1 Hour glucose first thing in am...to fast or not to fast?

momming247 · July 2015

My doctor doesn't seem to care what I do...I can't help but think it makes a difference but maybe it doesnt? What have you ladies who have passed/failed found?

rachjohn622 · July 2015

you don't need to fast but just don't eat too many carbs or foods high in sugar before. stick with proteins.

jenspeake · July 2015

Mine is first thing in the morning next week. I wasn't told anything but I will probably not eat anything in the morning until after my appointment.

mrsdhouse89 · July 2015

I've always been told to fast so the test can be as accurate as possible, so I always scheduled my appointments for first thing in the morning when I've needed to do the glucose testing.

adcoxmt · July 2015

Some offices ask that you come fasting so I did just in case. I believe I've seen a couple of other women on here who said they didn't fast, then failed the 1 hour and had to take the 2-3 hour ones...passed those just fine. So, if you're able to fast because it's in the morning, I would go ahead and do so, just to be safe.

casserole27 · July 2015

The instructions from my OB say to fast 8 hours before. Mine is in the afternoon so I am waking up early to eat something at the last possible minute.

Seems weird that your doctor doesn't have an opinion or recommendation on this, because it must make some kind of difference. If mine didn't care I probably would eat, because who wants to fast if they don't have to.

babybumb1229 · July 2015

I passed and I didn't know I was going to take it I ate pizza before going and finding out I need to do my test.

twogirlsandagreen · July 2015

With both daughters I ate eggs for breakfast, just a avoided sugar and carbs and passed

plumpous · July 2015

I ended up taking it twice because the first time they made a mistake and booked it too early in the pregnancy.

First one I did in the morning an had multi grain toast with avocado. I passes.

Second time was after work and I had eaten all day long and tried not to eat sugary foods. I failed that one by just a tiny bit, and had to take the 3 hour test.

Honestly, I have no science, but my gut says, better not to eat beforehand if you're having it early in the day.

leighann1 · July 2015

My instructions say not to fast but to avoid excessively sweet foods and drinks the day of and the day before. My appointment will be in the late morning, so I will try to eat a small, protein-heavy breakfast. And I'll be drinking my morning tea with no sugar that day

mollypuss1 · July 2015

I was told to fast for 10 hours beforehand, all I was allowed was water.

sarahakabmg · July 2015

Only protein if you eat before, do not chance with anything that is sugar, even the bread with protein I wouldn't suggest. Eggs are simple and something good for you anyway.

Random thing I have learned from a family member that does have type 2 diabetes though is if they have sugar before bed it actually helps them have a lower level when they first get up in the morning to test. So while that doesn't make me think I should eat donuts before bed, I will have probably a healthy cereal or something like that that has sugar, but low amounts.

momming247 · July 2015

Mine is first thing in the am...so I've been debating on eggs for breakfast or just zilch until after.

michellelynn6 · July 2015

My doctor does it a bit differently where she gave me the stuff to drink in advance, so I drink it whenever I want and then go to the lab within an hour. This is super convenient for me because it means I can drink it at work and then pop out for my lunch break to get my blood drawn! She said that fasting was unnecessary (unless you're doing the longer 3-hour diagnostic test!) and that if I eat before it, I should eat protein, not anything sugary or sweet because it can throw off the results.

vamomtobe · July 2015

My doctor gave me instructions to fast. DH has T1 diabetes, so one thing I've learned is that when you eat carbs with a protein, your body metabolizes the carbs at a more steady rate. So when he snacks to keep his blood glucose up (unless it's really low and he needs to raise it in a hurry), he has a protein/carb combo. Like fruit and nuts, or cookies and milk. Definitely not speaking as an expert by any means, but it seems like eating protein before your glucose test could have an effect on the outcome.

mommy_wife_nurse · July 2015

Mine was at 10 in the morning, and I passed. I ate a blueberry muffin and eggs that morning. It's more of a test on HOW your body processes the glucose, so even if you eat beforehand, it shouldn't affect it too much. My Dr said you're going to pass or fail, and the food doesn't affect it too much. Whether or not that's true for everyone, I'm not sure. Good luck, though!

VallieS86 · July 2015

I plan on eating eggs before hand. My appointment is at 8am next week. Coworker said to eat lots of protein day before. Try not to eat a lot of carbs or sugar. I've heard sometimes people who don't eat get sick from the drink so that's why I'm just going to do the eggs. Better than nothing.

babymazzei · July 2015

Because yours is in the morning, I would say fast. My doctor said I didn't have to for the first one and I failed after taking it late in the day. My doctor believes it was inaccurate because I didn't fast. (Well why didn't you tell me to? Lol)

I just had my three hour test today after fasting for 8 hours. I'm really prone to fainting and feeling weak with blood work so it was hell, but I do feel a lot better about it now. I won't know my results for a few days.

You're definitely more likely to have a false positive from something you ate before than if you were to fast.

momma=z · July 2015

I failed my first one and was diagnosed at eight weeks. Now that I know how GD works I would advise you to eat a high protein breakfast and avoid sugars and most carbs if possible, that includes fruit. If you plan on fasting I would have some dairy and/or protein before bed (cheese, plain yogurt, nuts). What you eat the night before will affect your glucose levels in the morning. In fact, waiting too long to eat will also throw off your numbers which is why a snack before bed is helpful. Good luck!

kaitlynn80 · July 2015

I failed my 1 hour after eating breakfast and lunch and going in. I had to go back for the 3 hour test which was not fun! I fasted for the 3 hour test and passed.

bcooper81 · July 2015

I passed the 1 hour and I fasted for 2-3 hours before going. So I would say fast

Exactly what my doctor said and what my process is! She also said if I do eat just to stop eating about 20 minutes before I start drinking the drink.

xpaperx · July 2015

This is so interesting. I have mine in the morning too. The label the dr put on the bottle says to eat normally. I pulled that off and the label from the company says to fast. I will be eating a protein breakfast and having my coffee with real sugar after the test.

danixbanani24 · July 2015

Clearly everyone is different! My doctor is like OPs in that she didn't really specific fasting or no fasting. She told me to do what I normally do. I booked it for the morning and typically I don't eat breakfast very early in the morning, I usually don't eat bfast until 10ish and my appointment was before then. They gave me the drink to have before hand and I thought I'd be ok drinking it but wow was I wrong. I got the shakes and felt so queasy. I got myself to the doctor as soon as I could. Upon arriving the nurse asked when did I last eat and I told her the night before and she promptly freaked out. She goes " you were supposed to eat this morning!!!" Well no one told me that and she told me the results can be screwed now. I'm like whatever the doctor told me to do what I normally do and I did so there. I don't get my results until next week. I'm assuming if something were terribly wrong or I had to retest they would've told me already.

DeeGreer · July 2015

I have mine at 8am and my doctor said to eat like I normally would. They don't want me going in there hangry, I get psychotic and stabby ! I will faint if I have to fast for 8-10 hours and the drink a pint of sugar. Blegh! I'm ready to get it over with!

gerbies · July 2015

I fasted and barely passed (132 vs. my doctor's cutoff at 135). Pri will likely ask my doctor to retest in a few weeks just to make sure since I was so close to the limit. I am z49, overweight and generally high-risk, so .i just want to make sure.

naka92 · July 2015

I didnt fast and I passed (110 vs 135 cutoff). I just ate my normal breakfast, which is some cereal and juice

binzer33@hotmail.com · July 2015

My instructions from doc
We're not to fast. But to have protein bfast and avoid anything sugary before.

anorthro · July 2015

I didn't fast. Had a protein rich breakfast two hours before my test and then just water for the next two hours. Levels were around 70.

margies2010 · July 2015

I was instructed to fast this time and 4 years ago with DS. I passed last time and failed this time.

DeeGreer · July 2015

Well the drink I got at my doctors office this morning was a clear lime drink. It was like drinking syrup to me...I exclusively drink water and tea. I felt kinda jittery from the sugar rush but nothing crazy like puking or shaking. I think the worst part was the phlebotomist infiltrating my vein. Wtf. She removed the rubber band before she was done getting blood and squeezed the shit out of my arm and the needle went through my vein. I look like I got beat. Thanks, lady! :-w

Knottie16288692 · July 2015

Mine is first thing in the morning Friday. I was told to fast. They even debated on letting me take my meds before the test.

jcole14 · July 2015

I was told to fast for 2 hours before the test and that's not eating, drinking, chewing gum, or anything.. I take my test next week..

JAM910 · July 2015

I just did my glucose test and I did not have to fast. They did recommend not consuming anything too sweet before the test.

leighann1 · July 2015

So I'm pretty sure the conclusion to the original question is:

LiveNLove44 · July 2015

When I was unable to post for the last couple days, I kept wanting to post this:

https://americanpregnancy.org/prenatal-testing/glucose-tolerence-test/

You shouldn't need to fast. There is also a lot of science to support why you shouldn't fast. You have a much greater risk of getting a false positive if you: fast or eat a carbohydrate-rich food (not just sweet) before the test.

Many doctors still recommend fasting because many patients still don't understand the difference between carbohydrates and sweetness in a food. For instance, a cinnamon-raisin bagel, both sweet and carbohydrate-rich, carries an average of 58-60 g of carbohydrate (depending on the size). The glucose drink is 50g. If you eat that before you go to the appointment because that's how you "eat normally," you will most likely get a false positive because you're demanding that your body process 110g of carbohydrate for that test rather than just 50.

If you eat a protein/fat-rich breakfast and minimize carbohydrate intake, you are doing a couple things. First, the body processes both protein and fat more slowly than it does carbohydrate. This also manages to temper a blood sugar spike when you eat more carbohydrate (or drink a glucose beverage). In order to increase the validity and reliability of the test, it would take a bit more patient education leading up to the test. It's easier for doctors to say, "Fast for a couple hours" or "eat normally." If you have a false positive, it's not skin off their back. It is, however, more time for you.

carls1992 · July 2015

My midwife told me to eat protein two hours before the test and then nothing until after. She also warned me to have something high in sugar to eat afterwards
