Personal glucose monitor -

The development of CGM devices that can frequently and easily monitor blood sugar levels without finger sticks has revolutionized care for millions of people with diabetes.

Besides providing results of blood sugar levels, some devices have alarm settings that alert the user, or other people, if blood sugar becomes dangerously low or high. And some systems can transmit results directly to the user's doctor, if desired. So, why would a person who doesn't have diabetes want to monitor their blood sugar?

Possible reasons include. But truly, knowledge that is useless, redundant, or inaccurate doesn't make you powerful! It may even be harmful. For example, if biologically insignificant drops in blood sugar lead you to snack more "to avoid hypoglycemia" , you could gain weight and actually increase your risk of developing diabetes.

If the monitoring system sometimes provides inaccurate information or false alarms, unnecessary anxiety, calls or visits to the doctor, visits to an emergency room, and even inappropriate treatment may follow. Unfortunately, some makers of CGM systems aren't waiting for solid research results to market these devices to healthy people.

So, consumers and marketing professionals — not researchers or doctors — may wind up driving demand for the product. For any new technology there's a scientific learning curve to figure out when to use it.

In my view, we're at the very beginning of the learning curve for home monitoring of blood sugar in people without diabetes. Before buying into what may be the next fad in health monitoring, I think we need to learn a lot more. There is wisdom in the teachings of one of my favorite professors in medical school: "Just because you can measure something doesn't mean you should.

If you don't have diabetes, should you monitor your blood sugar? Where's the health benefit in this? Blood sugar monitoring for people with diabetes offers undeniable health benefits For people with diabetes, a major goal of therapy is to keep the blood sugar close to the normal range.

If knowledge is power, why not monitor your blood sugar? Possible reasons include Detecting prediabetes. In prediabetes blood sugar is slightly high, but not high enough to meet the definition of diabetes. For healthy people, blood sugar testing is typically recommended every three years or so; if prediabetes is diagnosed, repeat testing is recommended more often, at least yearly.

CGM might allow earlier diagnosis of prediabetes or diabetes. This could be particularly helpful for people at higher risk for diabetes due to family history or other factors, and people taking medicines that can raise blood sugar.

The notion of "optimizing" blood sugar for peak mental or physical performance. Not surprisingly, some CGM makers suggest knowing your blood sugar can help you make changes to keep it in an "ideal range" that will help you perform your best, prevent diabetes, or improve health in some other way.

For example, you might change what or when you eat. None of these marketing notions has been proven, or even well studied.
