoms, some signs of high blood sugar during pregnancy include:
- Extreme thirst
- Frequent urination
- Fatigue (beyond normal pregnancy fatigue)
- Blurred vision
See our guide on early warning signs during pregnancy for a full list.
How to Manage Gestational Diabetes During Pregnancy
If you’re diagnosed, don’t panic — it’s manageable. Here’s how to manage gestational diabetes safely and effectively:
1. Monitor Blood Sugar Levels
You’ll likely be asked to check your blood sugar 4–6 times a day. Your doctor will give you target levels. Use a glucometer or continuous glucose monitor (CGM).
2. Follow a Balanced Diet
A diabetes-friendly pregnancy diet focuses on:
- Complex carbs like whole grains and legumes
- High-fiber vegetables
- Lean proteins and healthy fats
- Limiting processed sugars and white flour
Check our sample gestational diabetes meal plan.
3. Stay Active
Regular movement helps lower blood sugar. Aim for 20–30 minutes of light exercise daily, such as:
- Walking after meals
- Prenatal yoga (see our trimester-specific yoga guide)
- Swimming or light aerobics
4. Medication If Needed
If diet and exercise don’t keep your blood sugar in range, your provider may prescribe insulin or oral medications. The goal is always tight control to avoid complications.
Potential Risks If Left Untreated
Uncontrolled gestational diabetes increases the risk of:
- Macrosomia (large baby)
- Cesarean delivery
- Stillbirth
- Neonatal hypoglycemia
That’s why early detection and management are critical. NICHD emphasizes personalized prenatal care to reduce these risks.
How Gestational Diabetes Affects Baby After Birth
With proper treatment, most babies are born healthy. However, babies born to mothers with GDM may be monitored for:
- Low blood sugar (hypoglycemia)
- Jaundice
- Breathing difficulties
- Higher risk of obesity and diabetes later in life

Final Thoughts: Detect and Manage Gestational Diabetes Early
To detect and manage gestational diabetes early is to stay empowered. With early screening, a solid care plan, and a few lifestyle adjustments, you can minimize risks and have a healthy pregnancy.
If you’re concerned about your risk or symptoms, speak to your provider and request early screening. Learn more in our pregnancy lab tests guide.
FAQ
Is gestational diabetes permanent?
No. It usually resolves after birth, but women who’ve had GDM have a 50% higher risk of developing type 2 diabetes later. Postpartum screening is essential.
Can I prevent gestational diabetes?
You can reduce your risk by maintaining a healthy weight, staying active, and eating a balanced diet. But sometimes it’s genetic and not preventable.
Does gestational diabetes mean my baby will have diabetes?
No, but it may increase your child’s future risk. Healthy habits during pregnancy and early childhood can offset this.
