Blood sugar levels indicate the amount of sugar or glucose absorbed into the bloodstream. Blood sugar levels that are either too high or too low can cause death. Diabetics and those with certain conditions such as hypoglycemia must maintain their blood sugar levels and monitor them closely. The normal blood sugar range is 70 to 100. A diabetic can have a level of 60 to 120 and still feel fine. A fatally high blood sugar level is anything above 550. It's possible for an adult to reach even higher levels before exhibiting any symptoms or problems. When the level reaches 600, the person develops hyperosmolar syndrome, which can cause diabetic coma and death.
