During pregnancy — usually around the 24th week — some women develop gestational diabetes. Based on recently announced diagnostic criteria for gestational diabetes, the American Diabetes Association estimates that it affects about 18% of pregnancies in the U.S.
As part of your routine prenatal care, your blood glucose level will be tested. If you have gestational diabetes, you will work with your doctor to control your blood sugar levels.
A diagnosis of gestational diabetes doesn’t mean that you had diabetes before you conceived, or that you will have diabetes after giving birth. But it’s important to follow your doctor’s advice regarding blood glucose (blood sugar) levels throughout your pregnancy, so you and your baby both remain healthy.
