Screening for gestational diabetes is a way to look for high blood sugar during pregnancy. You drink some very sweet liquid. Then you have a blood test to see how your body uses sugar (glucose).
Screening for gestational diabetes may be done in a couple of ways.
Sometimes doctors use the OGTT on its own. If the test shows that you don't have a lot of sugar in your blood, you don't have gestational diabetes. If you do have a lot of sugar in your blood, you may have the condition.
Your blood glucose level may drop very low toward the end of the test. If this happens, you may feel weak, hungry, and restless. Tell your doctor if you have these symptoms. The test usually will be stopped.
You may vomit after drinking the sweet liquid. If this happens, you may need to take the test at a later time.
Your doctor may do more glucose tests at other times during your pregnancy.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
