Yeah!! But it depends on many things, not the least of which is your midwife/OB and how they feel about how precise the test needs to be.
It never hurts to ask though. I know lots of mamas who were able to do a less disgusting test because they simply told their OB/etc. that they rarely consumed sugar to begin with.
My midwife is pretty laid back about it. She said I can eat a certain number of jellybeans instead of the glucose drink if I want, OR I can eat or drink anything else that has the same amount of sugar. The jellybeans adds up to 50g of sugar. So if I find something that has 50g of sugar, that'll work. She said she didn't care what form of sugar it was, either.
So I'm drinking one and a half organic Blue Sky ginger ales for my test.
I have learned that apparently the liquid sugars are processed faster or easier or something than the food-based ones. Not sure how that impacts the test results, but I figure since the original test is a drink, I'll stick with a drink form (plus it's easier for me to drink a big ginger ale than eat 27 jellybeans in one sitting -- blech).
The only thing I've been warned about is to avoid ingesting any OTHER sugars before or along with the ginger ale (or whatever chosen 50g of sugar), because that can mess the results up. So I'm planning to eat some hard boiled eggs or something (just protein) beforehand.
Last pregnancy I tried the jelly beans and just couldn't do it (I only managed to eat a few), so I ended up declining the test altogether, and my m/w was fine with it. I was a little younger, in good health, didn't eat a lot of sweets, and wasn't spilling sugar in my urine at all. This time I've gained more weight than before, am older, and figure I don't mind drinking ginger ale.
My midwife is really wanting me to take the test, but is trying to make it as palatable as possible for me. I think that's awesome.
There are a couple different tests, and some require fasting beforehand (I think though that you should still be able to consume protein -- just no sugar).
I think it's awesome that your NP let you do a more palatable test. I can't imagine drinking that nasty orange goo, or eating a ton of candy (and I actually like candy! But not that much -- not at once).
