Which CGM Is The Best For You?

Not all continuous glucose monitors (CGMs) are created equally. They are unique, just like you and me. If you or a loved one has decided to make the switch to a CGM, you may be wondering which one is best? But the better question is, “Which CGM is best for me?” Three of the top CGMs currently on the market in the US are: Dexcom G6, Guardian Connect System, And Eversense CGM System. In this article, we’ll share what we’ve found in our research so you can make a better decision about which CGM will be right for you.

Best CGM For Children

If you have a child with diabetes, you know how stressful it can be when he or she is out of sight. You want to check your child’s glucose level while they’re at school, on the playground, or at a friend’s house. If that’s the case, real-time CGMs will be your best choice. (To learn more about the difference between real-time and intermittent CGMs, check out our article, What is a CGM?)

First-place: Dexcom G6

According to Dexcom, the Dexcom G6 is the only real-time CGM which can be used by children under 14 years of age, and even children as young as 2.This monitor can send texts to ten different phone numbers with glucose level updates. So you, your partner, and your child’s healthcare team can stay informed. Plus, the Dexcom G6 is permitted by the FDA to make treatment decisions without a fingerstick calibration.

Runner up: Guardian Connect System

Although the Guardian Connect CGM doesn’t automatically send glucose readings, it does have the Guardian CareLink Connect Platform. When your child scans their sensor with a monitor or smartphone, the reading will be texted to you. This is a small difference, but it is an extra step your child has to remember to take, to share their results. According Medtronic, The Guardian Connect CGM it is the only CGM approved for people 14 and older.

Best for Busy Adults

One of the main benefits of a CGM is less finger-sticking, which makes them great if you are always on the go. But some CGMs require more maintenance than others. Usually, that maintenance comes in the form of replacing your sensor and transmitter. Choosing a CGM with an easy to replace sensor and transmitter that you can insert at home will save you time, and is one less thing to worry about.

First-place: Dexcom G6

According to Dexcom, the Dexcom G6 has a sensor and transmitter that you can wear for up to 10 days. It also has an at-home applicator, so there is no need to make a doctor’s appointment.

Runner up: Eversense CGM System

According to Senseonics, the Eversense CGM System’s transmitter and sensor can be worn for up to 90 days. However, the Eversense transmitter and sensor need to be implanted surgically. This takes the runner-up spot because you will need to carve out sometime to see your doctor. 

Best for Water Resistance

Before you dive into the pool or jump into the ocean, you’re going to want to make sure that your CGM can handle it. Luckily, most CGMs are somewhat water-resistant, although some are more durable than others.

First-place: Dexcom G6

According to Dexcom, the Dexcom G6’s transmitter and sensor are water-resistant for up to 24 hours and a depth of up to eight feet of water. It is currently the most water-resistant CGM on the market. This is a perfect choice for those who participate in water sports like swimming laps or surfing.

Runner up: Guardian Connect System

According to Medtronic, the Guardian Connect is water-resistant for up to 30 minutes, and in up to eight feet of water, making it a strong contender for splashing in the waves. This CGM may not be the best long-term solution if you’re a serious swimmer. However, it should meet the needs of most low-intensity activities like floating in the pool.

Most User-Friendly App

Each CGM comes with its own smartphone app that functions as the monitor. These advanced apps can offer much more than what a traditional reader can, and places more information and functionality at your fingertips. While each CGM has an app with unique functions, these are the apps we feel are most innovative. As always, you should talk to your doctor when making a decision about which CGM is right for you.

First-place: Guardian Connect System

The Guardian Connect System comes with a diabetes assistant called Sugar.IQ. It uses the same predictive technology used for global weather patterns. This handy app can give you a detailed view of how certain foods and activities affect your glucose level, based on previous data. Over time, the app collects more information about your habits, which enables it to predict how your levels will change in the future.

Runner up: Eversense CGM System

The main differentiator of the Eversense app is how customizable it is. Eversense trusts you to understand your diabetes better than anyone, so their app gives you plenty of diabetes management options. For example, you can turn off the high glucose alert, or set “do not disturb” during an important meeting.

Longest Lasting Sensor and Transmitter

All CGMs have sensors, but not all of them have transmitters that send data to an app or monitor. (To learn more, read how to use a CGM). The sensor and transmitter don’t last forever, and their length of use can vary.

First-place: Eversense CGM System  

According to Senseonics, the Eversense CGM System’s transmitter and sensor can be worn for up to 90 days. This is much longer than the other three monitors on the market. However, the Eversense transmitter and sensor need to be implanted surgically. So, while the transmitter and sensor last the longest, they also require a trip to your doctor’s office.

Runner up: Dexcom G6 

According to Dexcom, the Dexcom G6 has a sensor and transmitter that you can wear for up to 10 days. It also has an at-home applicator for ease of use.

Overall Rankings

We’ve examined each device within specific categories according to the claims of their manufacturers, but who came out on top overall? We based our rankings on a count of first-place and runner up winners.

First-place: Dexcom G6

The Dexcom G6 got first-place for both the best CGM for children category and the best for your beach vacation category. This makes it the only CGM on our list with two first-place wins. The Dexcom G6 is the only CGM that is FDA approved for children in the US, a definite advantage over the competition. Plus, this CGM is water-resistant for up to 24 hours, more than double the time of all other CGMs on this list.

Second-place: Guardian Connect System

With a first-place win for most user-friendly app and two runners up wins for best CGM for children and best for your beach vacation, the Guardian Connect System is a strong second-place contender. Its app comes with its very own virtual diabetes assistant, it is FDA approved for children 14 years and older, and it is water-resistant for up to 30 minutes. 

Third-place: Eversense CGM System

The Eversense CGM System is lightyears ahead of the competition with a sensor and transmitter that lasts 90 days. Plus, its app is the most customizable of any of the other CGMs. This CGM is only in third place because some users don’t want to visit their doctors to have the system implanted every 90 days.
