2 hour Glucose Test
Didn't do diet beforehand?

I was wondering whether there was anyone else out there that has been required to do the 2 hour (or 75gm) glucose testing and whether you were advised about the 3 day diet to do beforehand?

I turned up to the hospital to have this test this morning (with Toddler in tow!) and the lady said, "so you've followed the 3 day diet" and I said - no, I wasn't aware I needed to. My midwife gave me the paperwork at my last appointment but never mentioned anything about the need to stick to a specific diet.. just the need to fast prior to the tests.

The nurse still did the testing - but mentioned it could be a complete waste of time if I didn't have enough carbohydrates in my system - I'm hoping the two hours spent there this morning wasn't a waste of time! Has anyone had similar experience?

Thanks

The newer guidelines say that there is no need to follow a diet, you just need to fast beforehand.

I did the GTT, and was only advised to follow the fast, not any specific diet.
BTW, I felt like a truck had run over me for the rest of the day, my poor body was working hard on that glucose, but results came back fine.

Good luck with your test results.

I didn't do the diet before mine, but the pathology place said I didn't need to, and that I just needed to fast from 9pm the day before. Usually the pathology place at the hospital will give instructions when you book the appointment for the 2 hour test.

I have done it 3 times, fasting only, no need for high carb diet ahead of time.
Reliable results, i had GD twice, but my post pregnancy GTT showed i no longer had diabetes.

Another who only needed to fast.  Good luck for it - while I didn't find the sugary drink too bad initially by the end of the two hours I was feeling very poorly.  Hope all goes well original.gif

I did the GTT a couple of days ago - no fasting required.

Sorry to hijack but I have another question relating to the GTT - the lady taking the test started the first one hour timer after she'd taken the blood from the first test - not when I'd finished the drink which was probably about 10 minutes later. Is this the correct way to do it? I was under the impression that the clock was to be started at the end of the drink but I could be wrong.

ETA - oops, meant to say I did fast from 9pm the night before but didn't do the special diet.

I didn't have to do a special diet... and I have GD.

I've done the GTT 3 times in my life now and never have I had to do a special diet. No idea what the nurse was going on about...

I did te 2hr test and there was no 'special diet'. Just fasting beforehand.

I am so glad you posted! My OB and his midwife told me a total of three times to ensure I ate breakfast like normal, go to path, drink the drink (maybe have a blood test dont remember) go to my appt with my OB (which is a check up) and then go back and have the test. I keep hearing about these fasts and getting worried.
Sorry I can't help you with your other question.

There is a 50g glucose challenge test and a 75g glucose tolerance test.

You have to fast for the 75g, and I might be wrong but I think you have to follow the 3 day diet for this one. This is the 2 hour one.

You don't have to fast for the 50g test and it's the 1hour one.

If high risk, previous GDM or you've failed the 50g test, your OB will send you for the 75g test. Otherwise, you just have the 50g one at 28weeks.

Correct me if I'm wrong.

The new guidelines say that everyone should have the 75g test, but most midwives and obstetricians have not yet adopted these changes.

Nope, I've done the one-hour GCT with no fasting or diet (and failed, this was a few years ago.)

I've done the 2-hour, GTT three times. Fasting, but no special 3-day carb loading diet required. First time I did it was 2010.

I'm very surprised (shocked! even) that someone would tell PPs to have your breakfast as normal and then go and do the test. Because then the 1st blood they take isn't fasting blood. Many women (like me!) actually have fine post-prandial levels, but it's overnight that their blood sugar levels go haywire, and you can only detect this from blood taken after a fast....

hi,

i didn't follow the diet, as it was really heavy on carbs, more than i was eating, so i just stuck to my normal diet as that was what i was going to continue with anyway. i fasted and results came back fine.

i think as long as what you ate the last couple of days was normal for you, the results should be reliable.

Thanks for all your replies. I have since googled what the 'diet' recommends and it's not too dissimilar to what I'd normally eat.
I was told this time round they wanted to do the 75 gr test as my mum is a diabetic and my first child was over 4 kgs. I was just a little annoyed they didn't mention the diet requirement when I made the booking (if it is so important ) but I'm sure it will all work out ok.
Thanks again for your responses, it has made me feel much better! I have a midwife appt on Friday so I might just see what the midwife says about the diet requirement, I think she'll say it isn't needed anyway but would be good to have consistency in the comms across the pathology/drs etc re the tests so there are no surprises when you rock up for appointments!

Me too....

I have heard of the diet but don't know anyone who has done it, or why it's called for.

I think the guidelines have changed a bit. First pregnancy in 2008 I failed the 1 hour GCT and had to do the full 2 hour GTT. With this one I was told to fast from 9pm the night before and follow a 3 day diet (basically carb loading before hand).

I recently failed the 1 hour GCT in this pregnancy and again had to do the 2 hour GTT. This time I was told to fast from 9pm as I was previously, but no diet this time around. I even asked specificially on the phone and she said no need, just to fast.

I did the 2 hour test 3 times - once before falling pregnant and twice while pregnant. Was never instructed to do a specific 3 day diet, even though I'd heard of it. Was only instructed to fast once. Second time I did it straight after having breakfast of white toast and lemonade :/

Every time my result was the same, blood sugar was fine.
