Just be sure to talk to your doctor about diabetes monitor options to make a plan for the best health monitoring for you. This meter is recommended by Dr. Nate Favini, medical lead of Forward. Note from Jan. This sensor is smaller than the Libre 2 and has readings sent directly to your smart phone every minute, along with other perks.

Though continuous glucose monitors are more expensive, they can help you understand what types of food and exercise are best for you. To read your blood sugar on the Freestyle Libre, you do a quick scan with the CGM device to get a reading.

There's also optional alarms if your blood sugar gets too high or too low. Rebecca Fenichel, an endocrinologist at Westmed Medical Group , and was previously recommended by Dr.

Josh Emdur, medical director of SteadyMD. The Dexcom G6 doesn't require you to manually scan to get a glucose level reading -- instead you get a wireless reading either on a dedicated receiver device or to your phone or Apple Watch. The Dexcom G6 reads your blood sugar every 5 minutes, keeping track of your blood sugar level as long as you're wearing it night and day.

You can set a custom range for where you'd like your blood sugar to be, and if it goes into low blood sugar or high blood sugar ranges you set, you will get notified. The Dexcom monitor is also approved in pregnancy and offers continuous monitoring that you can see on your phone at all times," Fenichel said.

Note, Jan. This sensor is smaller than the G6 and has an improved alert system, along with a few other differences. The Dexcom G6 is a wireless continuous glucose monitor that sends near constant readings via Bluetooth to a smartphone or watch app.

Its readings are a few minutes behind, but its depth of data is like no finger stick. If you want a device that you can set up and don't have to worry about reinserting for up to days, Eversense is a great option for diabetes management.

A health care provider will insert the sensor, and then you place the transmitter above that. Once the sensor is in place, you don't have to change it out for about days, a long sensor life. The transmitter itself can alert you if your blood sugar is too high or low, and you can also have wireless readings sent to your phone via an app.

You can share your blood glucose data from your app with your doctor or anyone else who wants to check your blood sugar readings.

The Guardian Connect System is a CGM that can tell you your current glucose readings quickly via a connected app and also lets you easily access trends and data about your blood sugar over time.

One feature that stands out with The Guardian is the "predictive" alerts you can get about your sugar. Unlike other CGM systems that alert you when your sugar is already high or low, The Guardian uses technology that predicts when your blood sugar might get high or low, before it happens.

Another feature that comes with the monitor is the Sugar. IQ diabetes assistant app for diabetes management, which uses your data to help you figure out what diet, exercise and insulin works best for you. When choosing continuous glucose monitors for this list, we look at which models were previously recommended by doctors.

We also look to include a CGM that had a longer-lasting sensor life and include models that are popular choices for people with diabetes. While anyone can buy a regular blood glucose meter, you'll need a prescription from your doctor for a CGM system.

Doctors may recommend a continuous blood glucose monitoring device for reasons tied to your unique health circumstances and lifestyle, to track your personal glucose trends and keep on top of your insulin levels, but a CGM device may not work for everyone's unique diabetes care plan.

CGM devices can also give you and your doctor more information about blood sugar levels than a standard meter -- like if your blood sugar begins to drop too low, the device can warn you about your dropping blood glucose levels, "which can be a very helpful feature in helping patients avoid hypoglycemia," Fenichel said.

No, continuous glucose monitors are available only by prescription. You can get a regular glucose monitor without a doctor, however. Many insurance plans, Medicaid or Medicare will cover a continuous glucose monitor, though they may require prior authorization. But the cheapest way to get a continuous glucose monitor is to go through your insurance, Medicaid or Medicare -- you could potentially get one for free.

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.

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.

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.

As with the Libre 2, missing data is populated once the sensor is scanned. The 3-inch-diameter protective cover creates a larger footprint than the other CGMs, but it is easy to apply, stays secure for a day period, and provides additional protection. Blood sugar management can be complex, as many factors come into play stress, sleep, food order, food choice, exercise, etc.

Keep in mind that these modules take time, so this is not a quick fix, but rather an approach for those who want a deeper understanding of blood sugar management. When asked, my nutritionist told me which of my metrics were acceptable and which needed improvement, and they provided suggestions for how to modify my behavior.

With my goals in hand, it was easy to implement simple behavioral changes, like eating protein in the morning, adding eight deep breaths periodically while working, and taking a short walk after a heavy meal.

Levels is an app that uses CGM data to provide users with insights into how their diet affects their health. The app supplies real-time blood glucose level data and syncs with Apple Health kit. As you track your glucose levels, the app will provide daily recommendations for sleep, exercise, and stress management.

Devices that are compatible with the Levels ecosystem include Dexcom G6 and Freestyle Libre. The FreeStyle Libre first debuted on the market in Like other CGMs , it uses interstitial fluids instead of blood to measure blood glucose.

You use the Libre by wearing a sensor on your upper arm. To keep the Libre system working, you have to reapply a new sensor to your arm every 14 days.

One downside to this CGM is that it can be a little confusing to keep track of their latest models that have the same names.

Some users also report inaccurate readings as well as skin irritation from applying the sensors. The Dexcom G6 is a sensor you wear on your abdomen that transmits information to a corresponding app you can download on your phone, tablet, or smartwatch.

Users like the fact that the sensor transmits this data automatically every 5 minutes. What sets the Dexcom G6 apart from other types of CGMs is its ability to complement other devices you might have for your diabetes management. These include insulin pumps. One of the most common complaints is that you have to change out your sensor every 10 days, versus longer wear on other CGM devices.

The manufacturer, Senseonics, a publicly traded company, started experiencing challenges in Senseonics has scaled back its workforce but continues to support the Eversense system. Like the FreeStyle Libre, Eversense measures interstitial fluids via a sensor applied to your upper arm.

The key difference is that the sensor is implanted subcutaneously, or under the skin, and is worn for 90 days at a time. Once the sensor is applied, the Eversense system sends data to your smart device automatically every 5 minutes.

It also alerts you via a vibration alarm if your blood glucose falls out of your ideal range. Overall, users appreciate how this sensor is changed every 90 days versus 7 to 14 days like other brands.

However, some have experienced sensitivity alerts when wearing the sensor in direct sunlight. The PROMISE study evaluated the Eversense, concluding that the monitor sustained accuracy and safety up to days. Like the FreeStyle Libre and Eversense, the Guardian Connect sensor is worn on your arm to measure glucose via interstitial fluids.

But unlike any other CGM currently on the market, the Guardian Connect compiles time in range data. This data tells you how long your glucose is in your personal ideal range on any given day. You also need to change out your sensor every 7 days. This straightforward product allows you to program four reminder alarms, and the results can be processed in as quickly as 4 seconds.

You can also store up to test results on the device. The TrueMetrix meter is available at Rite Aid stores and online without a prescription. Keep in mind that you will also need to purchase lancets and test strips separately, both of which Rite Aid also sells. Similar to the Rite Aid TrueMetrix glucose meter, this version from Walgreens uses blood samples via a traditional finger-sticking process.

What sets it apart from the original TrueMetrix is its Bluetooth capabilities to deliver results to your smartphone. It works on both Android 4. Additionally, this Bluetooth version allows you to store twice as many test results: 1, at a time.

It claims to process your results in about 4 seconds. In addition to the cost of the meter, you will still need to buy lancets and test strips from the same brand.

Walgreens sells the meter and accessories without a prescription. You may consider the Libre, G6, Guardian Connect, or Eversense based on their features, as well as the accuracy and duration of sensor wear. While most insurance and Medicare do cover CGMs, these monitors are more expensive overall.

Depending on your insurance, they may offer coverage for one type of CGM but not another. With a prescription, you may be able to buy a CGM from a medical supply store online. If you do decide to purchase a glucose meter or monitor online, be sure you know the total costs up front, including any test strips, extra sensors, lancets, and accessories that may be sold separately.

However, you do need one for a continuous glucose monitor. Some smartwatches can connect to CGM systems, allowing you to check your readings on your watch. But none are capable of taking blood glucose readings directly. These seven glucose meters offer benefits — and some drawbacks — to consider when making your ultimate selection.

You can also talk about these monitors with your doctor. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

VIEW ALL HISTORY. Here are tips and brands to know. You can see what your blood glucose level is at any time. You can also review how your blood glucose level changes over a few hours or days and spot trends. Seeing your blood glucose levels in real time can help you make more informed decisions about the food and beverages you consume, the physical activity you do, and the medicines you take.

Keeping your blood glucose level in your target range can help prevent other health problems caused by diabetes. A continuous glucose monitor CGM estimates what your glucose level is every few minutes and keeps track of it over time.

A CGM has three parts. First, there is a tiny sensor that can be inserted under your skin, often the skin on your belly or arm, with a sticky patch that helps it stay there. These sensors are called disposable sensors. Another type of CGM sensor—called an implantable sensor—may be placed inside your body.

CGM sensors estimate the glucose level in the fluid between your cells, which is very similar to the glucose level in your blood. Sensors must be replaced at specific times, such as every few weeks, depending on the type of sensor you have.

The second part of the CGM is a transmitter. The transmitter sends the information, without using wires, to the third part, a software program that is stored on a smartphone, on an insulin pump , or on a separate device called a receiver. Your doctor may recommend that you use a CGM if you need insulin to manage type 1 diabetes , type 2 diabetes , or another form of diabetes.

Talk with your doctor about whether using a CGM could help you manage your diabetes. Doctors can prescribe CGMs for adults and children. Some models can be used for children as young as 2 years old. Your doctor may suggest using a CGM all the time or only for a few days to help adjust your diabetes care.

All CGMs estimate blood glucose levels, but they store and display the information in different ways. Some CGMs send and display information to your smartphone or receiver automatically. But you will need to scan the CGM with a separate receiver or smartphone every few hours to view and store the data.

A third type of CGM collects data about your blood glucose level for your doctor to download and review later. Doctors provide this type of CGM to check on your diabetes care, and you wear it for a limited time.

For some CGM models, you may need to do a finger-stick test with a standard blood glucose monitor to calibrate the system and make sure the CGM readings are correct.

Many CGMs work with apps that have special features, such as. For safety, it is important to act quickly if a CGM alarm sounds when your glucose level is too low or too high. You should get help or follow your treatment plan to bring your glucose level into a healthy range.

The CGM will create an alert and might display a graphic that shows whether your glucose level is rising or dropping—and how quickly—so you can choose the best way to reach your target range.

Over time, keeping your glucose levels in the healthy range can help you stay well and prevent diabetes complications.

Wright, Jr. 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.

I loved getting real-time continuous readings without having to scan the sensor with my phone. I also enjoyed the longer foot Bluetooth range, which is 13 feet longer than the other three sensors.

The sensor remained securely attached for the day period—without a hard-to-scrub adhesive ring. Simon Hill. Brenda Stolyar. Parker Hall. Medea Giordano. If you want a deep dive and have the time, interest, and extra funds, the Nutrisense program is your best bet.

Two factors set Nutrisense apart from other programs: detailed learning and personalized nutritionist guidance.

Nutrisense uses an Abbott FreeStyle Libre 14 day CGM. The sensor provides real-time continuous readings as long as the sensor is scanned every eight hours. As with the Libre 2, missing data is populated once the sensor is scanned. 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.
