Screening for Gestational Diabetes

Screening for Gestational Diabetes

Topic Overview

Early detection

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.footnote 1footnote 2 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.

You may also have a follow-up glucose tolerance test 4 to 12 weeks after your
baby is born or after you stop breastfeeding your baby. If the results of this
test are normal, you will still need to be tested
for type 2 diabetes
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

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