How to Manage Gestational Diabetes During Pregnancy
Being diagnosed with gestational diabetes (GDM) during pregnancy can feel worrying, especially if it is your first experience with high blood sugar. The good news is that gestational diabetes is manageable, and with appropriate care, monitoring, and lifestyle changes, many women go on to have healthy pregnancies and healthy babies.
Gestational diabetes occurs when blood sugar levels become elevated during pregnancy. Pregnancy hormones can make the body more resistant to insulin, and sometimes the pancreas cannot produce enough insulin to keep blood sugar within the desired range. Importantly, gestational diabetes is not caused simply by something you ate, so there is no reason to blame yourself.
Why Is Managing Gestational Diabetes Important?
When blood sugar remains high, it can increase the risk of complications for both mother and baby. These can include excessive fetal growth, delivery complications, high blood pressure and preeclampsia, and problems with the baby’s blood sugar after birth.
Good blood sugar control can significantly reduce these risks and helps your healthcare team monitor your pregnancy more effectively.
1. Monitor Your Blood Sugar Regularly
One of the most important parts of managing gestational diabetes is checking your blood glucose as advised by your doctor.
You may be asked to check your blood sugar:
When you wake up, before eating
After meals
At other times recommended by your healthcare provider
Keep a record of your readings and share them during your prenatal appointments. Your doctor may adjust your treatment based on these results.
Common pregnancy glucose targets used by clinicians include a fasting level below 95 mg/dL, one-hour after eating below 140 mg/dL, and two-hours after eating below 120 mg/dL, although your personal targets may differ. Always follow the targets provided by your own healthcare team.
2. Follow a Balanced Meal Plan
Healthy eating is a cornerstone of gestational diabetes management.
Rather than simply avoiding all carbohydrates, focus on balanced meals with appropriate portions of carbohydrates, protein, vegetables, and healthy fats.
Your doctor or dietitian may recommend:
▸ Eating regular meals rather than skipping meals
▸ Choosing high-fiber foods such as vegetables, whole grains, and legumes
▸ Including protein with meals and snacks
▸ Limiting foods and drinks high in added sugar
▸ Choosing whole or minimally processed foods more often
▸ Following an individualized meal plan based on your nutritional needs
There is no single diet that works for every woman. A dietitian or diabetes educator can help create a meal plan that supports both your blood sugar control and your baby’s nutritional needs.
3. Stay Physically Active – If Your Doctor Says It Is Safe
Physical activity can help your body use glucose more effectively and can be an important part of managing blood sugar during pregnancy.
For women who have been cleared for exercise, activities such as walking, swimming, prenatal exercises, or other pregnancy-safe activities may be appropriate.
4. Take Medication When Necessary
Lifestyle changes are enough to control blood sugar for many women, but not everyone will reach their glucose targets through diet and activity alone.
If your blood sugar remains above your recommended range, your doctor may prescribe medication. Insulin is the preferred medication for treating hyperglycemia in gestational diabetes in current ADA guidance, and it is considered safe during pregnancy.
Needing insulin does not mean that you have failed to manage your diabetes. Pregnancy hormones can increase insulin resistance, and medication may simply be necessary to maintain healthy blood sugar levels.
Never start, stop, or change diabetes medication during pregnancy without speaking with your doctor.
5. Attend All Your Prenatal Appointments
Gestational diabetes may mean that you need more frequent prenatal visits.
Your healthcare team may monitor:
▸ Your blood glucose records
▸ Blood pressure
▸ Your weight and overall health
▸ Your baby’s growth
▸ Fetal well-being
▸ Other pregnancy-related risk factors
Additional ultrasound or fetal monitoring may be recommended depending on your individual circumstances.
Regular follow-up allows your healthcare team to identify problems early and adjust your treatment when necessary.
6. Know the Signs of Blood Sugar Problems
If you are monitoring your blood sugar, learn what your healthcare team considers too high or too low.
Low blood sugar can cause symptoms such as:
▸ Shakiness
▸ Sweating
▸ Dizziness
▸ Weakness
High blood sugar may also require medical attention, particularly when readings remain above your prescribed targets.
If you experience concerning symptoms or repeatedly get readings outside your recommended range, contact your healthcare provider rather than trying to adjust your treatment yourself.
7. Prepare for Delivery With Your Healthcare Team
Gestational diabetes does not automatically mean that you will need a cesarean delivery or an early delivery.
Your doctor will consider factors such as:
▸ Blood sugar control
▸ Baby’s growth
▸ Your overall health
▸ Blood pressure and other pregnancy complications
▸ How far along you are in pregnancy
The timing and method of delivery should be individualized based on your circumstances.
What Happens After Delivery?
For most women, gestational diabetes improves or resolves after the baby is born because the pregnancy-related hormonal changes that contribute to insulin resistance decrease. However, having gestational diabetes increases your future risk of developing type 2 diabetes.
That’s why postpartum follow-up is so important.
Can You Have a Healthy Pregnancy With Gestational Diabetes?
Yes. A diagnosis of gestational diabetes does not mean that you cannot have a healthy pregnancy or a healthy baby.
The key is to take the condition seriously and work closely with your healthcare team. Regular monitoring, nutritious food choices, appropriate physical activity, medication when necessary, and consistent prenatal care can help keep blood sugar under control.
Most importantly, don’t blame yourself. Gestational diabetes can happen because of the natural hormonal changes of pregnancy, and needing additional treatment is not a personal failure.
Gestational diabetes requires attention, but it doesn’t have to overshadow your pregnancy. With the right support and a personalized care plan, you can take practical steps to protect your health and your baby’s health.
If you have been diagnosed with gestational diabetes, speak with your obstetrician about your blood sugar targets, nutrition, exercise, monitoring schedule, and whether medication is needed. Do not make major dietary, exercise, or medication changes without medical guidance.
