May have a problem?

I'm seventeen years old and I think I may have a problem. I constantly feel tired, dizzy, and a stomach ache. I noticed if I eat sugar based products (chocolate, candy, cereal, etc.) I feel fine. Blood sugar problem? Potential diabetic? Anything would be helpful.May have a problem?
Hi. I have borderline Glycemia. It is not really that big of a deal if you watch your diet. It is when you get too much sugar in your bloodstream. I would go to your doctor and have them test you for it. What they do is give you this drink (gross tasting really) that has alot of sugar in it. Then they take a blood test to see your levels. Then your doctor will tell you the best route to go with your diet. I hope this helps you.
go see a doctor
you might be hypoglicemic i think that is the spelling its is the opposite of diabetes kinda usually diabetics have higher bloodsugars ck with your dr and get tested by bother, are you eating properly that also might have something to do with it
