Diabetes cares and frequency of blood glucose monitoring varies from person to person. People diagnosed with type 2 diabetes should consult with both their doctor and their diabetes educator to determine a monitoring schedule that works for their individual situation. Blood glucose levels are often tested at specific times.
Post and pre-prandial blood glucose readings are good predictors for overall glycemic control. An A1C blood test will show the average blood glucose level over the last 3 months, a measure of how well-controlled it is. Your doctor can tell you what the appropriate blood glucose target ranges are for your individual situation as well as how often testing is recommended. You won't necessarily have to test your glucose levels this often.
More frequent blood glucose readings are useful for people who are recently diagnosed and are just starting diabetes treatment; for those starting medication or who have just adjusted their medication; and for those who are making significant lifestyle changes. Frequent measurements establish a baseline and help to show how dietary choices, exercise, and medication affect blood glucose.
Keep a record of your readings along with notes (download free diabetic log sheets or buy a log book). Records will help show how well your sugar levels are being managed, as well as help pinpoint potential problem areas too. Seeing the numbers together also makes it easier to do a comparison and spot any trends. Once there is a good understanding of how your blood glucose levels are affected by lifestyle choices and medication, how often you monitor can be decreased. Diabetes self-care and the frequency of blood glucose monitoring should be discussed with your health care provider who can advise you best about what's right for you.
