Screening for Gestational Diabetes
Experts debate whether all pregnant women need to be tested for gestational diabetes.
But the American Diabetes Association recommends that doctors screen women:2
- At the first prenatal visit if they are at risk for having type 2 diabetes.
- Between the 24th and 28th weeks of pregnancy if they are not already diagnosed with diabetes using the oral glucose tolerance test.
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 diabetes before you become pregnant and also early in your pregnancy.
