Gestational Diabetes Risk Factors

Posted: Nov. 1, 2004

Gestational diabetes 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.

What is gestational diabetes?
Usually, the body breaks down much of the food you eat into a type of sugar, called glucose. 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 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?
Answer the questions below to determine your risk level for gestational diabetes.

1. Are you a member of a high-risk ethnic group (African Americans, Hispanic/Latino Americans, American Indians, indigenous Australians, South or East Asian, Pacific Islander, or Indigenous Australian)?
2. Are you overweight or very overweight?
3. Are you related to anyone who has diabetes now or had diabetes in his or her lifetime?
4. Are you older than 25?
5. Did you have gestational diabetes with a past pregnancy?
6. Have you had a stillbirth or a very large baby with a past pregnancy?

If you answered YES to TWO or more of these questions, you are at HIGH RISK for gestational diabetes.

If you answered YES to ONLY ONE of these questions, you are at AVERAGE RISK for gestational diabetes.

If you answered NO to ALL of these questions, you are at LOW RISK 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.
