Glucose Screening Test - What Should I Eat All Day?

Updated on November 04, 2010
A.K. asks from Minneapolis, MN
23 answers

Now that I'm 25 weeks pregnant, I have to take the glucose screening test. My doc said I do not have to fast. I will take the sugar solution at 2:45 and test an hour later. Any suggestions of what NOT to eat today for breakfast and lunch? Or what TO eat? I don't want to skew the results the wrong way. I am a little nervous since I have been eating a bit more chocolate lately because of the darn halloween treats everywhere.
Thanks!

What can I do next?

You are to just to eat like you do everyday. The reults will not be changed based on what you eat. OB 1 hr. glucose is different than a person getting screened for a regular diabetic screening. The paper they gave you should outline this. The orange flavor taste better than the lemon lime BTW.... You will be fine. Congrats on baby.

Wow, I'm surprised that they have you doing the test in the middle of the day. When I took it, I was instructed to go first thing in the morning with NOTHING in my stomach. I did my best to eat salads and cut back on candy for the 2 days before the test, but I still failed it and had to go back for the long test - just to find out that I didn't have gestational diabetes. Most of my friends failed it the first time and had to go back for the long test; and none of them ended up with gestational diabetes.
Hopefully you will pass it the first time - good luck!

Wow -you're lucky! I was always told I had to fast! I would stay away from sweets and white carbs -white bread, white rice, white pasta, etc. Some lean protein and veggies should work for you. If you want fruit or fruit juice, I would eat it in the morning instead of near the testing time.

One note -how do you feel these days? If you're having "episodes" where you're feeling shaky, like you're going to faint, etc. you need to tell your doctor because your blood sugar may be getting out of whack -even if you don't have gestational diabetes. Believe me, I understand the pull of sweets, especially when pregnant, but be careful with them if you're having symptoms.

You need to eat normally...whatever you would usually put in your mouth, and that includes the junk food if that is what you would do. This test is trying to determine whether or not you are going to present with Gestational Diabetes now or later on during the pregnancy. Your body has got to be able to handle utilizing glucose and regulating insulin levels in the body while you are pregnant. That needs to happen on an everyday basis and it needs to regulate it no matter what you are eating. Don't try to eat a specific diet just because your are having a Glucose Tolerance Test. It can and will skew the true results. Eat what you normally would and let the chips fall where they may. You might end up passing with flying colors or like myself, I failed the Glucose screening test and got sent for a 3-hour Glucose Tolerance test a week later. I passed that one by the hair on my chinny-chin-chin. I was not diagnosed with Gestational Diabetes but my body does run borderline high sugars when I'm pregnant...it's just what my body does and it's a fact for me. You'd rather know the truth about a test and remain healthy throughout the pregnancy than try to control results that may not have accurate results.....thus hiding or "masking" a condition that will not be treated and handled properly. Eat normally and let the good times roll. You'll eaither pass it the first time or be sent for the long glucose test and pass that more than likely. Either way, you'll at least know what your body is doing. Good Luck and I hope you pass the first time through. If not...no biggie...you will be fine!

The whole point of the test is to see if your blood sugar can regulate with your usual diet that you regularly eat. Trying to cut your sugar out completely will only give you false results and could wind up being dangerous to you later on. It shouldn't be difficult to pass it. (I took it twice and passed and I'm a sugar fiend!)

answers from Columbus on

You are supposed to eat a normal meal with carbs, veggies/meats or whatever your usual diet is. Try avoiding overly sugary items - for instance, syrup on your waffles but having some sugar in your coffee or juice is absolutely fine. You need to find out how well your body absorbs and breaks down sugar in a normal setting because gestational diabetes is something that needs to be diagnosed and watched closely.
Don't be disheartened if it comes back positive - false positives are very common with this test. I needed to go through the 3 hour tolerance test because my screening came back positive but I passed the 3 hour test. The 3 hour test can be a pain to go through but it is worth it to rule it out.

They want you to eat what you normally would so they can get a accurate blood sugar. Maybe keep the chocolate out of your diet for the day. The drink is like a orange soda and the whole thing is pretty painless.

When it was my time to the glucose test, i ate regularly so then you can tell what you have to cut out if your sugars are high etc. I wouldnt change what I ate for the day for the test. Good Luck....its discusting.

When I did mine it was also after lunch and they told me to eat normally, but as the nurse said, "Well, don't walk in here drinking a large pop or something." So just make sure you don't binge on sugar right before because that could make the difference in a few points that might make you have to do the 3 hr test. Otherwise a little candy (especially the day or two before) is probably fine.

waiting to eat until after the test is absurd to expect a pregnant woman to do. i for example would get light headed, nauseous, and grumpy if i went too long without eating. i am hypoglycemic, but it seemed amplified while i was pregnant. i read through some of the answers where they say to eat regularly, or to eat certain foods and not others & i personally think these are terrific suggestions. but going over half the day without food- that's just nonsense.

Nothing too sugary the day of your blood work. Nothing at all two hours before you drink the solution. I just took my test last week and these were my instructions.

Stick to eggs. no sugar at all straight protein. No carbs because they turn into sugar and of course sugar is sugar. I went in like having ate the first time and when they did the first poke they sent me packing. They said in there experience if it was over some amount, i can't remember it was, more likely I'd fail.

So I drank water and ate eggs and I was at 70 something. They were pleased and I took the test and passed with flying colors. So I'd go with eggs and water. Straight protein so filling and no problems.

There are two types of tests - the one that you are having done where they tell you to eat normally, then if that comes back high they do the one where you fast over night and they do a three hour test in the morning where they test your levels several times.

My first test came in only 3 points high so I had to do the 3 hour test (which was perfectly normal). One of the nurses told me that if I had done the first test in the morning instead of after lunch, it would've been normal(!) and I wouldn't have had to go through the really ugly(!) long test.

If I had to do it over, I would only take an appt in the morning and I would've only eaten protein before going.

I wouldn't have anything sugary today. I had an iced tea right before mine with my middle child and my numbers were high. I had to go back for the three hour testing and it was torture just to find out nothing was wrong!!

Just have some toast or something to hold you over.

So strange. I always had to fast before my tests and then once I took them, I was encouraged to eat a high protien meal after to counter the glucose.
That would be my suggestion for post glucose screen is the high protien meal.

answers from Lincoln on

Eat what you normally eat. If you want, you could not eat chocolate the day of the test. Avoiding a huge sugary meal might be a good idea (unless that is your normal food). The reason they have you drink or eat a sugary substance and then test after a specified time, is to see how fast your body metabolizes sugar. There is no special diet that will speed this up or slow this down in one day.
I suppose you could skew the results by eating a very high sugar or carb lunch and testing shortly afterwards.
I am not an expert however as I understand it, the body processes food in this order:
1. Carbohydrates (sugars are included in this one).
2. Proteins.
3. Fats.
It takes about 3 hours for the body to metabolize the average meal. If you eat lunch no later than 12:30, you should have already metabolized the sugars from that meal.
Basically, unless you spend the entire day eating candy or otherwise packing sugar into your system, you should not have a problem. I suggest you eat good healthy foods and not worry too much about skewing the test.

answers from Atlanta on

Youre not trying to skew the results. A good meal that is a low sugar meal would be a small portion of meat (6 oz), green vegetables and maybe a complex carb like red potatoes or a baked sweet potato. Simple carbs turn to sugar immediately. Complex carbs change slowly and usually don't upset your blood sugar. Green vegetables are healing as well.

If you are having any issue, go to myhealingkitchen.com and look at the recipes. My husband's type 2 diabetes is completely under control and I know of some insulin dependent Type 1 diabetics that have come off of insulin because of the 30 day diabetes healing diet. Halle Berry being one of them.

PS Dark chocolate will little sugar is actually a great antioxidant and good for you. I couldn't live without it!

I wouldn't eat lunch right beforehand. For my first pregnancy, I ate regularly and had to go back for the longer test. The second time, I made sure I didn't eat close to the test and was the first test was fine.
