If you may be at high risk for gestational diabetes , your healthcare provider may also consider certain aspects of your medical history.The provider may take into account your pre-pregnancy weight , your age, whether anyone in your family has had gestational diabetes or diabetes, your race or ethnic background , and outcomes of any previous pregnancies.Speak to your healthcare provider to find out whether you have a high risk or low risk of developing gestational diabetes. If the provider determines your risk is low, you may not have to take the glucose challenge test.

What Is A Glucose Screening Test

A glucose tolerance test, or glucose screening test, is usually done between 24 and 28 weeks of pregnancy. This is not a fasting test. You’ll be given a 50 gram glucose solution that must be drunk within five minutes it tastes a bit like syrupy flat soda. An hour after you’ve finished drinking the beverage, a blood sample is taken from a vein in your arm, and the glucose level is analyzed.

If the test result is abnormal, you’ll be given an additional confirmatory test called the three-hour glucose test. Unlike the first glucose tolerance test, which is for screening purposes, the three-hour test is a diagnostic tool for gestational diabetes.

How Do I Prepare For The Glucose Tolerance Test

Please read the information leaflet. Share the information it contains with your partner and family so that they can be of help and support. There may be information they need to know, especially if they are taking care of you following this examination.

Leading up to the test, please continue to eat your normal diet until the night before your test. Please do not restrict your sugar intake.

  • Mothers-to-be are given “Glucola,” which contains 50 grams of a sugar polymer. Their blood sugar level is measured 1 hour after drinking the drink.
  • Women who screen positive go on to the second step known as the Glucose Tolerance Test . This is either a 75 gram two hour test or a 100 gram three hour test. That same glucose drink is given but it can be in concentrations containing 50, 75 or 100 grams of sugar.
    • It can affect their digestive system leading to nausea, vomiting, bloating and diarrhea.

    Frankly, dont have diabetes.

    I know, that sounds heartless. But if you have diabetes, you NEED it to be found and be the safest for you and your baby.

    However, things I recommend:

    • Make sure youre eating a well-balanced diet the few days before the test. Have a mix of carbs and protein at each meal. Personally, Id stay away from sugar-filled snacks and drinks those few days.
    • You can always take a walk during the test that can help bring blood sugar down, but I dont think it will adjust it much either way.

    It is SO important you take the test. Your baby is at risk for stillbirth if you have diabetes and it is not taken care of.

    How To Prepare 3 Hour Test

    If your doctor would like to see additional testing, based on your results from the 1 hour test, you may be asked to have a 3 hour OGTT. It is important to follow all of the instructions very carefully, as it will affect the results of the test.

    When you arrive at the office a sample or baseline glucose test will be run and used for comparing other glucose values. You will be asked to drink a sweet liquid containing a measured amount of glucose, it is best to drink it quickly. Then blood samples will be collected at timed intervals of 1,2, and 3 hours after you drink the glucose.

    Here is the best method of preparation:

  • Eat a balanced diet that contains at least 150 grams of carbohydrates per day for 3 days before the test. Fruits, breads, cereal, rice, crackers, and starchy vegetables such as potatoes, beans and corn are good sources of carbohydrates.
  • Do not eat, drink, smoke, or exercise strenuously for at least 8 hours before your first blood sample is taken.
  • Tell your doctor about all prescription and nonprescription medicines you are taking. You may be instructed to stop taking certain medicines before the test.
  • The OGTT may take up to 4 hours. Since activity can interfere with test results, you will be asked to sit quietly during the entire test. Do not eat during the test. You may drink only water during this time.

    I hear that there are no risks associated with a glucose tolerance test.

    However, I have personally be affected by a VERY low blood sugar following the 3-hour test. Honestly, so low that I probably should have been in a coma.

    SO, I always recommend that on both the 1-hour and the 3-hour test that you bring something that has a nice balance of carbs and protein to eat right after the test is over. I usually take a peanut butter and honey sandwich since its easy to keep in my bag or my car. And can easily be eaten quickly.

    NOTE: This snack is for AFTER the test is over. Make sure you follow the instructions for the test during the procedure. It is really important.

    If you have any questions or concerns about the test, talk to your doctor or midwife. Theyll be happy to answer any questions you have.

    About Diabetes In Pregnancy

    Whenever we eat, a hormone called insulin helps move the sugar from our food through our blood and into our muscles, where it is turned into energy to help us move.

    When you are pregnant, your body produces lots of other hormones to help your baby grow. Some of these hormones can stop insulin working well. This causes sugar to build up in your blood because it cant get to your muscles. You have diabetes when you have too much sugar in your blood.

    Pregnancy diabetes generally goes away after your baby is born, though it leaves you with more chance of developing diabetes again later in life.

    Are There Any Side Effects Associated With The Glucose Tests

    Most pregnant women donât have any side effects during or after either glucose test. It’s possible that you may feel nauseous, lightheaded, or even sweaty after drinking the glucose solution. It tastes like a very sweet soda, which can be easier to stomach for some women than for others.Youâll need to have your blood drawn, so you might feel dizzy, and you may have slight bruising around the blood withdrawal spot, but otherwise the risks associated with these tests are minimal.

    How Does Gestational Diabetes Develop

    Your body makes a hormone called insulin to help keep your blood glucose at the right level. Your blood glucose levels become higher if your body doesnt make enough insulin or if your insulin does not work as well as it should.

    During pregnancy, hormones are made by the placenta to help the baby develop and grow. These hormones, however, can stop the mothers insulin from working properly. This is called insulin resistance. As the pregnancy develops and the baby grows bigger, the mothers body has to make more insulin to keep her blood glucose in the recommended glucose range.

    Later in pregnancy the amount of insulin needed to keep blood glucose levels in the optimal range is 2 to 3 times higher than usual. If the mother is unable to produce enough insulin to meet this demand then her blood glucose levels rise and gestational diabetes develops.

    No, you don’t have to fast for the screening test. You can eat and drink that day as you normally would.

    Here’s what to expect during and after the test:

    • A sweet drink: When you arrive for the test, you’ll drink a sugar solution that contains 50 grams of glucose. The stuff tastes like a very sweet soda pop , and you have to get all of it down in five minutes. Some providers keep it chilled or let you pour it over ice and drink it cold.
    • A blood draw: An hour later, a blood sample is taken to check your blood sugar level. The result indicates how efficiently your body processes sugar.
    • Results: These should be available in a few days. If the reading is too high, which happens an estimated 15 to 23 percent of the time, you’ll be asked to return for a three-hour glucose tolerance test to see whether you have gestational diabetes. The good news is that most women whose screening test shows elevated blood sugar don’t turn out to have gestational diabetes.
