A pregnancy with gestational diabetes can also increase the risk of preeclampsia, Cesarean birth, and large for gestational age infants.

Alternatives to the test

During pregnancy, there are some alternatives to the oral glucose tolerance test. These tests can help you find out if you are at risk for gestational diabetes.

If you are at risk for diabetes, you may be offered this test at a routine prenatal visit. In this test, a blood sample is drawn, then the level of blood insulin is measured.

Having this test earlier is recommended for women who have high blood glucose levels in their urine during routine prenatal visits.

Alternatives to the oral glucose test drink are also available. A jelly bean test is a popular alternative. This test is much less invasive than the oral glucose test drink, with fewer side effects. To perform the test, you will need to consume 28 jelly beans, which will provide you with 50 grams of sugar.

Jelly beans are also available in naturally colored brands. You can also purchase GMO-free jelly beans. Using jelly beans is more appealing than drinking a drink, and you can make them equal with a meal.

Another alternative is the at-home glucose test. At-home testing can help you learn more about your body and your energy levels. You will need to conduct at least three tests a day.
