Dexcom G7 FAQs
How long does a Dexcom G7 sensor last?
The Dexcom G7 sensor, used for continuous glucose monitoring, is designed to last for 10 days. This period allows for ongoing, real-time tracking of your glucose levels. After 10 days, the sensor needs to be replaced to maintain accuracy and reliability. Additionally, the Dexcom G7 includes a 12-hour grace period beyond the initial 10 days, offering some flexibility before a new sensor must be applied. This grace period helps ensure there’s ample time to change the sensor without disrupting glucose monitoring.
How do I apply the Dexcom G7 sensor?
Applying the Dexcom G7 sensor is simple and user-friendly, thanks to its integrated applicator. Start by washing your hands and selecting a clean, flat area on your abdomen or upper arm for placement, avoiding any spots with scars, tattoos, or excessive movement. Clean this area with an alcohol wipe and allow it to dry completely. Next, open the sensor package and peel back the adhesive backing from the sensor’s patch. Place the adhesive side on the prepared skin site, ensuring it's secure. Then, press the button on the applicator to insert the sensor beneath the skin. After insertion, gently press around the adhesive to make sure it sticks well. The sensor will automatically activate, and it will be ready to start monitoring your glucose levels.
Can I swim or shower with the Dexcom G7 sensor?
Yes, you can swim or shower with the Dexcom G7 sensor. The sensor 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. However, after exposure to water, it's essential to check that the sensor and its adhesive patch are still securely in place. If the adhesive starts to peel, consider using additional medical tape to reinforce it.
What is the difference between the Dexcom G6 and G7 systems?
The Dexcom G6 and Dexcom G7 systems both serve the purpose of continuous glucose monitoring, but the G7 introduces several enhancements that make it more user-friendly and efficient. The G7 sensor is significantly smaller, combining the sensor and transmitter into a single unit, which simplifies the application process and reduces its profile on the body. It also features a shorter warm-up time of just 30 minutes compared to the G6's 2 hours, allowing for quicker access to glucose readings. Both systems offer a 10-day wear period, but the G7 includes a 12-hour grace period, giving users more flexibility for sensor changes. In terms of accuracy, the G7 provides improved reliability in glucose readings and typically does not require calibration. The G7's integrated applicator and updated app offer a more intuitive user experience, with enhanced alert options and a more streamlined interface. These improvements make the Dexcom G7 a notable upgrade over the G6, offering greater convenience and performance for users managing their diabetes.
Can you buy the Dexcom G7 sensor over the counter?
Yes, you can buy the Dexcom G7 over the counter at Diabetic Warehouse without needing a prescription. Diabetic Warehouse offers different purchasing options, such as a single sensor pack, a pack of three sensors, and a starter pack that includes three sensors along with one Dexcom G7 receiver. These options provide flexibility and convenience for those looking to manage their glucose levels effectively without the need for a doctor's prescription.
Can I wear the Dexcom G7 sensor through airport security or during a flight?
Yes, you can wear the Dexcom G7 through airport security and while flying. The Dexcom G7 sensor is designed to be safe for use during air travel. It is not affected by airport security scanners or airplane travel conditions. You can keep the sensor attached and continue to monitor your glucose levels as usual throughout your journey. It's advisable to inform security personnel about the sensor if they ask about any medical devices you are carrying, although it typically does not require special handling during screening.
Can you use the Dexcom G7 without the receiver?
Yes, you can use the Dexcom G7 without the receiver. The G7 sensor sends glucose data directly to smartphones and other compatible devices using Bluetooth. This means you can monitor your glucose levels in real-time, view trends, and receive alerts on your mobile device without the need for an additional receiver. It's a convenient option for users who prefer to manage their diabetes using their smartphone or other compatible gadgets for continuous monitoring throughout the day.

Dexcom G7 vs. FreeStyle Libre 3 Comparison
The Freestyle Libre 3 and Dexcom G7 are two popular continuous glucose monitoring systems that offer different features and benefits. The Libre 3 boasts a longer sensor wear time of 14 days compared to the G7's 10 days. Both systems send real-time glucose readings to your smartphone, but the Libre 3 does so every minute while the G7 does so every 5 minutes. One advantage of the G7 is that it doesn't require any finger sticks for calibration, while the Libre 3 may occasionally require them for backup. When it comes to alerts, the Libre 3 offers optional notifications for low and high blood sugar, while the G7 provides more customizable alerts for highs, lows, and rapidly changing levels. Both systems are highly accurate, with the Libre 3 having a slightly lower MARD (a measure of accuracy) of 7.9% compared to the G7's 8.2%. Both systems are user-friendly, with push-button applicators for easy sensor insertion. They are also compatible with both iOS and Android devices. While the Libre 3 is water-resistant up to 3 feet for 30 minutes, the G7 is fully waterproof up to 2.4 meters. In terms of additional features, the Libre 3 has a built-in hypoglycemia safety alarm that alerts users when glucose is below 55 mg/dl, while the G7 automatically sends data to the Dexcom Clarity cloud, which can be accessed by both users and healthcare providers. While both the Freestyle Libre 3 and Dexcom G7 offer integration with insulin pumps, their compatibility varies. The Freestyle Libre 3 is currently only compatible with the mylife Loop automated insulin delivery system. However, Abbott, the manufacturer of the Libre 3, has plans to expand compatibility to other pumps in the near future. On the other hand, the Dexcom G7 is compatible with a wider 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 option for those who are already using or planning to use an insulin pump in conjunction with their continuous glucose monitor.
How much does a Dexcom G7 sensor cost?

Does insurance cover the Dexcom G7?
Whether insurance covers the Dexcom G7 depends on your insurance plan and individual circumstances. Many insurance plans, including Medicare and private insurers, often cover part or all of the costs if it's deemed necessary for managing diabetes. This typically requires a prescription from your doctor and may involve meeting certain criteria, such as specific glucose monitoring needs or documented medical necessity. To find out if your insurance covers the Dexcom G7, it's best to check directly with your insurance provider. They can provide details on coverage, any required documentation, and steps for approval.
