Can You Swim with Dexcom G7?

The ability to swim with a CGM device is a crucial consideration for many users, especially those who lead active lifestyles or enjoy water-based activities. The Dexcom G7 is designed to be water-resistant, but what does that mean in practical terms?

Water Resistance of the Dexcom G7

The Dexcom G7 is rated as water-resistant, meaning it can withstand exposure to water to a certain extent. According to Dexcom, the G7 can be submerged in water up to 8 feet (2.4 meters) for a maximum of 24 hours. This level of water resistance makes it suitable for activities such as swimming, showering, and even light snorkeling.

However, it’s important to note that water resistance does not equate to waterproofness. The Dexcom G7 is not designed for prolonged or deep-water activities, such as scuba diving or high-impact water sports. Prolonged exposure to water, especially at greater depths, can compromise the device’s functionality and accuracy.

Practical Considerations for Swimming with Dexcom G7

While the Dexcom G7 is water-resistant, there are several practical considerations to keep in mind when using the device in aquatic environments:

Sensor Adhesion: The adhesive used to secure the Dexcom G7 sensor to the skin may weaken when exposed to water for extended periods. To ensure the sensor stays in place, users can apply additional adhesive patches or barriers, such as waterproof tape or specialized adhesive covers.
Temperature Sensitivity: The Dexcom G7 is designed to operate within a specific temperature range. Prolonged exposure to cold water, such as in open-water swimming, may affect the device’s performance. Users should monitor their glucose levels closely and be aware of any potential discrepancies.
Post-Swim Care: After swimming, it’s essential to dry the sensor and transmitter thoroughly to prevent moisture buildup, which could lead to sensor errors or malfunctions. Gently patting the device dry with a towel is recommended.
Device Monitoring: While the Dexcom G7 is water-resistant, it’s crucial to monitor the device’s performance during and after swimming. If users notice any irregularities in glucose readings or alerts, they should consult their healthcare provider or Dexcom support.

User Experiences and Testimonials

To gain a deeper understanding of the Dexcom G7’s performance in aquatic environments, it’s valuable to consider user experiences and testimonials. Many users have reported positive experiences with swimming while wearing the Dexcom G7, noting that the device remains functional and accurate during and after water exposure.

Positive Feedback

Reliability: Users have praised the Dexcom G7 for its reliability during swimming and other water-based activities. The device’s water resistance has allowed them to maintain consistent glucose monitoring without interruptions.
Comfort: The compact design of the Dexcom G7 has made it more comfortable to wear during swimming, with users reporting minimal discomfort or interference with their movements.
Ease of Use: The ability to sync the Dexcom G7 with smartphones and smartwatches has made it easier for users to monitor their glucose levels while swimming, providing peace of mind and convenience.

Challenges and Concerns

Adhesive Issues: Some users have reported challenges with the sensor’s adhesion during prolonged water exposure, necessitating the use of additional adhesive products to keep the sensor in place.
Temperature Variations: A few users have noted that extreme temperature changes, such as transitioning from cold water to warm environments, can temporarily affect the device’s accuracy.
Device Alerts: While the Dexcom G7 provides real-time alerts, some users have experienced delayed or missed alerts during swimming, highlighting the importance of manual glucose monitoring in certain situations.

Comparing Dexcom G7 with Other CGM Devices

To provide a comprehensive perspective, it’s useful to compare the Dexcom G7’s water resistance with other popular CGM devices on the market.

Dexcom G6

The Dexcom G6, the predecessor to the G7, is also water-resistant but with slightly different specifications. The G6 can be submerged in water up to 8 feet (2.4 meters) for a maximum of 24 hours, similar to the G7. However, the G7’s improved design and adhesive technology may offer better performance in aquatic environments.

Abbott FreeStyle Libre 2

The Abbott FreeStyle Libre 2 is another widely used CGM system. While it is water-resistant, it is rated for submersion up to 3 feet (1 meter) for 30 minutes, making it less suitable for prolonged swimming compared to the Dexcom G7.

Medtronic Guardian Connect

The Medtronic Guardian Connect is designed for water resistance up to 8 feet (2.4 meters) for 30 minutes. While it offers similar water resistance to the Dexcom G7, the Guardian Connect’s overall design and user experience may differ, influencing its suitability for swimming.

Tips for Maximizing Dexcom G7 Performance in Water

To ensure optimal performance of the Dexcom G7 during swimming and other water-based activities, consider the following tips:

Use Additional Adhesive: Apply waterproof adhesive patches or barriers to enhance the sensor’s adhesion during water exposure.
Monitor Glucose Levels: Regularly check your glucose levels before, during, and after swimming to ensure accuracy and address any discrepancies.
Dry the Device Thoroughly: After swimming, dry the sensor and transmitter thoroughly to prevent moisture-related issues.
Consult Healthcare Providers: If you have concerns about using the Dexcom G7 in water, consult your healthcare provider for personalized advice and recommendations.
