The Dexcom G6 Continuous Glucose Monitoring (CGM) system is an advanced, FDA-approved device designed to help individuals with type 1 and type 2 diabetes manage their blood glucose levels more effectively. This CGM comprises an auto-applicator, transmitter, and display device. The display device features a receiver and a compatible smart device. Unlike traditional monitoring methods that require routine fingerstick, the Dexcom G6 provides real-time glucose readings every five minutes, offering a more convenient and comprehensive approach to glucose monitoring. The Dexcom G6 is suitable for individuals aged two years and older and is designed to support better glycemic control by providing timely and accurate glucose information. Its user-friendly design and advanced features make it a valuable tool for those seeking to manage their diabetes more effectively.

• This system continuously tracks glucose levels, sending updates every five minutes to a compatible smart device or Dexcom receiver.
• The system is factory-calibrated, eliminating the need for routine fingerstick tests for calibration purposes.
• Users can set personalized high and low glucose alerts, including an "Urgent Low Soon" alert that warns of potential severe hypoglycemia (<3.1mmol/L) up to 20 minutes in advance.
• This system allows users to share glucose data with up to 10 followers, such as family members or healthcare providers, enhancing support and care coordination.
• Dexcom G6 CGM system is compatible with various smart devices, enabling users to view glucose trends and patterns conveniently.

• Select a location on your abdomen and upper buttocks (for children aged 2–17) and back of upper arm (for people over the age of 18) that is free from scarring, tattoos, or irritation.
• Clean the chosen location with alcohol wipes. Ensure, the site fully dries before application.
• Peel the adhesive backing from the sensor applicator with the 4-digit code, being careful not to touch the adhesive surface. Do not throw away this adhesive backing, as you may need to scan or manually enter the 4-digit code for a new sensor session.
• Place the applicator against your skin. Fold and break off the safety guard, then press the button to insert the sensor.
• Allow the sensor to rest at equilibrium in the spot and push the button gently without pushing the whole applicator.
• After inserting the sensor, snap the transmitter into the sensor holder until it clicks into place.
• Pull the applicator away after hearing the click. This shows the sensor is inserted.
• Open the Dexcom G6 app or receiver, enter the new sensor code when prompted, and start the sensor session. The warm-up period will take approximately two hours.

• On your Dexcom G6 app or receiver, select "Stop Sensor" to end the current session.
• Peel off the sensor patch like a bandage. The transmitter, sensor, and holder will come off with the patch.
• After removing the patch, press down on the edge of the transmitter holder to release and slide out the transmitter.
• Discard the used sensor and applicator according to your local regulations for medical waste.
• Reuse the Transmitter, as it has a battery life of approximately 90 days and it can be reused with multiple sensors until you receive a notification that it needs to be replaced.
• Apply a New Sensor by applying the steps to insert a new sensor and restart your monitoring session.

The Dexcom G6 sensors last for 10 days per session. You must replace them after this period to ensure accurate glucose monitoring. Although some users have reported using the sensors beyond this 10-day mark, Dexcom recommends replacement after 10 days for optimal performance. In addition to this, you must replace the new transmitter within 3 months. This is because the transmitter communicates data from the sensor to your device and has a 3-month battery life.

Yes, the Dexcom G6 CGM is typically covered by most insurance providers in the U.S., including Medicare, Medicaid, and many commercial health insurance providers. However, coverage criteria differ on factors such as diabetes type, insulin usage, and specific plan requirements. Here is how to check your coverage:

• Reach out to your insurance company to inquire about coverage for CGM.​
• Check with your doctor to ensure that the Dexcom is appropriate for your treatment plan.​
• Dexcom offers a free insurance benefits check to help you understand your coverage options.

If your insurance does not cover the Dexcom G6, the out-of-pocket cost can be significant. Thus, Dexcom provides a savings program that offers discounts to eligible individuals, potentially reducing the cost by over 50%. ​For more detailed information or assistance, you can visit the Dexcom Savings Center or contact your healthcare provider.

It is important to store your Dexcom G6 sensor properly to ensure their optimal performance and longevity. Here are the recommended storage guidelines:

• Store your sensors at temperatures between 36°F and 86°F (2°C and 30°C).
• Store them in dry place, avoiding humid areas.
• Keep the sensors in sterile packaging until you are ready to use them.
• Do not keep the sensors in the freezer.

Yes, some people have reported skin reactions to the Dexcom G6 sensor adhesive. These reactions may occur as swelling, redness, blistering, and infection. Some users have also reported allergic reactions when their skin comes in contact with allergens in the adhesive. A study has identified 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate (MBPA), as a potential allergen in G6 sensor. Here are tips to prevent and manage skin reactions:

• Clean the skin on the application area with oil-free, anti-microbial soap and dry thoroughly.
• Exfoliate the area gently if you have oily skin.
• Trim the hair in the area using a dry razor.
• Do not use any lotion or oil-containing moisturizer directly on the area.
• Apply the sensor only when the skin is dry. Avoid inserting the sensor immediately after a bath or shower.
• If you have sweaty skin, using a solid or spray antiperspirant may help. Apply it in an oval shape around the area and wait for 10-15 mins. Insert the sensor on the clean skin in the center of this oval area. Take care to use non-scented antiperspirant, as scented ones may cause irritation.

Dexcom G6 sensors have a 10-day lifespan, after which they must be replaced with a new sensor. Many users have reported extending sensor life beyond the recommended period through various methods, which are not approved by Dexcom and may compromise sensor accuracy and pose potential health risks. Dexcom's official stance is that the G6 sensor should be replaced after 10 days of use. For those seeking longer sensor wear durations, the Dexcom G7 15-Day system has been approved by the FDA. It allows for continuous glucose monitoring for up to 15.5 days, offering a longer period between sensor replacements. If you plan to use the sensor beyond the recommended period, it's crucial to consult with your healthcare provider to ensure safety and accuracy in your glucose monitoring.
