What's different about this ad, you wonder? The jogger doesn't have diabetes. So, how does his phone know his blood sugar? And why, in the middle of a run, does he want to know the result? Read on. Several companies are working hard to make this sort of ad a reality, as they begin marketing implantable blood sugar measuring devices to people without diabetes.
Called continuous glucose monitoring systems , or CGMs, they are often used by people who do have diabetes. These companies could reap enormous profits by convincing healthy people to start monitoring blood sugar. Already, many of us monitor our weight, heart rate, or steps per day.
CGMs use tiny sensor wires, or filaments, that pierce the skin to frequently and easily assess blood sugar levels. The filaments remain in place, usually on the upper arm or abdomen, protected by an adhesive patch.
Results are displayed on a receiver or transmitted to the user's phone. Is there any evidence of benefit if people without diabetes monitor their blood sugar levels with CGMs?
There's little published research to help answer this question. In fact, many of the abnormal levels were considered implausible or a mistake. Another small study looked at sedentary individuals without diabetes who were overweight or obese.
Participants completed a counseling session about the effects of physical activity on blood sugar and used a CGM device and an activity tracker for 10 days. Afterward, they reported feeling more motivated to exercise. But I could find no published study suggesting that monitoring translates into improved health.
Well, wait: one maker of a CGM device posted a study on its website reporting better blood sugar results among healthy people using their product. However, the study wasn't published in a peer-reviewed medical journal, it lacked details that would allow critical evaluation, and it examined what seem to be arbitrary ranges of blood sugar values, not actual health outcomes such as heart disease, nerve damage, or hospitalizations.
So, until more studies prove the value of CGM for people without diabetes, we won't know whether the cost and time it takes to implant one of these systems is accomplishing anything, or is just the latest health monitoring fad wasting effort and money.
Speaking of cost, CGMs aren't cheap: they can cost several thousand dollars a year. And it's highly unlikely that health insurers will cover CGMs for people without diabetes, at least until there is compelling evidence that they're actually helpful.
For people with diabetes, a major goal of therapy is to keep the blood sugar close to the normal range. This helps to prevent symptoms and complications, prolong life, and improve quality of life. 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.
I selected four CGMs that are widely available, reasonably priced, easily applied, and use a smart phone as a transmitter: Abbott FreeStyle Libre 2 , Abbott FreeStyle Libre 3 , Dexcom G-7 , and Nutrisense. Therefore, those using finger stick glucose to check CGM readings may find discrepancies in readings when blood glucose is rapidly changing.
Ease of administration: All four CGMs were easily affixed to the back of my arm using a plunger device held against the skin. I engaged the help of my mechanical-engineering husband, who found administration straightforward.
All four sensors have a short monofilament that remains embedded in the skin. Event Tracking: All four allow tracking of food and exercise in the companion app and include a notes feature to track meal details and other important factors, like stress and sleep. Event tracking is critical for diagnosing what led to spikes, dips, or blood sugar variability, since individuals react to foods differently.
Summary Reports: All four provide summary graphs that are useful for monitoring glucose range and trends, along with user-supplied notes. Daily reports that show actual blood glucose graphs, along with meals and notes about food, exercise, and stress, are very helpful for determining what behaviors and situations impact blood glucose.
Water resistance: The FreeStyle Libre sensors are water resistant and work as long as they are not submerged more than 3 feet or kept underwater for over 30 minutes at a time.
The Dexcom G7 is waterproof and may be submerged under 8 feet of water for up to 24 hours. I showered and worked out with all four CGMs without any issue. Support: All four systems provided user videos, phone support, and explanations about app functionality.
Cost: Cash prices vary widely, so be sure to compare prices. I took advantage of substantial savings by checking prices and using online prescription discount services.
Sensor prices are included below. The Abbott FreeStyle Libre 2 offers the best bang for your buck. It was easy to provide my health care provider with access to my data through the app and simple to download reports to email.
The sensor remained securely attached for the day period. In fact, it was a bit difficult to remove, and the adhesive circle remained so long that I wondered if my showering habits were subpar.
I later learned that my concern was unfounded and that my graph would fully populate as long as I scanned my arm at least every eight hours. The Dexcom G-7 provided real-time continuous data without my having to scan the sensor, a huge plus for me.
In addition, the Dexcom G-7 provided detailed reports that were easy to download and share, as well as quick weekend technical help. Ten days of coverage is a bit disappointing compared to 14 days for the other three products. My sensor became loose on the ninth day, but there was no residue to scrub off.
The FreeStyle Libre 3 had all the advantages of the Libre 2 shareable data, great reports, helpful support , plus several additional features.

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. And guess what — even the ideal blood sugar range for a person who isn't diabetic is uncertain. The illusion of control. Having more information about your body may provide you with a sense of control over your health, even if you take no immediate action.
Let's face it, it's tempting to gather information about our bodies that might be interesting even when we're not sure what to do with it. The bottom line Unfortunately, some makers of CGM systems aren't waiting for solid research results to market these devices to healthy people.

CGMs provide significant, potentially life changing benefits for diabetes management. CGMs are recommended for several reasons because they:.
People with type 1 and type 2 diabetes who use a CGM have fewer instances of hypoglycemia and a lower A1C. One obstacle with CGMs is the cost of access to diabetes technology. Many people with diabetes who have put off getting an insulin pump or CGM, do so because they are too expensive.
Another major obstacle is due to strict Medicaid coverage policies they are not accessible for people who need them. In fact, people with diabetes on Medicaid, especially in minority communities who use Medicaid, are the least likely to use a CGM.
This is concerning since people with diabetes are more than twice as likely to receive their health care from Medicaid as those without diabetes. Individuals who meet the coverage criteria listed in the FAQs below for a CGM and want to learn more about them should talk to their health care provider to ensure it is the right tool for the management of their diabetes.
The American Diabetes Association ® ADA released a new study looking at pharmacy and medical benefit claims for CGMs across commercial insurance plans, Medicare and Medicaid and data on age, race, geography, and diabetes prevalence.
The findings show people of lower income and older people of color who live in states with the highest rates of diabetes prevalence and mortality are the least likely to get access to a CGM. ADA is quite concerned about these findings, given the effect of the COVID pandemic on this population and the importance of tools like CGMs in diabetes management.
Learn more by viewing the study PDF. We are partnering with people with diabetes, health care professionals, advocacy groups, and policy makers to address CGM access for those who use Medicaid. We need your help in eliminating these systemic barriers to CGMs! Soon, there will be an opportunity to get involved depending on your state with CGM Medicaid regulations and increased access to this technology.
