Sleep deprivation can increase cortisol levels, which can also affect your blood sugar levels.
Do You Have To Take A Glucose Screening Test While Pregnant
The U.S. Preventive Services Task Force and American College of Obstetricians and Gynecologists recommend all pregnant people be screened for gestational diabetes. It’s more important now than ever before, given the increasing numbers of pregnant people affected by obesity and a sedentary lifestyle.
Detection and treatment of gestational diabetes can reduce the risk of pregnancy complications like preeclampsia, an overly large baby, high blood pressure, and C-section. “Studies show a significant reduction in serious complications with treatment of gestational diabetes,” reiterates American Family Physician in a review of ACOG guidelines.
Early gestational diabetes screening is recommended for people with certain risk factors, including a history of gestational diabetes, obesity, and known impairment to glucose metabolism, according to American Family Physician.

What Do The Results Of The Glucose Tests Mean
As the normal range for blood sugar levels detected in the glucose challenge test and the glucose tolerance test may vary depending on the lab or clinic, your provider will be your best resource for information and advice on your specific results and recommended next steps in your pregnancy. However, these general guidelines may apply:
What Does The Blood Glucose Test Involve
All pregnant women are offered this screening test between 24-28 weeks gestation. When other risk factors are present, such as obesity, the test may be offered earlier and then repeated if initially normal. The screening test for GD is called a glucose challenge, which aims to see how your body is handling sugars. The measurement is taken 1 hour after you consume a glucose drink. This test can be conducted at any time of day as it is not a fasting test. If your blood sugar is normal after the challenge, you will not require any more testing. If it is high, you will have a second test. This test is done in the morning while you are fasting and will require you not to eat prior to the test. You will have your glucose tested before consuming a glucose drink and then tested again 1 and 2 hours later. If your glucose is higher than specific cut-off values, it means you have GD. See the table for more specific information.

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.

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.
What Happens If You Fail The 3 Hour Glucose Test
Then you now have yourself a diagnosis of Gestational Diabetes.
If you are like me, you might feel pretty devastated and depressed at first. I felt like I had totally failed my child and my body.
I do my best to exercise regularly and be healthy though Id be lying if I said I didnt enjoy a Lindor Lindt truffle from time to time.
A month before I got pregnant, my A1C was 4.7%, which is actually just above being too low. My fasting blood sugar was excellent.
However, the first thing my dietician said to me was, I want you to know that this is NOT your fault. While there are risk factors, you really dont fit into those categories, so Im confident that this is purely a placenta issue.
The Mayo Clinic says:
During pregnancy, the placenta, which connects your baby to your blood supply, produces high levels of various other hormones. Almost all of them impair the action of insulin in your cells, raising your blood sugar. Modest elevation of blood sugar after meals is normal during pregnancy.
As your baby grows, the placenta produces more and more insulin-counteracting hormones. In gestational diabetes, the placental hormones provoke a rise in blood sugar to a level that can affect the growth and welfare of your baby. Gestational diabetes usually develops during the last half of pregnancy sometimes as early as the 20th week, but generally not until later.

Glucose Tolerance Test Results
Itâs worth knowing that approximately 66 percent of pregnant women who take the glucose tolerance test end up not being diagnosed with gestational diabetes. So, just because your provider has ordered a glucose tolerance test during your pregnancy doesnât automatically mean you have gestational diabetes.So, what do the results of the glucose tolerance test indicate? Four blood samples are drawn during a glucose tolerance test. If just one of the four results is higher than normal, your provider may recommend that you make subtle changes to your current pregnancy diet. The provider may have you take another glucose tolerance test after youâve made those changes to check if the results have improved.If more than one of the results is higher than normal, your provider may determine that you have gestational diabetes. The following figures indicate higher than normal blood sugar levels:
Fasting blood sample: Higher than 95 mg/dL
1-hour blood sample: Higher than 180 mg/dL
2-hour blood sample: Higher than 155 mg/dL
3-hour blood sample: Higher than 140 mg/dL .
If itâs determined that you have gestational diabetes, your healthcare provider can help guide you in making changes to help manage it. Eating a healthy diet, exercising during your pregnancy, and taking medication prescribed by your provider have been shown to help control blood sugar and to help keep you and your baby healthy.
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.

Normal Blood Glucose Levels For Diabetics
Normal blood sugar ranges in healthy non-diabetics. For a person without any type of diabetes, blood sugar levels are generally between 70 to 130 mg/dL depending on the time of day and the last time they ate a meal. Newer theories about non-diabetic blood sugar levels have included post-meal blood sugar levels as high as 140 mg/dL.

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.
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.

What Is The Optimal Method Of Diagnosis
Since there is no clear glucose threshold above which pregnancy outcomes responsive to glycemic management occur , controversy persists as to the best diagnostic thresholds to define GDM. The International Association of the Diabetes and Pregnancy Study Groups Consensus Panel decided to create new diagnostic thresholds for GDM based on data from the Hyperglycemia and Adverse pregnancy Outcome study. IADPSG thresholds are the maternal glucose values from HAPO associated with a 1.75-fold increase of LGA, elevated C-peptide, high neonatal body fat or a combination of these factors, compared with the mean maternal BG values of women studied in HAPO. These arbitrary thresholds, when applied to the HAPO cohort, led to a GDM incidence of 17.8%. The National Institute of Health 2013 Consensus Conference summary statement stated that at present, the panel believes that there is not sufficient evidence to adopt a 1-step approach, such as that proposed by the IADPSG . However, since this publication, national organizations have published guidelines that are divergent in their approach to screening and diagnosis of GDM , thus perpetuating the international lack of consensus on the criteria for diagnosis of GDM.

Why Did I Fail
There are many reasons why a mom-to-be has failed the first glucose test.
The first one being that you do actually have Gestational Diabetes.
The second being that the levels for failing are actually pretty low depending on your office, to fail, you have to have a level above 130 or 140.
When you take the three hour test , the level to fail the one hour is 180.
The point of the screening is to catch a wide net to make sure they dont miss anyone who *might* have Gestational Diabetes.
Because if theres any chance you do have it it needs to be caught and treated. Unmanaged Gestational Diabetes typically has the worst outcomes.

Will The Glucose Tests Make Me Feel Sick
Some moms-to-be feel nauseated after drinking the glucose solution, and a few even throw up. It may help to eat something a few hours before the screening test. If you vomit soon after you’ve gotten the drink down, you’ll have to come back on another day and repeat the test.
It’s actually more common for women to feel sick during the three-hour glucose tolerance test, because the solution for that test is twice as sweet or contains twice as much liquid as the one for the screening test, and you have to drink it after fasting.
