When should I get checked for gestational diabetes during pregnancy?

Ms. Vandana  R. Sheth
Nutrition & Dietetics Specialist
Depending upon your risk level, you might get checked at your first prenatal visit or later.  If you are at high risk (over weight, family history of diabetes, history of previous pregnancy with gestational diabetes, you might be tested at your first prenatal visit.  Typically, most women are screened for gestational diabetes in the 2nd trimester (~24-28 weeks of pregnancy).

Your doctor will decide when you need to be checked for diabetes during your pregnancy, depending on your risk factors.

If you are at high risk, your blood glucose level may be checked at your first prenatal visit. If your test results are normal, you will be checked again sometime between weeks 24 and 28 of your pregnancy. If you have an average risk for gestational diabetes, you will be tested sometime between weeks 24 and 28 of pregnancy. If you are at low risk, your doctor may decide that you do not need to be checked.

This answer is based on source information from the National Institute of Diabetes and Digestive and Kidney Diseases.

It is recommended that all pregnant women, regardless of risk, be screened for gestational diabetes mellitus (GDM) between 24 and 28 weeks’ gestation. Women with specific risk factors or who develop signs or symptoms consistent with GDM will be screened earlier in the pregnancy.

When you first seek out prenatal care, the nurse midwife or physician will usually draw prenatal lab work. If your blood sugar happens to be elevated above the normal range at this time, your healthcare provider may request that you come back for additional lab work to be done. Usually, gestational diabetes is not tested for until about 28 weeks of pregancy. Your healthcare provider will have you do an oral glucose tolerance test where you have your fasting blood sugar drawn, then you drink a high glucose drink and have your blood sugar redrawn at intervals after. Any elevations or abnormals can be detected at this time.
