A simple blood-sugar
test can tell.For most women, gestational diabetes goes away once their baby is born. However, more than half of the women who have gestational diabetes will get it again with future pregnancies and may get type 2 diabetes later in life.
Many doctors give pregnant women a blood test at about 24 to 28 weeks of pregnancy to test for gestational diabetes. Women who have a high risk of getting gestational diabetes (those who had gestational diabetes with an earlier pregnancy) may be tested before the 24th week. The blood-sugar test is simple: You are asked to drink “sugar water” and an hour later a sample of your blood is drawn and your glucose level is measured. If the glucose level in your blood is within the normal range (120 mg/dl –– milligrams of glucose per deciliter of blood ), no other tests are needed. However, if your blood glucose level is within the normal range, but you are at high risk for gestational diabetes, you may be tested again later in your pregnancy. If your blood-glucose level is above the normal range, you will be asked to take a second test called a glucose tolerance test to be certain whether or not you have gestational diabetes.
