7% of all U.S. pregnancies, or about 200,000 cases annually
Increased lifelong risk for mother and child for developing type 2 diabetes
Note:
Gestational diabetes mellitus is a form of glucose intolerance diagnosed in some women during pregnancy.
Gestational diabetes affects 7%, or about 200,000 U.S. pregnancies each year.
After pregnancy, 5% to 10% of women with gestational diabetes are found to have type 2 diabetes. Women who have had gestational diabetes have an increased lifelong risk—up to a 50% chance—of developing diabetes in the next 5 to 10 years after pregnancy. Their offspring are also at higher risk for obesity and type 2 diabetes compared to other children.
Gestational diabetes is more common among African Americans, Hispanic/Latino Americans, and American Indians and Alaska Natives. It is also more common among obese women and women with a family history of diabetes.
