Early screening. Screening for diabetes in the first trimester should be considered for diagnosing overt diabetes in women who are at risk , including those with a history of previous GDM. The ability to predict abnormal results on glucose screening tests at 24 to 28 weeks and risk of continued dysglycemia postpartum are other, but less compelling, reasons cited to screen in the first trimester.

The test of choice for early screening should be based primarily on the ability to predict poor obstetrical outcomes, which may be modifiable by lifestyle or pharmacological intervention. There are 2 strategies for testing glucose levels in early pregnancyusing the nonpregnancy-recommended screening tests or using the typical 24- to 28-week gestational diabetes screening criteria . To apply nonpregnant FPG or A1C criteria in early pregnancy does not take into account that both decrease early in pregnancy and may lead to underdiagnosis in women with pre-existing diabetes. On the other hand, there has been no rigorous validation that criteria accepted for the diagnosis of GDM in the second or third trimester are appropriate for use in the first trimester.

What Is A Pregnancy Glucose Test

Before we cover what to eat before a glucose test, lets dive into some specifics about whats measured in the test and why.

A pregnancy glucose test sometimes referred to as a gestational diabetes test, measures a pregnant womans blood glucose levelsbetween 24-28 weeksof pregnancy.

If these levels are high, it may mean the body isnt producing enough insulin to manage the excess glucose from pregnancy.

This condition is known as gestational diabetes.

If youre diagnosed with gestational diabetes, your doctor will help you with a special care plan to ensure you have a healthy pregnancy.

Is There An Alternative Way To Test For Gestational Diabetes

Yes. If you do not want to drink the glucose solution for one reason or another, there is another way we can test you for gestational diabetes.

It would involve you actually checking your blood glucose through finger sticks four times a day for an entire week. This will give us a good idea of how your body processes the foods you eat.

Again, dont try to manipulate this test in any way. For example, dont try to eat really healthy for that week, then go back to eating your normal diet the subsequent week.

Just to be safe, your health care provider may have you check your finger sticks for 2 or more additional weeks just in case.

Weight gain. The 2009 IOM guidelines for weight gain during pregnancy were developed for a healthy population and little is known regarding optimal weight gain in women with GDM. Retrospective cohort studies of GDM pregnancies show that only 31.7% to 42% had GWG within IOM guidelines. Those gaining more than the IOM recommendations had an increased risk of preeclampsia , caesarean deliveries , macrosomia , LGA and GDM requiring pharmacological agents . Modification of IOM criteria, including more restrictive targets of weight gain, did not improve perinatal outcomes of interest . A large population-based study including women with GDM, concluded that while pre-pregnancy BMI, GDM and excessive GWG are all associated with LGA, preventing excessive GWG has the greatest potential of reducing LGA risk . These researchers suggest that, in contrast to obesity and GDM prevention, preventing excessive GWG may be a more viable option as women are closely followed in pregnancy.

Further studies are needed to develop weight gain guidelines for GDM patients and to determine whether weight gain less than the IOM guidelines or weight loss in pregnancy is safe. Until this data are available, women with GDM should be encouraged to gain weight as per the IOM guidelines for the BMI category to reduce adverse maternal and neonatal outcomes and postpartum weight retention.

Glucose Challenge Test Results

Connect the Dots Ginger

What many medical experts consider a normal result for a glucose challenge test is a blood sugar level equal to or less than 140 mg/dL . The mg/dL means milligrams per deciliter and the mmol/L means millimoles per liter. This is how the glucose is measured in your blood sample. A normal result means you do not have gestational diabetes.If your level is higher than 140 mg/dL , your healthcare provider may recommend you do the glucose tolerance test, which can help better determine if you have gestational diabetes or not.

Random Blood Sugar Test

A physician takes a blood sample at any time, and not necessarily when fasting. People who have serious diabetes symptoms may have this test. If blood glucose levels are 200 mg/dL at any time, this indicates that diabetes is present.

People with diabetes should monitor their blood glucose levels regularly, using a home testing kit or continuous glucose monitor.

How Can You Prepare For A Glucose Screening Test

Before your one-hour glucose test, it’s recommended to follow a diet that’s high in carbohydrates for three days so your pancreas gets accustomed to processing simple sugars. Your health care provider can give you more information on what to eat prior to testing.

Note that some people find the syrupy glucose solution unpleasant or even nausea-inducing. You can increase your odds of successfully completing the test by drinking it cold, sipping slowly over five minutes, or using an anti-nausea medication beforehand. If you still have trouble tolerating it, your OB-GYN can discuss alternatives, such as checking blood sugars for a week using a glucometer.

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.
  • Alternatives To The Glucose Test During Pregnancy

    Glucose tests are considered the gold standard for diagnosing gestational diabetes, and doctors strongly recommend that all women get the initial screening. However, we recognize that in some circumstances, including women whove had bariatric surgery, performing these tests may not be possible, says Greves.

    Klein acknowledges that people may have trouble tolerating the highly concentrated drink. She says that, instead, they may be able to use a glucometer at home to regularly self-monitor their levels and assess if theres any blood glucose dysregulation. She adds that some doctors will allow alternatives to the Glucola beverage if its something equivalent to 50 or 100 grams of glucose. Another form of simple sugar, such as jelly beans or fruit juice may be acceptable, she says. Of course, protocols vary by practice, and Klein and Greves stress that youll want to discuss options with your doctor. They may want you to stick with the tried-and-true oral glucose tolerance test.

    The initial glucose test during pregnancy is par for the course for moms-to-be. And those that need to carve out the time for the three-hour glucose tolerance test will come to realize that some minor unpleasantness is no big thing if it means keeping you and your little one on the path to a healthy delivery. Well drink to that.

    What Should I Do Before Coming For The Gtt

    As your midwife has identified a risk factor for gestational diabetes you will have been given an appointment for an oral Glucose Tolerance Test, usually at around 26/28 weeks of pregnancy.

    You will need to have two blood tests taken. The second blood test will be taken two hours after the first. You will need to remain within the clinic until the test is completed. If you walk around or go home the test will become invalid as you will be burning off the sugar you have been given.

    What Is Gestational Diabetes Mellitus

    Gestational Diabetes Test Alternatives (and How to Pass!)

    Gestational diabetes mellitus, commonly referred to as GDM, occurs only during pregnancy when hormones prevent your pancreas from releasing sufficient insulin.

    Insulin is a hormone that allows the cells to convert sugar in the blood into energy. Insulin resistance causes high levels of sugar to remain in the blood.

    Usually women with GDM have healthy pregnancies and babies. But GDM increases the risk of:

    • Macrosomia: a baby grows larger than usual, causing problems during birth and increasing the chance of induction and c-section
    • Polyhydramnios: too much amniotic fluid, causing premature labour
    • Premature birth
    • Pre-eclampsia: high blood pressure during pregnancy, which can lead to pregnancy complications if not treated
    • A baby developing low blood sugar or jaundice after birth
    • Stillbirth, although this is rare.

    Because of these factors, a glucose test is a standard pregnancy check up, to make sure all is well with you and your baby.
