Gestational Diabetes (GD)


Updated January 25, 2014

Written or reviewed by a board-certified physician. See About.com's Medical Review Board.

Definition: When a pregnant woman has high blood sugar levels in pregnancy. About 4% of pregnancies are affected by gestational diabetes, not to be confused with a pregnant diabetic. This is screened for in your prenatal visits, typically around the 28th week of pregnancy with a test called the glucose tolerance test (GTT). If the numbers of this test are high, you will be asked to do a three hour version of the test t confirm the diagnosis.

Being diagnosed with gestational diabetes means that you will need to check your blood sugars multiple times a day. Typically this is managed in pregnancy with nutrition and exercise, though medications and insulin may be needed for some women.
