Can You Decline The Glucose Test In Pregnancy
If you decline the glucose test, then we will need to check your blood sugar levels 4 times per day for at least 1 week.
This will require you to prick your finger when you wake up every morning and one hour after breakfast, lunch, & dinner.
This is an alternative way to screen for gestational diabetes.
Are There Any Risks
While the test itself does not come with any real risk, there are certain risk factors for developing gestational diabetesincluding being over the age of 25, having a family history of diabetes, and/or being obese. That said, half of those who develop gestational diabetes have no known risk factors, making testing is so important.
Can I Eat And Drink Before Having A Blood Test
It depends on the type of blood test you’re having. The healthcare professional arranging your test will tell you if you need to do anything to prepare for it. You can eat and drink as normal before some blood tests. But if you’re having a “fasting blood test”, you will be told not to eat or drink anything beforehand. You may also be told not to smoke before your test. Common fasting blood tests Examples of blood tests that require you to fast include: a fasting blood glucose test you fast for 8 to 10 hours before the test an iron blood test you fast for 12 hours before the test For more information about a wider range of blood tests, go to Lab Tests Online.

I Have The Results Of My Glucose Screening Test What’s The Normal Range For Blood Sugar
Different providers use different standards for determining whether your level is too high. Some will say that if your one-hour blood sugar level is 140 milligrams of glucose per deciliter of blood plasma or more, you need to have the glucose tolerance test. Others put the cutoff at 130 mg/dL to catch more women who may have gestational diabetes, even though there are likely to be more false positives this way.
If your blood glucose level for this screening is higher than 200 mg/dL, most providers will consider you diabetic and you won’t be required to take the glucose tolerance test.
But any score between 140 and 200 means that you’ll have to take the three-hour glucose tolerance test for a definite diagnosis.
Prep Before The Glucose Tolerance Test
If your provider has scheduled a glucose tolerance test during your pregnancy, you will be given fasting instructions. This means you probably wonât be able to eat or drink anything except for small sips of water for about 8 to 14 hours before the test.You may find it convenient to schedule a morning appointment for the glucose tolerance test so that you can fast overnight. You will need to stay at the lab or clinic for the full procedure, so you might consider bringing something to read or do or having your phone fully charged so that you can occupy yourself during that time.

Glucose Screening Tests During Pregnancy
TWO-STEP TESTING During the first step, you will have a glucose screening test: You DO NOT need to prepare or change your diet in any way. You will be asked to drink a liquid that contains glucose. Your blood will be drawn 1 hour after you drink the glucose solution to check your blood glucose level. If your blood glucose from the first step is too high, you will need to come back for a 3-hour glucose tolerance test. For this test: DO NOT eat or drink anything for 8 to 14 hours before your test. You will be asked to drink a liquid that contains glucose, 100 grams . You will have blood drawn before you drink the liquid, and again 3 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked. Allow at least 3 hours for this test. ONE-STEP TESTING You need to go to the lab one time for a 2-hour glucose tolerance test. For this test: DO NOT eat or drink anything for 8 to 14 hours before your test. You will be asked to drink a liquid that contains glucose . You will have blood drawn before you drink the liquid, and again 2 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked. Allow at least 2 hours for this test.Continue reading > >
The Diabetes Doctor Has Recommended Starting Insulin What Should I Do
Insulin is safe in pregnancy and can help control your blood sugar and reduce some of the risks described above.
If you are started on insulin, let your doctor know. Pregnant women become diabetic in pregnancy because their placenta is making a hormone that makes it harder for them to metabolize sugar. If you find that you are on a certain dose of insulin and then the dose needs to be decreased, this could be a sign that the placenta is starting to get old and you should let your doctor know. It is okay if the insulin requirements keep going up.
It is generally recommended that if you have gestational diabetes requiring insulin, you should have labour induced at 38-39 weeks because of the risk of stillbirth after this. If you do not require insulin to control your sugar you probably do not need to be induced early. Speak to your care provider for more details.

Choose Healthy Carbohydrates Instead
Complex or unrefined carbohydrates such as whole grain breads and cereals, whole fresh fruits and even baked potatoes are absorbed more slowly into your bloodstream and are less likely to give you the large sugar jolts that can result in excess glucose filtering into your urine.
In fact, since complex carbohydrates contain more fiber, they actually slow the absorption of sugar into your bloodstream. Whats more, they provide lots of essential nutrients for pregnancy .

Why Do I Need A Glucose Screening Test During Pregnancy
Most healthcare providers routinely recommend a glucose screening test to check for gestational diabetes.
Gestational diabetes is a high blood sugar condition that some women get during pregnancy. Between 2 and 10 percent of expectant mothers develop this condition, making it one of the most common health problems during pregnancy. And because the condition rarely causes any symptoms, testing is the only way to find out whether you have it.
The GCT is a screening test, which means it won’t give you a diagnosis. Instead, it’s designed to identify as many women as possible who might have gestational diabetes but need more testing to find out. So a positive result doesn’t mean that you have gestational diabetes.
In fact, only about a third of women who test positive on the glucose screening test actually have the condition. If you test positive, you’ll need to take the glucose tolerance test a longer, more definitive test that tells you for sure whether you have gestational diabetes.
Some providers skip the glucose screening test altogether and instead order a shortened version of the glucose tolerance test, which is also called a one-step test .
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.

Who’s At Risk Of Gestational Diabetes
Any woman can develop gestational diabetes during pregnancy, but you’re at an increased risk if:
- your body mass index is above 30 use the BMI healthy weight calculator to work out your BMI
- you previously had a baby who weighed 4.5kg or more at birth
- you had gestational diabetes in a previous pregnancy
- 1 of your parents or siblings has diabetes
- you are of south Asian, Black, African-Caribbean or Middle Eastern origin
If any of these apply to you, you should be offered screening for gestational diabetes during your pregnancy.
Glucose Challenge Test Results
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.

What Is Gestational Diabetes
Gestational diabetes is a type of diabetes that occurs during pregnancy. It happens when your body is not able to produce enough insulin to keep the amount of glucose in your blood at proper levels. Untreated GD increases the likelihood of having a large baby, and is associated with birth complications as well as health risks for the newborn . Untreated GD also increases the risk of stillbirth late in pregnancy . Women who develop GD are at higher risk of developing type 2 diabetes in the future. However, there is excellent treatment for GD, and most women diagnosed with GD have normal deliveries and healthy babies.
How To Pass The 3 Hour Glucose Tolerance Test
Just like the 1 hour glucose test, there isnt any special way to ensure that you pass the 3 hour oral glucose tolerance test aka the ogtt.
Your best bet is to eat a well-balanced diet leading up to the test and minimize the consumption of simple carbs like cereal, white flour, juice, and soda.
Making these changes the night before or the week before is unlikely to make a big difference. You should make these changes months in advance.
Its also a good idea to try and maintain these habits postpartum as well. Unfortunately, 60% of women with gestational diabetes will develop Type 2 diabetes later in life.

The Third Thing You Need To Do Is To Try And Get Adequate Sleep For The Majority Of Your Pregnancy
I love sleep :).
It is so important for so many things. Including your sugar levels.
Let me explain a little further.
Sleep deprivation is a highly stressful situation for your body.
High stress = high epinephrine and high cortisol levels.
These hormones can increase insulin resistance and increase the available amount of sugar in your blood.
In other words, a lack of sleep can impact how your body metabolizes sugar.
Tips For Passing A Glucose Tolerance Test During Pregnancy
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.

Impact Of Adoption Of Iadpsg Criteria
Since the publication of the IADPSG consensus thresholds, there have been numerous retrospective studies that have examined the impact of adoption of these criteria. It is difficult to apply the results of these studies to clinical practice due to their retrospective nature and the wide variation in the comparison groups used. In all of these studies, adoption of IADPSG criteria has led to an increase in the number of cases diagnosed while the impact on perinatal outcomes is inconsistent . Studies comparing pregnancy outcomes before and after changing from a variety of different GDM diagnostic criteria to the IADPSG criteria show differing results. LGA was lower in 1 study and caesarean delivery was lower in several studies after adoption of the IADPSG criteria. However, others did not find reductions in LGA , and 1 study found an increase in primary caesarean section rate .
Given this lack of evidence, it is possible that the decision regarding the recommended screening method will be determined by the economic implications on health-care resources. Decision analysis modelling studies done in other countries have yielded a variety of results and many are of questionable applicability in the Canadian setting because of differing cost and screening and diagnostic strategies.

Assessment And Management Of Complications

Retinopathy. Women with type 1 and type 2 diabetes should ideally have ophthalmological assessments before conception, during the first trimester, as needed during pregnancy, and within the first year postpartum . The risk of progression of retinopathy is increased with poor glycemic control during pregnancy, and progression may occur for up to 1 year postpartum . Additional risk factors for retinopathy progression include: chronic and pregnancy-induced hypertension, preeclampsia, more severe pre-existing diabetic retinopathy , and a greater decrease in A1C between the first and third trimester of pregnancy . Closer retinal surveillance is recommended for women with more severe pre-existing retinopathy, those with poor glycemic control or women with greater reductions in A1C during pregnancy . Laser photocoagulation for severe nonproliferative or proliferative retinopathy prior to pregnancy reduces the risk of visual impairment in pregnancy if not performed prior to pregnancy, it is still considered safe to receive during pregnancy.
Although there are no intervention trials for ASA prophylaxis for the prevention of preeclampsia specific to women with pre-existing diabetes, ASA prophylaxis started between 12 to 16 weeks of gestation is likely to be beneficial, given the evidence of benefit in other high-risk populations, .

When Do You Have The Glucose Tests During Your Pregnancy
The glucose challenge test is usually performed between 24 and 28 weeks of pregnancy in women who are determined by their healthcare providers to be at low risk of gestational diabetes.If your healthcare provider has determined that you are at high risk of developing gestational diabetes, the provider may order the glucose challenge test for you earlier than the aforementioned range.If the result of the glucose challenge test comes back indicating a high level of glucose, your provider may order another testâcalled a glucose tolerance testâto more accurately diagnose your chance of developing gestational diabetes during pregnancy.If the result of an early glucose challenge test comes back indicating a normal level of glucose in your blood, your provider may order an additional glucose challenge test between 24 and 28 weeks of pregnancy.
Three Hour Glucose Results:
Most often, they want to see two of this numbers higher than those specified. If they only see one, they often will just encourage you to make dietary changes.
Personally, my fasting level was too high and they called me glucose intolerant and encouraged me to follow a diabetic diet, even if my blood sugars didnt indicate it.
I have heard that there are some places that use the A1C test. This test measures your average blood sugar level over the past 3 months. If your A1C is 6.5% or higher, you have gestational diabetes. I think this might be used by someone who cant tolerate the glucose test. However, the gold standard is drinking the glucose drink and testing your blood sugar.
If you have gestational diabetes, its important to get treated. If not, it can lead to problems for you and your baby, such as preterm labor, excessive weight gain in your baby, and increased risk of cesarean delivery.
