Managing your diabetes requires a continual balance of insulin, food, and exercise. When these are out of balance, your blood glucose (BG), or blood sugar, can go very high or low.

Very high BG (hyperglycemiaBG (Blood Glucose) above 250 mg/dl) or low BG (hypoglycemiaBG (Blood Glucose) below 70 mg/dl) can interfere with your thinking, reaction time and judgment. These can disrupt your ability to drive and can increase your risk of being in a collision or getting a ticket.
