In: Rifai N, ed. Editorial team. Glucose tolerance test - non-pregnant. How the Test is Performed. The most common glucose tolerance test is the oral glucose tolerance test OGTT. Before the test begins, a sample of blood will be taken. The OGTT is done when you're between 24 and 28 weeks pregnant. If you've had gestational diabetes before, you'll be offered an OGTT earlier in your pregnancy, soon after your booking appointment, then another OGTT at 24 to 28 weeks if the first test is normal.

If you have gestational diabetes, the chances of having problems with your pregnancy can be reduced by controlling your blood sugar levels. Blood sugar levels may be reduced by changing your diet and exercise routine. However, if these changes don't lower your blood sugar levels enough, you will need to take medicine as well. This may be tablets or insulin injections.

You'll also be more closely monitored during your pregnancy and birth to check for any potential problems. If you have gestational diabetes, it's best to give birth before 41 weeks. Induction of labour or a caesarean section may be recommended if labour does not start naturally by this time.

Earlier delivery may be recommended if there are concerns about your or your baby's health or if your blood sugar levels have not been well controlled.

Then, your provider may test you again after you have changed your diet.

If more than one of your blood glucose results is higher than normal, you have gestational diabetes. You may have some of the symptoms listed above under the heading titled "How the Test will Feel.
