G is for Gestational Diabetes

Gestational diabetes develops during pregnancy (gestation). Like other types of diabetes, gestational diabetes affects how your cells use sugar (glucose). Gestational diabetes causes high blood sugar that can affect your pregnancy and your baby's health.

Any pregnancy complication is concerning, but there's good news. Expectant women can help control gestational diabetes by eating healthy foods, exercising and, if necessary, taking medication. Controlling blood sugar can prevent a difficult birth and keep you and your baby healthy.

In gestational diabetes, blood sugar usually returns to normal soon after delivery. But if you've had gestational diabetes, you're at risk for type 2 diabetes. You'll continue working with your health care team to monitor and manage your blood sugar.

Glucose screening tests during pregnancy

A glucose screening test is a routine test during pregnancy that checks a pregnant woman's blood glucose (sugar) level.

Gestational diabetes is high blood sugar (diabetes) that starts or is found during pregnancy.

TWO-STEP TESTING

During the first step, you will have a glucose screening test:

  • You DO NOT need to prepare or change your diet in any way.
  • You will be asked to drink a liquid that contains glucose.
  • Your blood will be drawn 1 hour after you drink the glucose solution to check your blood glucose level.

If your blood glucose from the first step is too high, you will need to come back for a 3-hour glucose tolerance test. For this test:

  • DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.)
  • You will be asked to drink a liquid that contains glucose, 100 grams (g) .
  • You will have blood drawn before you drink the liquid, and again 3 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked.
  • Allow at least 3 hours for this test.

ONE-STEP TESTING

You need to go to the lab one time for a 2-hour glucose tolerance test. For this test:

  • DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.)
  • You will be asked to drink a liquid that contains glucose (75 g).
  • You will have blood drawn before you drink the liquid, and again 2 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked.
  • Allow at least 2 hours for this test.
