You will need your blood drawn every hour for 2 to 3 hours for a doctor to diagnose gestational diabetes. High blood glucose levels at any two or more blood test times—fasting, 1 hour, 2 hours, or 3 hours—mean you have gestational diabetes.

Testing for gestational diabetes usually occurs between 24 and 28 weeks of pregnancy. How do doctors diagnose gestational diabetes? You will have your glucose tested before consuming a glucose drink and then tested again 1 and 2 hours later.

If your glucose is higher than specific cut-off values, it means you have GD. See the table for more specific information. If you are found to have GD, you will work closely with your health care provider s to keep your blood glucose levels in a healthy range. This involves choosing a healthy diet, gaining the recommended weight during your pregnancy, getting exercise, and if needed, taking insulin or pills to lower your blood sugar. If you have GD you will be offered a repeat glucose tolerance test between 6 weeks and 6 months postpartum to detect prediabetes and diabetes.

You may also be offered induction between weeks of pregnancy. Finally, it is strongly recommended that women with GD breastfeed their infants. We use cookies to improve functionality and performance. By clicking "OK" or by continuing to browse this site, you agree to the use of cookies.
