The symptoms are pretty much the same from what I've read. I have reason to believe I have reactive hypoglycemia although a fasting glucose test showed my blood sugar to be low but within normal limits. I also have incidents that feel like low blood sugar when I am stressed and overloaded and it doesn't seem to logically correlate to what I have or haven't eaten. For instance, I don't feel hungry like with a growling stomach. So today I had one of those times when it seemed like everyone wanted something from me at once. I walked away from the situation but shortly thereafter my heart started racing, my hands started shaking and I had this weird feeling of unreality. So in order to differentiate between the two I have a question that may help clear it up.
When your blood sugar drops because of reactive hypoglycemia, does it seem to come out of nowhere and happen very quickly?
This is how it happens to me. Ironically, according to what I read online, eating something helps both.
