Introduction to Dexcom G7 CGM Sites
If you’ve been using a Dexcom G7 continuous glucose monitor (CGM), you might be wondering about the best sites for placement to ensure accuracy and minimize failures. While the FDA has approved its use on the back of the arm, personal experiences suggest there are other effective places on the body.
Why The Back of the Arm Might Not Be Optimal
Despite being FDA-approved, for some, the back of the arm has proven to be one of the least reliable spots. Users have reported frequent issues like compression lows due to pressure during sleep and the sensor being accidentally knocked during daily activities.
The Upper Thigh: A Preferred Spot
One of the preferred placements is the upper thigh. This area tends to allow for accurate readings, fewer signal losses, and minimal interference from daily activities. It’s also less likely to experience compression lows, provided it’s not placed directly on the side.
Stomach Placement: A Reliable Choice
Another preferred location for the Dexcom G7 is the stomach. It offers reliable readings and is discreet. Placing it above the beltline helps avoid snags from clothing and maintains consistent connectivity with monitoring devices.
The Lower Back for Minimizing Interference
For those who are not as active or do not sleep primarily on their backs, the lower back can be an excellent site. It stays out of the way during most activities and does not interfere with insulin injection sites. However, those who frequently sit against firm surfaces should consider potential compression effects.
Exploring Alternative Placements
If you’re feeling adventurous, alternative sites like the front of the arm, forearm, or calf might be worth a try. Though these are less common and require caution due to potential off-label use risks, they could offer similar benefits to more conventional sites.
Off-label Use and Its Implications
Wearing your sensor in non-standard locations is considered off-label use. This means there could be a lack of support from Dexcom in the event of failures. However, discussing potential placements with your healthcare provider can offer guidance and minimize risks.
Overcoming the Challenges
Regardless of placement, many users encounter challenges such as signal loss and sensor detachment. Using alternatives like fabric overlay tapes can improve sensor adhesion and comfort, minimizing the issues related to placement site friction and irritation.
Conclusion: Finding What Works For You
Ultimately, the best place for your Dexcom G7 CGM depends on your lifestyle and personal preferences. Experimenting with various sites while considering professional medical advice can help identify the most effective placement for your management of diabetes.
