You can monitor your blood sugar at home with one of a variety of devices that use a small sample of blood.

Hypoglycemia is most often seen as a complication of diabetes and is sometimes referred to as "insulin reaction."

The purpose of blood sugar is to provide "food" for your body's cells. Glucose is the sugar that provides energy all cells in your body need.

The official term for blood sugar is glucose, and having either too little or too much of it occupies the minds of people with diabetes daily -- even hourly. But keeping blood sugar at safe levels can be achieved by most patients through monitoring, diet, exercise and drug therapy.

In adults, a screening blood sugar test is generally used to determine if your blood sugar is too high. For adults, having an elevated blood sugar usually will not give you symptoms and may indicate a pending or current problem with type 2 diabetes.

Many people with diabetes who use insulin test their glucose two to four times daily. By tracking changes in the readings, you can tell when your blood glucose goes up or down.
