Can exercise cause low blood sugar in a non-diabetic?


I play racquetball 3 days a week and it is VERY strenuous. The other day about an hour afterward I got dizzy, felt very warm, heart pounding and just felt like something wasn't right.

It then led to blurred vision in 1 eye and confusion. I called my doctor and left work. He's doing some blood work and was going to give me a CT-Scan but hasn't yet.

I forgot to tell him that I hadn't eaten anything before or after playing, which is unusual for me. I only had a can of carrots after playing.

Could this have been hypoglycemia caused by the exercise??

I'm 30 years old in good health and not diabetic. Anyone have this happen to them after a hard workout?? My buddy was trying to tell me I might have had a minor heart attack or stroke?? The doctor took my blood pressure and it was normal by the time I got there.

This could very well have been hypoglycemia. Carrots don't raise my sugar much, despite some claims to a high glycemic index.
