Introduction
The Dexcom G7 is a device I truly appreciate, but like any technology, it has its share of challenges. In this post, we will delve into five things that might not work as seamlessly as we’d hope with the Dexcom G7, based on personal experience and user feedback.
Signal Loss
One of the most vexing issues with the Dexcom G7 is frequent signal loss. This occurs when the sensor loses contact with your phone or receiver, leading to a lack of blood sugar readings. This issue is particularly frustrating since the primary purpose of the device is to provide continuous glucose monitoring.
Initial Inaccuracy
In the first 24 hours, accuracy can be a significant problem. Many users find that blood sugar readings during this period are erratic. To combat this, it’s recommended to perform finger sticks and spot checks to ensure accuracy during this initial phase.
Compression Lows
Compression lows are another concern, typically happening when there’s pressure on the sensor, such as during sleep. These false low readings can lead to unnecessary alarms, disrupting sleep and potentially causing users to treat low blood sugar that isn’t real.
Choppy Graphs
The Dexcom G7’s graph can sometimes appear choppy or jumpy, as the device seems to self-adjust more frequently. While the intention is to enhance accuracy, it can result in unpredictable readings. Thus, users should be cautious and patient before responding to these abrupt changes.
Limited Sensor Lifetime
Unlike previous models, the Dexcom G7 sensor cannot be restarted after its intended use period, limiting its longevity. For users who may struggle with the cost of new sensors, this is a significant disadvantage.
Managing Signal Loss
Dexcom suggests keeping the phone or receiver on the same side of the body as the sensor to reduce signal loss. Other recommendations include keeping the app open and avoiding low power mode on devices.
Dealing with Inaccuracy
To overcome initial inaccuracies, users are advised to rely on finger sticks initially. Engaging with how the body feels can also aid in determining whether a reading is erroneous.
Identifying False Low Readings
Recognizing compression lows is crucial. Checking the graph for sudden drops without a descending slope can indicate a false low, preventing unnecessary treatments.
Overall Reflection
While the Dexcom G7 has its challenges, being aware of these issues can help users better manage their experience. Future updates may address some of these concerns, potentially enhancing the performance of this device.
Conclusion
Despite its shortcomings, the Dexcom G7 remains a vital tool for those managing diabetes. Sharing experiences and solutions can lead to improvements, both personally and within the technology itself. Feedback and comments are encouraged to foster a collective effort in the diabetes community.
