In the early 90s, I was diagnosed as Extreme Reactive Hypogycemic. Current medical professionals don't seem to know what that term means. I was almost killed recently while in the hospital, because they thought it was regular hypoglycemia and drew blood without giving me anything to eat or drink. I need to find out the current, correct medical term for my condition so that this won't happen again.
My symptoms: If I don't eat for a long time, my blood sugar drops rapidly and preciptously. Overexertion, stress, heat and dehydration also contribute. Having blood drawn almost always triggers an attack.
First, I get cranky as my brain slows down. Then I cry. Then my brain pretty much stops working and I can't move or talk. At this point, I often get cold and pale (sometimes even bluish or purplish). If I still don't get food, I pass out.
If, before I pass out, I'm given nothing but sugars, my glucose rapidly spikes, then rapidly drops down lower than it was before. I have to have proteins with the sugar to keep this from happening. I don't have diabetes, but when I was given a glucose tolerance test (which almost killed me), I was told that the next time I pass out, I may go into a diabetic coma. (I don't really understand how that works.)
Fortunately, I have a very good diet and exercise regime, and I rarely had episodes. Unfortunately, I recently had an accident, which seems to have weakened me. Especially after my treatment in the hospital, I'm now much more likely to have an attack.
I also have Crohn's Disease. I've been told that the same gene is involved in Crohn's as in blood sugar conditions, which is why I mention it.
