By understanding the best practices for Dexcom G7 placement, you can optimize the accuracy and effectiveness of your CGM readings.

Before we delve into placement considerations, let’s briefly explore the Dexcom G7 CGM system. Dexcom G7 is a cutting-edge technology that enables individuals with diabetes to monitor their blood glucose levels continuously. It consists of a small sensor that is inserted under the skin and a transmitter that sends glucose readings to a receiver or smartphone app.

The Dexcom G7 provides real-time data, alerts for high and low blood sugar levels, and trend information, empowering users to make informed decisions about their diabetes management.

Importance of proper Dexcom G7 placement

Proper placement of the Dexcom G7 sensor is crucial for accurate and reliable glucose readings. The sensor measures glucose levels in the interstitial fluid, which surrounds the body’s cells. Placing the sensor in an appropriate site ensures that it can accurately detect changes in glucose levels. Incorrect placement may lead to inaccurate readings, which can impact diabetes self management decisions and compromise overall health.

When selecting a placement site for your Dexcom G7 sensor, several factors should be taken into account. These factors include proximity to capillary-rich areas, comfort, ease of insertion, sensor stability, and interference with daily activities.

Moreover, Dexcom has explained some additional factors that must be taken into account while choosing the Dexcom G7 placement site.

Keep the sensor at least 3 inches (8 centimeters) away from any insulin pump infusion set or injection site. This helps prevent interference or disruption of insulin delivery.

Avoid placing the sensor near waistbands, scarring, tattoos, irritation, or bones. These areas may affect the sensor’s accuracy or cause discomfort.

Ensure that the sensor is unlikely to be bumped, pushed, or laid on while sleeping. This helps maintain a secure and stable placement throughout the night.

Refer to the Dexcom G7 product instructions for detailed information and guidance on Dexcom G7 sensor placement, and any other specific questions you may have.

Recommendations for different lifestyles & activities

When selecting Dexcom G7 placement sites, it is essential to consider your lifestyle and activities. For athletes or individuals engaged in intense physical activities, areas less prone to movement or friction, such as the abdomen or upper buttocks, may be more suitable.

Those who require a more discreet placement may opt for the upper buttocks, back of the upper arms, or calf. It is crucial to strike a balance between accuracy, comfort, and practicality based on your individual needs.

Let’s explore some common placement sites and discuss their suitability for Dexcom G7 sensors.

Dexcom G7 abdomen placement

The abdomen is a popular Dexcom G7 placement site due to its proximity to capillary-rich areas. It is recommended to place the sensor around the belly button area, ensuring a minimum distance from scars, bony prominences, and the waistband of clothing. The abdomen offers good stability and easy access for sensor insertion and removal, making it a convenient site for many individuals.

G7 on upper buttocks

The upper buttocks, also known as the love handle area, can be a suitable site for Dexcom G7 placement. It provides good stability and comfort for sensor wear, especially for individuals who prefer a discreet placement option. When using the upper buttocks, it is important to avoid areas with excessive fat or muscular tissue to ensure proper sensor insertion.

Back of upper arms

The back of the upper arms is another viable option for Dexcom G7 sensor placement. This site offers excellent stability and easy access to sensor applications. However, it may be more challenging for self-insertion, as assistance may be required. It is important to select a location with sufficient fat and avoid areas with prominent muscles to enhance sensor accuracy.

Dexcom G7 placement on thighs

The thighs are commonly chosen as Dexcom G7 placement sites, particularly for active individuals. They offer good stability and accessibility, and many people find this site comfortable. When placing the sensor on the thigh, it is crucial to avoid areas that experience excessive friction or pressure from clothing or physical activities.

Common placement challenges and solutions

While Dexcom G7 placement is generally straightforward, certain challenges may arise. Here are some common challenges and their solutions:

Adhesion issues: If the sensor does not adhere well, try cleaning the area more thoroughly, using additional adhesive products like patches or tapes, or consult with your healthcare provider for alternative solutions.

Sensor discomfort: If you experience discomfort from the sensor, try adjusting the placement site slightly or consider trying alternative placement sites. If discomfort persists, consult with your healthcare provider for guidance.

Inaccurate readings: Inaccurate readings may occur if the sensor is not properly inserted or if there are issues with the placement site. Double-check the sensor insertion technique and ensure the site is suitable for accurate readings.

To ensure successful Dexcom G7 sensor placement, consider the following tips:

Cleanse the placement site with an alcohol wipe and allow it to dry before the sensor application.

Rotate placement sites to prevent overuse of a particular area.

Avoid areas with significant scar tissue or bony prominences, as they can affect sensor accuracy.

Ensure the adhesive area is free from lotions, oils, or excessive hair, as these can compromise adhesion.

Apply firm pressure to the sensor upon insertion to promote proper adhesion and sensor-to-tissue contact.

Follow the recommended sensor insertion angle and technique provided by Dexcom for optimal performance.
