How To Pass Glucose Tolerance Test Pregnancy?

As much as conceiving is a blessing, one has to undergo various challenging things over the 9 months of pregnancy. Personally, before conceiving I wasn’t aware that one has to undergo a glucose screening pregnancy test. Maybe it is, for this reason, I failed my first screening test and had to undergo the glucose tolerance test? So, what does it take to pass the glucose tolerance test?

To begin with, 1 in 10 pregnant women will be diagnosed with gestation diabetes. Statistically speaking, the percentage is even lower with only 5-10% of the women being diagnosed with GD (gestation diabetes), which is a high blood sugar condition. Ironically, one out of two women will fail the glucose screening pregnancy test only to pass the tolerance test booked later. That’s about 50%?

Why you should ensure you pass the glucose screening pregnancy test?

Pregnant women have a lot to deal with. The hormonal changes, ever expanding belly, morning sickness and being stared at in public. Hello, let’s face it. Human beings have a tendency of staring at pregnant women in public. But, why shouldn’t they? I mean you are carrying the evidence of sex in public. You know how sex is a sensitive issue to most people?

Moving forward, this article shall walk you through the whole process of the glucose screening pregnancy test and provide reasonable ways in which you can adopt and pass the tests. However, in the meantime let’s evaluate the various why it is necessary to pass the glucose test.

The normal blood glucose level is 120md/dl. Anything above that would mean that you need further tolerance or be diagnosed with gestation diabetes. Being diagnosed with gestation diabetes will open you to unnecessary early induction, C-section and not mentioning the fact that you will have to be put on a diabetic diet meaning that every now and then you will have to monitor your blood sugar level. All these are necessary since you will avoid complications on your pregnancy. However, try and think of a scenario where you get diagnosed with gestation diabetes just because you ate something that you shouldn’t have before the glucose tolerance test. It sucks, right?

The Glucose Screening Pregnancy Test

Personally, on my first pregnancy, I failed the glucose screening test with my blood sugar level being diagnosed as 150md/dl. This subjected me to another 3 hours the glucose tolerance test. If you thought that the one-hour glucose screening test sucks wait until you fail the test, trust me you would like the follow-up glucose tolerance test.

What to expect?

I don’t know if this only applies to me but I really hate needles. Honestly, they really freak me out. When undergoing the glucose screening pregnancy test you have to embrace yourself and face your fear of needles. More often than not the test is done in the morning, you are asked to take 8 ounces of a sweet soda like liquid or rather fluid.

So, far things sound pretty interesting, right? I mean what to go wrong with taking a sweet substance for a test? Well, the sweet soda isn’t given to you for entertainment. After one hour a blood sample shall be taken from you. Okay, I understand, things are starting to turn stale pretty fast, right? A couple of tests are run on the blood sample to see how your body handles high glucose concentration and, if the results are anywhere between 140-200md/dl, it's bad news for you. You have to undergo a glucose tolerance test.

For what is worth, the test is crucial to ensure that both you and your developing baby are safe from gestation diabetes. And if diagnosed with the condition with proper medical care there will be no complications. Still on the same test if your results are anything above 200md/dl. You are automatically diagnosed with gestation diabetes.

The good thing about this test is that there is a particular diet that you can adopt and pass the glucose screening pregnancy test. However, this only works if you don’t have gestation diabetes. If by any chance you have the condition you shall fail the test even after adopting methods to help you pass the test. On the brighter side, if you don’t have the condition this will save you the three hours of agony. And, yes the glucose tolerance test takes 3 hours.

The Glucose Tolerance Pregnancy Test

On both two of my pregnancies, I failed the one-hour glucose screening test and had to book an appointment for the glucose tolerance test. The second trimester is the most peaceful moment of the pregnancy, right? By this time you have adapted to the various hormonal changes, morning sickness isn’t as severe as before, it is also during this time that you start feeling your baby kick. Peaceful, right!?

It is also during the second trimester (24 -30 weeks) that you have to undergo the glucose tests. I remember before going for the test I was so stressed that I nearly lost my appetite. Things became even worse when I failed the first test and had to be booked for glucose tolerance test. Well, it’s a fact, I can’t deny the fact that I don’t like needles but after failing the screening test I got worried that there might be a possibility that I have gestation diabetes.

What to expect?

On the eve of the glucose tolerance test, one is asked not to eat anything. Considering the fact that I used to eat a lot, to me this was too much to ask but I had to follow the doctor’s instructions. The test is booked in the morning and on arrival, a blood sample is taken from you and tested. This is to test your fasting glucose level.

Hey, it’s not over yet. Remember I said the test takes 3 hours? Well, things just got started, you might want to bring your phone and play Candy Crush so as to ensure you don’t get bored. Your doctor will then give you an even sweeter soda like fluid and will take blood samples from you after every hour. That means on the tolerance test there shall be a total of 4 blood samples taken. And, that means 4 needles??

If one of the results is abnormal your doctor will advise you on a routine to ensure you rectify the condition. However, if two or more of the samples taken give abnormal results you are diagnosed with gestation diabetes.

What to do to ensure that you pass the glucose tolerance test?

1. Avoid high sugar foods before going for the test. Instead take healthy carbohydrates, carbs, and proteins. Carbs include Wheat bread, grains, and fresh fruits. Carbs help reduce the rate at which the body absorbs sugar and taking it an hour before the test can be what you just need to avoid the agonizing 3 hours of the glucose tolerance pregnancy test.

2. Ensure you don’t go for the test on an empty stomach. After failing the glucose screening test on my first pregnancy, on my second pregnancy, I thought if I failed to eat this would help me pass the glucose screening test. Well, I was in for a big disappointment. I tested positive and had to undergo the tolerance test only to be diagnosed negative later.

3. Follow the doctor’s instructions. If your doctor advises you not to take a certain fruit or meal. If you want to pass the test it would be for your good interest that you don’t.
