I have severe hypoglycemia. My "normal" blood sugar rarely gets above 60 and I have had readings as low as 12 before.
The only sure fire way to know if you have hypo is to have the GTT done. It really isn't as bad as you think, and believe me, I have almost non-existent veins when it comes to having blood drawn!

I've had it done twice and while it is far from pleasant, it is very tolerable.
There are 2 types of hypoglycemia - reactive and fasting. Most people have "reactive" hypoglycemia. Reactive generally occurs after meals because your body is producing the insulin needed to keep your body going. However, sometimes, we can produce too much insulin and it breaks down too much sugar, causing the blood sugar to drop off drastically. This is the "low blood sugar" that causes the shakes, fatigue, headache, irritability, anxiety, etc.
Fasting hypoglycemia is typically the result of something called an insulinoma and is a much more serious condition.
Chances are, you blood sugar is reactive - especially if you get the symptoms if it has been a while since you have eaten, if you get them just after meals, if you get them more often if you are eating sweets or carbs, etc. The best way to combat this is to get yourself on a well-balanced meal plan with lots of protein and minimal sugars. Eat frequently throughout the day. My rule of thumb is to not go more than 2 hours without "snacking" on something (I keep peanuts with me constantly!). Try not to make your snacks real high in sugar though. If you start feeling shaky, get something to eat. It doesn't have to be a lot, but again, try to stay away from sugar if at all possible. While the sugar will bring your BS up immediately, if you truly have hypoglycemia, often times, as fast as your BS will come up as a result of the sugar, it will spike back down because you are producing too much insulin for the amount of sugar. Which basically means...the sugar is only a very temporary solution.
I have to monitor my blood sugar daily. I've learned what foods I absolutely can not eat, and what foods I can get away with. One thing that I have learned the hard way...if I am going to eat any sweets at all, it can't be on an empty stomach! I don't know why that makes a difference, but for me, it really does.
I've dealt with this for several years...if you have questions or need to talk, feel free to PM me!
Hope all goes well...and talk to your doctor about getting the GTT done! They can use smaller needles if they need to.
