What is gestational diabetes?

Gestational diabetes (pronounced jess-tay-shun-ul die-uh-beet-eez) is a type of diabetes, or high blood sugar, that only pregnant women get. In fact, the word gestational means pregnant. If a woman gets high blood sugar when she's pregnant, but she never had high blood sugar before, she has gestational diabetes. Nearly 135,000 pregnant women get the condition every year, making it one of the top health concerns related to pregnancy.

If not treated, gestational diabetes can cause problems for mothers and babies. Some of these problems can be serious.

But there is some good news:

• Most of the time, gestational diabetes goes away after the baby is born. The changes in your body that cause gestational diabetes normally occur only when you are pregnant. After the baby is born, your body goes back to normal and the condition goes away.

• Gestational diabetes is treatable, especially if you find out about it early in your pregnancy. The best way to control gestational diabetes is to find out you have it early and start treatment quickly.

• Treating gestational diabetes greatly lowers the baby's chances of having problems.

Why do some women get gestational diabetes?

Usually, the body breaks down much of the food you eat into a type of sugar, called glucose (pronounced gloo-kos). Because glucose moves from the stomach into the blood, some people use the term blood sugar, instead of glucose. Your body makes a hormone called insulin (pronounced in-suh-lin) that moves glucose out of the blood and into the cells of the body. In women with gestational diabetes, the glucose can't get into the cells, so the amount of glucose in the blood gets higher and higher. This is called high blood sugar or diabetes.

How do I know if I'm at risk?

Should I get tested?

Keep in mind that every pregnancy is different. Even if you didn't have gestational diabetes when you were pregnant before, you might get it during your current pregnancy. Or, if you had gestational diabetes before, you may not get it with this pregnancy. Follow your doctor's or nurse's advice about your risk level and getting tested.

What is involved in getting tested?

Tests for gestational diabetes have two parts. First, you drink about one full glass of a sugar drink. Then, after a certain amount of time, a doctor, nurse, or other healthcare worker takes a sample of your blood and tests the blood to see how much sugar is in it (called a blood sugar test).

If the level of sugar in your blood is normal, then you probably don't have gestational diabetes.

If your blood sugar level is high, then you might have gestational diabetes. Your doctor or nurse may want you to take another blood test if your blood sugar level is high. Your doctor or nurse will tell you more about the test before you take it.

You may have to follow a special diet for a few days or fast (not eat or drink anything but water) for a few hours before you take the test. Ask your doctor or nurse if you have to follow any special instructions before you get tested.

What if I don't get treated for gestational diabetes?

Most women with gestational diabetes have healthy pregnancies and healthy babies because they control their condition. Without treatment, mothers with this condition could have very large babies. These mothers may have a harder time with labor and natural delivery (through the vagina). Some mothers need surgery to deliver their bigger babies, which can increase the mother's risk of infection. Mothers who have their babies by surgery also take a longer time to recover.

Children whose mothers had gestational diabetes are at higher risk for certain health problems:

• As babies, they are at higher risk for Respiratory Distress Syndrome (RDS), a disease that makes it hard for the baby to breathe.

• They are more likely to be obese (very overweight) as children or adults, which can lead to other health problems.

• They are at higher risk for getting diabetes, or high blood sugar, as they get older.

What should I do if I have gestational diabetes?

If your doctor or nurse tells you that you have gestational diabetes, you will need to follow a treatment plan to keep the condition under control. Most treatment plans include testing your blood sugar level, eating a healthy diet, and getting regular physical activity. Some women also need to take insulin as part of their treatment plan.

Managing Gestational Diabetes: Your Guide to a Healthy Pregnancy, a booklet from the National Institute of Child Health and Human Development (NICHD), talks about general ways to stay healthy with gestational diabetes. The booklet combines advice from experts who treat gestational diabetes with nearly 40 years of scientific research on the health of mothers, children, and families. It tells you and your family what causes gestational diabetes, what having it means for you and your baby, and what you can do if you have it.

You can learn more about gestational diabetes and how to stay healthy during your pregnancy from the NICHD booklet, Understanding Gestational Diabetes: A Practical Guide to a Healthy Pregnancy. To get your free copy of the booklet, contact the NICHD Clearinghouse at:
