Dizziness and Black outs

I've been getting really dizzy on and off, and pretty much every time I drive.  I also will be sitting there sometimes and feel like I'm about to pass out.  I have hypoglycemia and have been tested several times for diabetes, and turned out negative.  I've been testing myself everytime I feel that way and it's normal.  What should I do?

Hello Veronica1973,
You should get your blood pressure levele checked.The dizziness could be due to fluctuations in the bloos pressure,diseases of inner ear,allergies,migraine,cervical spondylosis and many other reasons.Consume lots of water and fresh fruits,maintain your sugar levels,do not be empty stomach for long time.You should consult a neurologist and get the condition diagnosed for appropriate treatment.
