Dexcom G7 FAQs
How long can a Dexcom G7 sensor last?
The Dexcom G7 sensor, used for continuous glucose monitoring, is designed to last for 10 days. This duration allows for continuous tracking of your glucose levels. After 10 days, the sensor needs to be replaced to maintain its accuracy and reliability. Additionally, the Dexcom G7 offers a 12-hour grace period beyond the initial 10 days, providing flexibility for sensor changes without interrupting glucose monitoring.
How do you apply the Dexcom G7 sensor?
Applying the Dexcom G7 sensor is straightforward with its integrated applicator. Start by washing your hands and choosing a clean, flat area on your abdomen or upper arm for placement, avoiding areas with scars, tattoos, or excessive movement. Clean the chosen area with an alcohol wipe and allow it to dry completely. Open the sensor package and remove the adhesive backing from the sensor’s patch. Place the adhesive side on the prepared skin site, ensuring it is secure. Press the button on the applicator to insert the sensor under the skin. After insertion, press around the adhesive to ensure it sticks well. The sensor will activate automatically and begin monitoring your glucose levels.
Can you swim or shower with the Dexcom G7 sensor?
Yes, you can swim or shower with the Dexcom G7 sensor. It is designed to be waterproof, making it suitable for various water activities and daily hygiene routines. You can safely wear the sensor while swimming in pools, lakes, or the ocean, as well as during showers or baths. It is water-resistant in up to 8 feet (2.4 meters) of water for up to 24 hours, ensuring it remains functional in wet conditions. After exposure to water, ensure the sensor and adhesive patch are still securely in place. Use additional medical tape if needed.
What sets the Dexcom G7 apart from the G6 system?
The Dexcom G7 and G6 systems both offer continuous glucose monitoring, but the G7 introduces enhancements for a more user-friendly experience. The G7 sensor is smaller, combining the sensor and transmitter into a single unit, simplifying application and reducing its profile. It features a shorter warm-up time of just 30 minutes compared to the G6's 2 hours, providing quicker access to glucose readings. Both systems offer a 10-day wear period, with the G7 including a 12-hour grace period for sensor changes. The G7 offers improved reliability in glucose readings and typically does not require calibration, enhancing user convenience. Its integrated applicator and updated app provide a more intuitive experience with enhanced alert options and a streamlined interface, making it a significant upgrade over the G6.
Can you purchase the Dexcom G7 sensor without a prescription?
Yes, you can purchase the Dexcom G7 sensor over the counter at Diabetic Warehouse. They offer various purchasing options, including single sensors, packs of three sensors, and starter packs that include sensors and a G7 receiver. These options provide flexibility and convenience for managing glucose levels effectively without needing a doctor's prescription.
Can you wear the Dexcom G7 sensor during air travel?
Yes, you can wear the Dexcom G7 sensor through airport security and during flights. It is safe for use during air travel and is not affected by airport security scanners or flight conditions. You can keep the sensor attached and monitor your glucose levels as usual throughout your journey. It's recommended to inform security personnel about the sensor if asked about medical devices, though it typically does not require special handling during screening.
Is it possible to use the Dexcom G7 sensor without a receiver?
Yes, you can use the Dexcom G7 without a receiver. The G7 sensor transmits glucose data directly to smartphones and other compatible devices via Bluetooth. This allows real-time monitoring, trend viewing, and alert reception on your mobile device without needing an additional receiver. It's a convenient option for users who prefer managing their diabetes using smartphones or compatible gadgets for continuous monitoring throughout the day.

Dexcom G7 vs. FreeStyle Libre 3: What are the differences?
The Dexcom G7 and FreeStyle Libre 3 are popular continuous glucose monitoring systems with distinct features. The Libre 3 offers a longer sensor wear time of 14 days versus the G7's 10 days. Both systems transmit real-time glucose readings to smartphones; however, the Libre 3 updates every minute compared to the G7's 5-minute intervals. The G7 doesn't require finger sticks for calibration, unlike the Libre 3, which may occasionally need them for backup. Regarding alerts, the Libre 3 offers optional low and high blood sugar notifications, while the G7 provides more customizable alerts for highs, lows, and rapid changes in levels. Both systems are highly accurate, with the Libre 3 boasting a slightly lower MARD (accuracy measure) of 7.9% versus the G7's 8.2%. Both systems feature user-friendly push-button applicators for easy sensor insertion and are compatible with iOS and Android devices. The Libre 3 is water-resistant up to 3 feet for 30 minutes, whereas the G7 is fully waterproof up to 2.4 meters. In terms of additional features, the Libre 3 includes a built-in hypoglycemia alarm alerting users when glucose drops below 55 mg/dl, while the G7 automatically sends data to the Dexcom Clarity cloud accessible to users and healthcare providers. While both the Freestyle Libre 3 and Dexcom G7 integrate with insulin pumps, their compatibility varies. The Libre 3 currently only works with the mylife Loop automated insulin delivery system. However, Abbott, the manufacturer of the Libre 3, plans to expand compatibility to other pumps soon. In contrast, the Dexcom G7 is compatible with a broader range of insulin pumps, including the iLet Bionic Pancreas, Omnipod 5, Tandem t:slim X2 with Control-IQ technology, Tandem Mobi System, and InPen. This makes it a more versatile choice for users already using or considering an insulin pump alongside their continuous glucose monitor.
