As a diabetic, it is essential that you test your blood sugar on a daily basis. You can use a blood glucose meter to test your blood. There are several reasons why you should test your blood sugar.

Reasons to test your blood sugar

Using a blood glucose meter to test blood sugar levels takes the guesswork out of daily diabetes care. Here are reasons why you need to test for blood sugar:

  • Able to identify if your blood sugar level is high or low to prevent emergency
  • Able to show high blood sugar levels (High blood sugar is detrimental to your blood vessels, heart and nerves)
  • If taking rapid or slow-acting insulin prior to meals, you need to know how much insulin to take
  • Able to know how lifestyle factors such as exercise, stress, diet, and being sick affects your blood sugar
  • Ability to choose correct first insulin dose and schedule; adjust insulin dosage or schedule as needed

How to properly test blood sugar

Testing your blood sugar levels is as simple as pricking your finger, palm, or forearm with a small needle (called a lancet) to draw blood. Afterwards, you put the test strip in the blood glucose meter to measure blood sugar levels. The measurement results usually come within 1 minute. While some diabetics have qualms about drawing blood, they get adjusted to it pricking after continuous usage.
