Slightly scared, anyone else experience this?

So before I was pregnant, I had several times where I got hot flashes and felt as if I was going to pass out.  My gyn thought it was due to hormones, they I got pregnant and the episodes continued and have gotten worse.  My ob said due to increased blood flow...even though I reminded her it was happening before pregnancy. 
They just sent me for my glucose 1 hour test and my sugar bottomed out at 42 and I wasn't even fasting!  Now they say I am hypoglycemic and probabaly due to my rny.  I have an appointment soon with a high risk ob and nutritionist and so on.  Any one else have this happen to them or know anything about it?
I got pregnant by surprise at 6 months post op...fyi.

Thanks for any help!

 Hypoglycemia is VERY common amongst RNY patients.  I have it as well.  I keep it under control by eating a well balanced meal and making sure I eat often.

Also, I keep hard candy in my purse just in case it starts to drop.   

I would experience the same hot flashes/cold sweats, etc you experienced both before and after I got preggo.  I mentioned it to my regular dr prior to even trying to get preggo.  I knew it was my sugar because if I ate something (with sugar, etc) in it I would come back out of it.  I just started last week with the nutr in regards to my diet and I test my blood sugars three times a day.  I go back in two weeks and we will see how it's going.  The meal plan they set for me is very reasonable, and mostly what I was already eating.  It is difficult at times to get in all the food they want me to (esp at dinner and right before bed); but I am working on different items from the list every day trying to get it all in.  So hopefully yours will be simple like mine....Good luck!  Stacey
