Blood Sugar

Frequently monitoring your blood sugar level is important to manage diabetes.
Publications International, Ltd.

Monitoring your blood sugar is a vital part of the diabetes management process, and frequent self-monitoring is the key to successful diabetes care. Testing your blood sugar, also called glucose, allows you to adjust your food, medication, or activity level so that you can keep your blood sugar level within a healthy range.

When blood sugar is too high, it's called hyperglycemia. If blood sugar levels remain too high for too long, there's a greater likelihood of serious short-term and long-term complications that affect the whole body. Low blood sugar, called hypoglycemia, can result in unpleasant symptoms or even dangerous complications.


Tightly controlling blood sugar levels, however, has been shown to prevent, reduce, or even reverse some of the long-term complications associated with diabetes by up to 60 percent. Tight blood sugar control depends on frequent monitoring.

Testing your blood sugar multiple times each day can help you understand blood sugar patterns and fluctuations associated with certain foods or alcohol, specific medication doses, your level of activity, illness, and stressors at home or work. With this information, you can then figure out what works best for you -- food, exercise, medications, or insulin -- to keep your levels as close to normal as possible. If you don't test your blood sugar levels, or test only infrequently, you'll never be sure whether your diabetes is really controlled.
