What is a failed glucose test number?
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.
What is a passing glucose test for pregnancy?
According to the Mayo Clinic: Blood sugar level below 140 mg/dL is normal and considered passing. (Note that some doctors use a threshold of 130 mg/dL) Blood sugar level between 140 mg/dL and 190 mg/dL is elevated, and requires the follow-up three-hour glucose tolerance test to confirm gestational diabetes.

It is important not to miss the diagnosis of gestational diabetes as there is increased risk to both mom and baby. Moms have an increased risk of blood pressure problems, preeclampsia or toxemia of pregnancy and long term are at higher risk of type 2 diabetes.
What happens when you fail a pregnancy?
You “failed”. What does that mean and what happens now? During pregnancy the placenta starts releasing a hormone that makes women insulin resistant. Most of the time the body can still maintain blood sugars in a normal range, but approximately 6% of the time is pushes women over into diabetes.
Is a fetus at risk for growth problems?
The fetus is at risk of growth problems, birth trauma such as shoulder dystocia, bone fracture and nerve palsy, as well as higher chance of still birth. Scar y as all of these issues are, they are largely avoidable if diabetes is diagnosed and well controlled.
Is gestational diabetes a fun test?

What happens if a baby has GD?
In terms of your baby being at risk, if you had uncontrolled GD (which is a big if) there would be a slightly increased risk of developing type 2 later in life and perhaps an increased risk of obesity, but not enough to spend time worrying about. If you teach good nutrition during his childhood and make sure he gets a healthy amount of exercise, that will probably have way more impact in the long run. Plus there is no proof that you did have GD, if you passed the 3-hour solidly (meaning all 4 of your values were in the normal range?). A 10.5-lb. baby does not automatically mean you had GD -- some babies are just going to be that size.
Can GD cause a baby to grow?
That's a perfectly legitimate question. I believe the answer is that uncontrolled GD can cause your body to grow a baby that is too big for you to birth safely. For example, there was a news story a year or two ago about a 19-lb. baby being born (I forget where, it was somewhere in Southeast Asia if I remember correctly). Now that was probably a woman who had preexisting type 2 and was unaware of it, but it's an illustration of what prolonged exposure to very high blood sugar can do to a baby.

What is the A1C range for gestational diabetes?
PS – In-the-know docs will test your first trimester A1c as an alternate way to screen for GD. Anything in the prediabetic range (5.7% or above) is considered gestational diabetes. You can also request your doctor check your A1c if it’s not on their radar. That’s what I did.
Why does the pancreas need to be pumped out during pregnancy?
Your pancreas, the organ that produces insulin, undergoes dramatic changes in pregnancy as it prepares to pump out at least triple the amount of insulin (this is to overcome the innate insulin resistance of late pregnancy and to keep your blood sugar in that nice 20% lower than usual zone). In order to do this, the pancreas needs enough of certain amino acids, suggesting that inadequate protein consumption during the first trimester is a risk factor for gestational diabetes. (Nat Med. 2010)
What is the A1C in the first trimester?
The first trimester is before the onset of insulin resistance and when blood sugar levels in pregnancy are typically lowest. Another study found an early pregnancy A1c of 5.9% or higher is linked to a 3-fold higher rate of macrosomia (large baby) and preeclampsia.
What is the A1C in pregnancy?
One study that measured average blood sugar in early pregnancy via a test called hemoglobin A1c (or just A1c for short), found that an elevated first trimester A1c was 98.4% specific for detecting gestational diabetes.

Is gestational diabetes controversial?
Gestational diabetes is controversial. It’s complicated. And there’s a lot of misinformation out there.
Does blood sugar affect pregnancy?
The bottom line is: your blood sugar levels in pregnancy matter. Clearly, the adverse “fetal programming” typically attributed to gestational diabetes may be occurring to mothers who experience only slightly elevated blood sugar. This means what you eat matters, the amount (and quality) of carbohydrates you eat matters, the amount of sugar you eat matters, the amount of nutrients that naturally regulate blood sugar matters, the amount of sleep you get matters, the amount of exercise you get matters, etc, etc, etc.
What is gestational diabetes?
Gestational diabetes is high blood sugar (glucose) during the second and third trimester of pregnancy. The exact cause is unknown. It may be a combination of factors, including genetics, increased hormones triggered by pregnancy that lead to insulin resistance, and an inability to produce the extra insulin that’s needed to compensate. “By week 26 of pregnancy, women need about two times more insulin than normal to properly regulate blood sugar,” says Alyssa Bixler, diabetes program coordinator at OhioHealth McConnell Heart Health Center. “This need nearly triples by the end of pregnancy. For some women, this demand on the body is too much.”
How long after pregnancy is a baby more likely to have diabetes?
Bixler says the risk for Type 2 diabetes increases along with age. It’s more likely to occur in the mother within 10 years after pregnancy, and in her child anytime in adolescence or adulthood.
Why do I need a glucose test?
A glucose test during pregnancy checks to see how well your body’s cells absorb sugar. The test measures the amount of sugar in your blood after consuming a specific amount of sugar in a particular time period. A high level of glucose may indicate that you have gestational diabetes.
How are the first and second glucose tests different?
The first glucose test is usually a one-hour test that does not require fasting. You will drink a 50-gram glucose drink, wait one hour and then have your blood drawn at your doctor’s office or a laboratory. Results from both tests are available within 24 hours. If your first test results are high, your doctor will request a three-hour glucose test, for which you’ll have to fast and drink a 100-gram glucose drink . You’ll then have your blood drawn after one hour, two hours, and three hours.
Are there ways to “pass” a three-hour glucose test?
Some people try to trick the three-hour test to get a passing value by changing their diet. It’s very important that you don’t do this. It can be dangerous for you and your baby. Remember, an abnormal test result is nothing to be ashamed of. It doesn’t mean you’re failing you or your baby. The test just helps your doctor know how to best care for you and your baby during throughout the rest of your pregnancy.
Can you fail your first glucose test and pass your second?
Yes, it’s possible to fail your first glucose test, but not fail your second test. This just means that you probably don’t have gestational diabetes.
Does gestational diabetes go away after pregnancy?
Yes. While there is no way to get rid of gestational diabetes while pregnant, in most cases, it will go away within hours after birth. Your doctor will do a blood sugar test after delivery, and again at six weeks after birth.
