What Are Dexcom CGM Systems, and Why Do You Need One
Dexcom's CGM systems, such as the G6 and G7, offer continuous monitoring of glucose levels. Rather than relying on traditional finger pricks, these systems allow you to track your blood sugar levels in real-time, sending the data directly to your smartphone or a dedicated receiver. This constant feedback helps you make informed decisions about your diet, exercise, and insulin use.
The importance of CGM systems for people with diabetes is significant. They help manage glucose levels more effectively and provide an added layer of confidence in day-to-day activities. With the G6 and G7, you're not just getting a tool for monitoring glucose levels, you’re getting peace of mind.
Beneficial Features of Dexcom Systems
Here are some key benefits of using Dexcom G7 and G6 CGM systems.
• Real-Time Glucose Monitoring: Both the G6 and G7 send glucose readings directly to your smartphone or receiver every five minutes. You don’t have to guess your glucose levels, as readings are updated regularly.
• Smart Alerts That Actually Help: You can set custom alerts for high and low glucose levels. The system can warn you before you go too high or too low. You can share your data with family members who can receive alerts on their phones.
• Long-Lasting Sensors: Each G7 sensor lasts 10 days with a 12-hour grace period. G6 also runs for 10 days, although it requires a separate transmitter that needs to be replaced approximately every three months.
• The G7 Advantage: G7 is approximately 60% smaller than G6, which reduces the warm-up time from two hours to about 30 minutes. The applicator and sensor come as one piece, making insertion simpler. Also, you do not need to routinely calibrate the device. With updates to sensor technology, the Dexcom G7 is designed to provide improvedaccuracy, especially at extreme highs and lows.
• Integration with Other Devices: Both systems connect with insulin pumps, diabetes apps, and smartwatches. Your diabetes data can be accessed within a connected ecosystem.
