BLOOD GLUCOSE TESTING

CHECKING YOUR BLOOD SUGAR LEVELS

Every person with diabetes should have a Glucometer.  This is a device you use to test your blood sugar (glucose) levels at home.  It’s important to know whether your blood sugar levels are within target to know if your diabetes is well controlled. 

 

Exercise, medication and food intake have an impact on your blood sugar level.  You can determine the impact by testing your blood glucose level.  It is important to keep good record of our readings – either in a small book or use the in-built memory function on your glucometer.  This will your diabetes care team make treatment changes if necessary.
