Living well with diabetes requires vigilant management of blood sugar levels. Thankfully, technology has come a long way in helping individuals with diabetes keep their glucose levels in check. One of the most valuable advancements in this field is the development of Continuous Glucose Monitoring (CGM) devices. These innovative tools have revolutionized diabetes management by providing real-time information on blood sugar levels.
In this article, we’ll explore three leading CGMs on the market: Dexcom, Freestyle Libre, and Medtronic Guardian. Let’s delve into the advantages and limitations of these CGMs to help you make an informed decision about which one might be the best fit for you or your loved one with diabetes.
The Evolution of CGMs
Traditional glucose monitoring involves fingerstick tests using a glucometer, which provides only periodic information on blood sugar levels. In the case of type-I diabetes, close monitoring for blood sugar levels is required and one needs to prick their fingers several times a day. On the other hand, CGMs offer continuous, real-time monitoring, allowing users to track trends and make informed decisions about their diabetes management.
These devices typically consist of a tiny sensor inserted under the skin that continuously measures glucose levels in the interstitial fluid. The sensor communicates with a receiver or smartphone app, providing data on glucose trends, highs, and lows throughout the day and night. This valuable information empowers individuals with diabetes to make timely adjustments to their medication, diet, and lifestyle.
Dexcom is a pioneer in CGM technology. Their Dexcom G6 and G7 systems are well-regarded for their accuracy and user-friendly design. One standout feature is their exceptional real-time data-sharing capabilities, which allow users to share their glucose information with caregivers or healthcare providers remotely. This feature can be a game-changer, especially for parents of children with diabetes or individuals needing close monitoring.
Advantages of Dexcom
Dexcom CGMs are known for their precise glucose readings, making them a trusted choice for insulin dosing decisions.
2. Data Sharing
The ability to share data in real-time like three to five minutes can enhance the support network for those managing diabetes.
Limitations of Dexcom
Dexcom CGMs can be more expensive than other options, which all insurance plans may not cover.
2. Sensor Changes
Sensor replacements are required every 10 days, which can be inconvenient for some users.
Abbott’s Freestyle Libre system has gained popularity for its convenience and affordability. Instead of a traditional CGM, it uses a small sensor applied to the back of the upper arm and doesn’t require routine fingerstick calibration. Users can scan the
