I tried the Dexcom Stelo, one of the best mobile devices for monitoring glucose.
Continuous glucose monitors (CGMs) have been crucial for my health after suffering a heart attack four years ago. Recently, I tried the Dexcom Stelo over-the-counter CGM, and I have been very impressed.
Four years ago, my life took an unexpected turn when I had a heart attack at the age of 33. Although a quick coronary angioplasty showed that my heart was mostly fine, tests conducted at that time revealed a larger chronic issue: I am diabetic. Since that diagnosis—which I was already anticipating given my family history with type 2 diabetes—I have been working intensively to transform my life and diet, and a continuous glucose monitor (CGM) has been fundamental in that process.
You may not be familiar with Dexcom or Abbott, the two companies that dominate the CGM market, unless you are a health tech advocate or a diabetic like me. However, you may have heard something about the Dexcom Stelo or the Abbott Lingo. For the first time, a CGM is available over the counter, but as is often the case, it is necessary to investigate if there is a downside. After spending two weeks testing the Dexcom Stelo, I can say that it is an incredible product for anyone interested in diabetes. Still, before you decide to buy one, it’s important to note that it may not be the most suitable option if you are diabetic and have used a previous Dexcom product.
A device like the CGM is valuable for diabetics for several reasons. You might be wondering, why would a CGM be useful? Of course, glucose can be measured through a finger prick, but a CGM provides much-needed context. A finger prick result only offers a snapshot, without indicating whether the sugar level is rising or falling. Moreover, a measurement taken first thing in the morning does not reflect the behavior of the previous day, which can lead to incorrect adjustments in diet or medication.
Regarding my experience with CGMs, I initially tried the Freestyle Libre because healthcare providers in the U.S. did not cover Dexcom CGMs. After using various models of Freestyle Libre, I finally tried the Dexcom G7, which turned out to be a game changer in my diabetes management. Having experience with five different CGMs, I have discerned key information for long-term diabetes care, although the Dexcom Stelo and Abbott Lingo lack certain data that are critical for individuals with specific needs like mine.
Despite these shortcomings, the Dexcom Stelo offers multiple advantages for most people. Its design aims to provide the functionalities of the Dexcom G7 at a lower price and without a prescription. It uses similar hardware and the same applicator, differentiated mainly by software and packaging. This model is particularly valuable for those who cannot obtain a CGM through the healthcare system.
The Stelo app is almost identical to that of the G7, providing valuable information about glucose levels, trends, and historical data. However, the differences between the Dexcom G7 and the Dexcom Stelo are significant. While the Stelo is more accessible for many, it lacks certain features that might be important for diabetics with more complex conditions. For instance, it has a limit of 250 mg/dl on post-meal sugar readings, which may not be sufficient for control in specific cases. Additionally, it does not allow for customizing glucose target ranges, limiting itself to two options.
In summary, the Dexcom Stelo is ideal for most diabetics and represents an effective entry into glucose monitoring. Furthermore, the recent partnership between Dexcom and Oura to sync glucose data opens up new possibilities in comprehensive health monitoring. It is currently a good time to delve into glucose tracking with accessible and functional options like those offered by Dexcom.
