Try not to eat at least 4 hours before. And no sugar the day of. Also, drink lots of water before! I had 1.5 liters before the test. I had the orange flavor and it tasted like Fanta
I had the one hour test. I ate a heavy breakfast 2 hours before the test because I was extremely hungry that morning. It was high in fiber and fat, low in carbs. Drank the orange liquid pretty quick. Luckily, I wasn't nauseous, and results came normal. I think eating is fine as long it's not sugary or high in carbs, that is what the nurse had recommended
Definitely don’t freak out, you’ll be fine. I recommend eating & drinking water (no sugar) ahead of time bc after you do the drink you can’t eat or drink until after the blood draw. Take the full 5 mins to drink the drink i chose orange, it’s not fun but it wasn’t as bad as i thought it would be.
I was told if I needed to I could have a high protein snack beforehand like an egg, but to ideally fast for the blood test. I scheduled my blood work early in the morning so I just ate a late breakfast after my blood was drawn. The drink did give me heartburn but didn't make me nauseous. You'll be fine whether you "pass or fail" the test. It is much better to get an accurate reading and treat gestational diabetes appropriately than to have "tricked" the test and not know. Follow whatever guidelines given to you by your doctor to prepare for the test.
Take the whole 5 minutes to drink it, the faster i drink the sicker i would get. I just had my 3hr one and only took 3 instead of the 5 and I got to sit there sick for 3hrs
