I am 42 and battling what I think is hyperinsulinism.  I have constant hypoglycemia.  I weigh 130.  I cannot seem to eat carbs almost at all without having horrible episodes.  My bloodsugars lowest (recorded) was 30 and that was after food to try to bring it up.  My doctor thought I had MS at one point because of Many spots on my brain. (No MS symptoms) After reading all this for several years I think the "spots" are just from the extreme effects of my blood sugar.

Summarized question: How to confirm hyperinsulinism?
