Yes, the Dexcom G7 Continuous Glucose Monitoring (CGM) system can be worn on the arm. Specifically, the sensor is designed for insertion on the back of the upper arm for users aged 2 years and older.
Dexcom G7 sensors are engineered for accuracy and comfort when placed in the recommended areas. Proper placement is crucial to ensure the device functions as expected and provides reliable glucose readings.
Recommended Placement for Dexcom G7 Sensors
The Dexcom G7 sensor has specific insertion sites that are clinically validated for optimal performance across different age groups. Adhering to these guidelines helps ensure the sensor accurately measures glucose levels.
Here are the recommended sensor placement sites:
| Sensor Placement Site | Recommended Age Group |
|---|---|
| Back of Upper Arm | 2 years and older |
| Upper Buttocks | 2-6 years old |
It is important to note that the Dexcom G7 sensor should not be worn on other sites, as doing so may compromise its performance and lead to inaccurate readings. Always follow the instructions provided with your Dexcom G7 system for sensor insertion.
Why Proper Placement Matters
Choosing the correct insertion site for your Dexcom G7 sensor is vital for several reasons:
- Accuracy: Recommended sites have been tested to ensure the sensor can accurately read interstitial fluid glucose levels.
- Reliability: Proper placement helps maintain consistent sensor contact with the skin, leading to more stable data transmission.
- Comfort: Designated areas are typically less prone to movement or pressure, which can enhance comfort during the wear period.
- Effectiveness: Using unapproved sites might result in the sensor not working as expected, potentially leading to misleading glucose data.

Tips for Sensor Application on the Arm
When applying the Dexcom G7 sensor to the back of the upper arm, consider the following practical insights:
- Choose a Flat Area: Select a site on the back of your upper arm that is relatively flat and free from excessive hair, scars, or irritation.
- Clean the Skin: Thoroughly clean the insertion area with an alcohol wipe and let it air dry completely before applying the sensor. This ensures good adhesion and reduces the risk of infection.
- Avoid Pressure Points: Choose a spot that won't be constantly rubbed by clothing, seatbelts, or during sleep to maintain sensor adhesion and comfort.
- Rotate Sites: If you frequently use the arm, consider alternating between your left and right upper arms for subsequent sensor applications to prevent skin irritation.
By following these guidelines, users can maximize the effectiveness and comfort of their Dexcom G7 CGM system.
