Pregnancy causes many changes in the body. Some changes may affect how the body handles sugar in the blood. When this happens, gestational diabetes (GDM) can develop.
GDM starts during pregnancy. It happens when the body cannot make enough insulin. Insulin helps keep blood sugar at a healthy level.
A GDM diagnosis can feel scary. But many women with GDM have healthy pregnancies. With the right care and support, both mom and baby can stay healthy.
You will be tested for this diabetes between 24 and 28 weeks of pregnancy. Some people may be tested earlier if they have a higher risk. You can be at a higher risk for GDM if you:
- Are overweight or obese
- Had GDM during a previous pregnancy or
- Have given birth to a baby weighing more than 9 pounds
- Have a family history of type 2 diabetes
- Are a Black, Hispanic, American Indian, Asian American, Alaska Native, Native Hawaiian or Pacific Islander person
- Have polycystic ovary syndrome (PCOS)
Testing helps with early detection. When problems are found early, care can begin sooner.
Keeping blood sugar at a healthy level can help lower the chance of problems during pregnancy, such as:
- High blood pressure during pregnancy
- Having a very large baby
- Problems during delivery
- Cesarean birth
- Low blood sugar in newborns
With the right care, these risks can often be reduced. Healthy habits and regular monitoring are key. Treatment may include:
- Healthy eating to help keep blood sugar levels steady
- Gentle exercise
- Checking blood sugar levels regularly
- Medication, such as insulin, if needed
A Continuous Glucose Monitor (CGM) can track blood sugar during the day. This helps show patterns. It can also alert you when levels are too high or too low. A dietitian can guide food choices with nutrition counseling. They can also help with meal timing and portion sizes. Your OB-GYN can provide a referral for you. Virtual nutrition counseling is also available through your plan at Maven.
Support is available when you need it. As a member of Aetna Better Health® of Illinois, helpful tools and resources are available through your health plan. CGMs are covered for eligible members. These monitors can make GDM easier to manage.
Care Managers can also help members stay on track with care and resources. They can also help if you are having a hard time accessing healthy food or transportation to your doctor’s appointments. Call Member Services at 1-866-329-4701 (TTY: 711) to learn more.
Care is still important after your baby is born. Postpartum care helps protect long-term health. After delivery, blood sugar often returns to normal. However, testing 4 to 12 weeks after birth and every 1 to 3 years after that is recommended because the risk of type 2 diabetes remains higher after GDM. Regular checkups can help catch changes early.
With the right care, tools and support, small steps during pregnancy can help support a healthy pregnancy and a healthy future for both parent and baby.
