Why test your blood sugar?

Blood sugar testing — or self-monitoring blood glucose — provides useful information for diabetes management. It can help you:

  • Judge how well you’re reaching overall treatment goals

  • Understand how diet and exercise affect blood sugar levels

  • Understand how other factors, such as illness or stress, affect blood sugar levels

  • Monitor the effect of diabetes medications on blood sugar levels

  • Identify blood sugar levels that are high or low
