can you be hypoglycemic without being diabetic?

I have had conflicting answers from two doctors. here 's the situation: One doctor sent me for a glucose tolerence test where my blod sugar crashed to a 55 before they ended the test. I was diagnosed as a reactive hypoglycemic. my doctor sent me to an endocrinologist who had me stay in his office for 12 hours and get my blood drawn every hour. I did not have a sugary drink with him and my blood sugar dropped only 2 points.He told me that I did not have low blood sugar. I have also read online (I know its not the most valuble source of info), that some doctors do not believe that reactive hypoglycemia exists. Can anyone help me unravel this? Does it exist?
I appreciate the answers and I do want to say that both grandfathers have adult onset diabetes and my dad is a pre-diabetic.

It is controversial. When i was working we were taught that yes it does exist without being diabetic.
Many of the younger endocrinologists do not believe that it can occur unless you are diabetic.
If I was you I would stay with my family Dr. and follow his advice and his suggestions on what to do when your blood sugar develops.
He may want to send you to a dietitian for a better diet and how to deal with the symptoms you develop. Good Luck sweetie.

what i understand of it, and i've met people like this, is that you're over producing insulin. which means that right now, your sugars are low, but after a while your poor lil overworked pancreas will kick out and quit producing at all. just drawing out the process of getting diabetes i think. i bet it's still reversible now...take it from all of us...reverse it if you can!
