When your blood sugar dips too low, it is known as hypoglycemia. When your blood sugar rises too high, it is known as hyperglycemia. Both of these can cause symptoms and serious problems within the human body. A normal range for morning blood sugar levels is 70 to 100 milligrams per deciliter (mg/dL). This is known as a fasting level, since the person has not yet eaten. Once you do eat, normal blood sugar will rise to a level not exceeding 140 mg/dL.
