Gestational diabetes is a condition in which your body has too much sugar in the blood. Seven out of every 100 pregnant people will develop it, according to , and this can lead to problemsfor both the expectant parent and baby. Gestational diabetes can cause problems with fetal growth, as well as increase the risk for C-section and high-risk conditions like preeclampsia.

Luckily, glucose screening and glucose tolerance testing can help you detect gestational diabetes early, and it gives you a chance to minimize the risks of this condition. Find out everything you need to know about glucose screening tests, from what they are to when they’re administered.

When Is The Glucose Screening Test Taken During Pregnancy

You typically get a glucose screening test between 24 and 28 weeks of pregnancy. However, your provider may want you to be screened earlier than 24 weeks if a routine urine test shows a high level of sugar in your urine or if you’re considered high risk. If the results are normal, you’ll be screened again at 24 to 28 weeks.

Of course, if you were diagnosed with diabetes before pregnancy, you won’t need to be screened. Instead, you’ll continue to work with your provider to manage your condition during pregnancy.

    How Is Gestational Diabetes Diagnosed

    Most women are diagnosed using a pathology test, which requires blood samples to be taken before and after a glucose drink. This is known as a pregnancy oral glucose tolerance test . This test is usually performed between 24 and 28 weeks into the pregnancy, or earlier if you are at high risk.

    A pregnancy oral glucose tolerance test involves:

    • fasting overnight
    • having a blood test in the morning
    • having a drink containing 75 grams of glucose
    • having a blood test one hour after having the drink
    • having a blood test 2 hours after having the drink.

    Gestational diabetes is diagnosed if any of the results from the test show that your blood glucose is raised.

    During COVID-19, further diagnostic guidelines have been added as alternatives to the OGTT where this cannot be performed due to a contagion risk. Check with your doctor or hospital about current guidelines.

    GD is increasingly common, with about 7% of women having the condition. If you are found to have GD, you will work closely with your health care provider to keep your blood glucose levels in a healthy range. This involves choosing a healthy diet, gaining the recommended weight during your pregnancy, getting exercise, and if needed, taking insulin or pills to lower your blood sugar. Your babys wellbeing will be carefully monitored by regular measurements of growth and amniotic fluid volume. If you have GD you will be offered a repeat glucose tolerance test between 6 weeks and 6 months postpartum to detect prediabetes and diabetes. You may also be offered induction between 38-40 weeks of pregnancy. Finally, it is strongly recommended that women with GD breastfeed their infants.

    A reading higher than 7.7 millimoles/L on the gestational diabetes chart calls for further follow-up testing, often called the glucose tolerance test. A reading higher than 11.1 millimoles/L likely means a gestational diabetes diagnosis.

    The night before my third visit to the lab, my husband asked me what would happen if I just skipped the test. I didnt knowI assumed it was mandatory.

    Risks And Side Effects

    Most people do not experience any side effects from glucose testing, and serious complications are rare.

    As it involves fasting and blood testing, the glucose tolerance test might cause nausea, light-headedness, shortness of breath, and sweating in some people.

    More serious but less common risks include:

    • excessive bleeding

    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.

    How Do You Manage Gestational Diabetes

    If you are diagnosed with gestational diabetes, it is important that you are supported and know what to do to manage it. Health professionals such as your doctor, a dietitian, a diabetes nurse educator, or sometimes, a diabetes specialist will help you understand what to do and will support you.

    Family also can be a great support. It is important that your family understands gestational diabetes and how it is managed.

    Management of gestational diabetes aims to keep blood glucose levels in the recommended range during pregnancy. This can prevent problems during birth and also helps reduce the babys risk of being overweight in childhood and developing type 2 diabetes later in life.

    Management of gestational diabetes involves:

    • monitoring blood glucose levels
    • healthy eating. Referral to a dietitian is an important part of management. Often this will be organised for you via your health care team
    • regular physical activity

    Some women may need insulin injections to help manage their gestational diabetes.

    How Is The Glucose Screening Test Done Do I Have To Fast

    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.
