Screening for Gestational Diabetes - Topic Overview

Early detection

The U.S. Preventive Services Task Force and American Diabetes Association recommend that all women who are not already diagnosed with diabetes be screened for gestational diabetes after the 24th week of pregnancy.12 Most women are screened for gestational diabetes between the 24th and 28th weeks of pregnancy.

After delivery

Even though your gestational diabetes will probably go away after your baby is born, you are at risk for gestational diabetes again and for type 2 diabetes later in life. Up to 60 out of 100 women who develop gestational diabetes will develop type 2 diabetes later in life.3

You may also have a follow-up glucose tolerance test 6 to 12 weeks after your baby is born or after you stop breast-feeding your baby. If the results of this test are normal, you will still need to be tested for type 2 diabetes at least every 3 years. If that test shows that your blood sugar is slightly high, you may have a condition called prediabetes. If you have prediabetes, you can help prevent type 2 diabetes by changing the way you eat, exercising regularly, and being tested for diabetes every year. For more information, see the topic Prediabetes.

If you want to get pregnant again, you should be tested for type 2 diabetes before you become pregnant.

    If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

    People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

    Congratulations on taking steps to manage your health.

    However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

    Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

    Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

    One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
