How can low blood sugar cause dizziness?

ANSWER

People with diabetes need to check the amount of sugar (glucose) in their blood often. You can get dizzy if it drops too low. That also can cause hunger, shakiness, sweating, and confusion. Some people without diabetes also have trouble with low blood sugar, but that's rare. A quick fix is to eat or drink something with sugar, like juice or a hard candy.
