Hi Evelyn.
As aT2 it depends what you really want to know ?
Checking your blood sugar levels is another part of your diabetes treatment plan. It lets you know how well the other parts of your treatment plan are working, and it's the only way to know how you are doing with your diabetes control on a daily basis.
Your diabetes health care team will let you know what your blood sugar levels should be and how often to check them each day. In general, people with type 2 diabetes should test blood sugar levels with a blood glucose meter at least twice a day, but you may need to test more frequently if you are taking insulin, have just been diagnosed with diabetes, or you are having difficulties keeping your blood sugar under control.
A blood glucose meter tells you what your blood sugar level is at the moment you test. Your doctor may also send you for another type of blood sugar test that tells you how your blood sugar levels have been for the few months before the test.
