What to Expect from a Gestational Diabetes Test

All women are tested for gestational diabetes during their pregnancy. Even if you’ve had no prior issues with blood sugar levels in your day-to-day life or previous pregnancies, you will still be tested if you’re a surrogate with Growing Generations.

While being a surrogate does not raise the odds of developing gestational diabetes, there are certain elements of a surrogate pregnancy that may contribute to more significant insulin resistance and the development of gestational diabetes.

According to the Mayo Clinic, the risk for developing gestational diabetes rises with the following factors:

  • Increasing maternal age, starting in women more than 25 years of age
  • Carrying multiples
  • Excessive weight
  • Non-Caucasian race

Since multiple pregnancies are more common when using IVF, and most surrogates tend to be over the age of 25, you naturally carry a few extra risk factors than you may have had in your personal pregnancies. As a result, your glucose tolerance test may show elevated glucose levels.

All About Testing

Gestational diabetes testing is typically done around the 24th week of pregnancy. It includes a non-fasting laboratory test, where you will be asked to consume 8 ounces of a highly sugared glucose drink. In some cases, you may be asked to consume the beverage at home before coming in. You will remain at the lab for one hour before having your blood drawn. Technicians will analyze that sample to review your glucose levels.

If the one-hour glucose tolerance test comes back elevated, this does not automatically mean that you have or will be diagnosed with diabetes. Instead, you will be asked to take a three-hour version of the test.

You will be asked to fast for a period of 12 hours before the three-hour test. When you show up at the lab, you’ll give a baseline blood draw before consuming the sugared glucose drink. Your blood will be drawn again at one hour, two hours and three hours. Doctors will look to see if your body is able to self-regulate and lower glucose levels within a certain time frame. If your levels are elevated and you are not able to regulate without intervention, you will be diagnosed as a gestational diabetic.

Now What?

If you are diagnosed, it is important to understand that there is nothing you could have done to prevent this. It’s not a lifestyle issue, so you shouldn’t feel guilty or ashamed. Unlike type 1 diabetes, which is typically inherited, and type 2 diabetes, which typically is the result of excessive weight and poor diet, gestational diabetes tends to be linked to how the body regulates pregnancy hormones.

In most cases, gestational diabetes can be managed by closely monitoring your diet and adding a bit of additional exercise. You will be asked to monitor your glucose levels with a home testing kit and keep a strict log of your food intake and sugar levels. You likely won’t have to change much about your lifestyle.

If you simply are unable to control your blood sugar levels, even with strict adherence to diet and exercise, you may be asked to take oral medication or inject insulin to keep your body’s chemistry in check.

For most women, gestational diabetes will go away once the child is born. The American Diabetes Association says women who developed gestational diabetes should have a two-hour glucose tolerance test at six weeks postpartum to ensure that the diabetes has cleared up. Women who have developed gestational diabetes will be at an increased risk of developing type 2 diabetes later in life and should plan to have sugar levels tested every three years following their delivery.
