WHILE YOU WAIT
Your body is already
putting baby first.
Now we get to see just how much.
Here is what is really going on while you sit here.
What you just drank
50 grams of sugar. That is about 45 jelly beans worth, swallowed in five minutes.
Nobody would drink this for fun. That is the whole idea. It is a stress test. Your body has to deal with a lot of sugar all at once, and the blood draw shows how it did.
What is going on right now?
Tap where you are.
-
// First 15 minutes
The sugar hits
All of it is moving from your stomach into your blood, much faster than food normally would. If your stomach feels off, that is why. It is usually worst right now, and then it settles.
-
// 15 to 45 minutes
Your body goes to work
Your body makes insulin. Insulin's job is to move sugar out of your blood and into your muscles, where it gets used for energy.
Here is what is different now that you are pregnant: you need about two to three times more insulin than you used to, just to do the same job.
-
// About 60 minutes
The blood draw
The number shows how high your blood sugar went, and how much of it your body has already cleared out.
It is not a score on how you eat. It is a picture of how your body handled something almost nobody eats in real life.
There is nothing here to fail
You cannot
study for
this one.
You cannot
practice.
People say they failed the glucose test. It is worth noticing how odd that is.
What it measures is how your body is handling pregnancy right now, and most of what is driving it is an organ you grew for your baby.
A high number means your body could use some help with sugar. It does not mean you did something wrong.
Your hour.
- 1Stay in your seat. Even a short walk can change your number.
- 2Ask about water. Most places let you drink it while you wait.
- 3If you feel faint or unwell, tell the staff right away. In an emergency, call 911 or your local emergency number.
- 4Eat something with protein after, before you drive home.
If you feel faint or unwell, tell the staff right away. In an emergency, call 911 or your local emergency number.
Your first test came back high
Hold onto this: it is a second look, not a diagnosis.
The first test is set up on purpose to catch more women than actually have anything. Looking twice is better than missing someone. Most women who take the longer test turn out to be fine.
What that first number did tell your doctor is that your body is working harder than usual to handle sugar. Every pregnant woman's body works harder at this. The longer test shows how much harder yours is working.
What the day looks like
You will not eat overnight. When you arrive they draw your blood before anything else. Then you drink the sugar drink. Then they draw your blood again at one hour, two hours, and three hours.
Four draws in all. Plan on being there about four hours.
Book the earliest appointment you can get. You will be going without food, and a morning slot keeps that stretch as short as possible.
What to bring, and why
- 1A phone charger. You will be there four hours and mostly on your phone. This is the one everybody forgets.
- 2Something warm. Waiting rooms run cold, and going without food makes you feel colder.
- 3A snack with protein in it. For after the last draw. You will be starving, and protein steadies you better than sugar does.
- 4Something to do. Headphones, a book, shows downloaded before you go. Four hours is longer than it sounds.
- 5A water bottle. Most places let you drink water, and it makes the blood draws easier too. Ask when you arrive.
- 6A ride, if you can. Some women feel lightheaded afterwards.
The night before
Nothing to eat after midnight, or whatever time your clinic gives you. Water is fine, and drinking plenty of it actually makes the blood draws go easier.
If you feel unwell on the day, or you cannot keep the drink down, tell them. The test can be done another day. That is a normal thing to happen, not a failure.
Why you are here
Your first test came back high. So far, that is the only thing it means.
That first number told your doctor something real: your body is working harder than usual to handle sugar. Every pregnant woman's body works harder at this. Today is about finding out how much harder yours is working.
Most women who take this longer test do not have gestational diabetes. The first test is set up on purpose to catch more women than actually have it, because looking twice is better than missing someone.
What you just drank
100 grams of sugar. About 90 jelly beans worth. Double the first test, on an empty stomach, in five minutes.
With nothing else in your stomach to slow it down. If you feel rough, that is a fair response to what just happened, not a sign of anything.
What happens between your draws?
Tap where you are. Come back as you go.
-
// First draw
Before you drink anything
This one shows where your blood sugar sits after a night without food. It is its own separate piece of information. For some women this is the only number that comes back high, and it is an important one.
-
// One hour
The high point
The sugar is in your blood and your body is working hard. It is making insulin to move that sugar into your muscles, and in pregnancy it has to make two to three times more than it used to. This number shows how high you went.
-
// Two hours
The interesting one
By now a body that is keeping up has started bringing the sugar back down. This number is less about how high you went and more about how well you are coming back, which is the harder part.
A short test can never see this. That is the whole reason today takes so long.
-
// Three hours
Nearly back to normal
By three hours most people are close to where they started. If you are not, that is worth knowing, and there is no way to find it out except by sitting here. Then you are done.
Nothing you ate caused this
Women get this diagnosis after months of eating carefully. Women avoid it after eating badly.
Gestational diabetes is not caused by eating sugar, by gaining weight, or by doing anything wrong.
It comes from hormones made by your placenta, the organ feeding your baby. Those hormones make it harder for your insulin to work, so more sugar stays in your blood and reaches the baby. Every pregnant woman's body does this.
In some women the body cannot quite keep up with the extra work. Whether yours can is mostly about how your own body is built, and some of that was settled long before this pregnancy started.
This test is not a judgment on anything you have done.
Your four hours
- 1Stay in your seat between draws. Even walking the hallway can change your numbers.
- 2Ask about water. It is usually allowed, and drinking it makes the draws easier.
- 3Nothing else until after the last draw. No gum, no mints, no tea. It all counts.
- 4Eat the protein you brought before you drive home. You have not eaten since last night.
- 5Lightheaded, sweaty or shaky?Tell someone right away. It happens a lot and they would rather know.
Questions worth asking your doctor
Whatever today's number says, your first test picked up something real. Your body is working harder with sugar than it used to. That is worth a conversation.
- My first test was high. Does that mean anything on its own?
- Is there anything I should change about how I eat?
- Should I be checking my blood sugar at home?
- What should we keep an eye on for the rest of my pregnancy?
- Is there anything I should do after the baby comes?
That last one matters more than most people realize. What happens with sugar during pregnancy can say something about your health years from now, and it is the question almost nobody thinks to ask.
