Checking your blood sugar levels often and writing down the results will tell you how well you are managing your diabetes so you can stay as healthy as possible. The best times to check your blood sugar are before meals and at bedtime. Your blood sugar meter may have computer software to help you track your blood sugar level. This is usually available from the manufacturer’s website.
