Choosing a blood sugar meter to use for your diabetes care may be difficult, because there are many on the market. You'll find that it's not really the meters that are expensive, but the test strips you need. If you're considering a low-cost variety, however, check with your doctor first to be sure it will be adequate and safe for your needs.
Good diabetes care means enlisting the help of an experience endocrinologist as soon as you can after getting your diagnosis. It won't be cheap, but your insurance should cover it. Given their training, endocrinologists have a better understanding of your problems than most doctors.
