Continuous glucose monitoring (CGM) systems have revolutionized diabetes management by providing an easier and more convenient way of monitoring blood glucose levels. Two popular CGM systems are the Dexcom G7 and Freestyle Libre 3. In this article, we will compare and contrast these systems in terms of accuracy, wearability, features and technology, cost, and user feedback.

Accuracy is a critical factor in glucose monitoring systems, and both Dexcom G7 and Freestyle Libre 3 use different methods to measure blood glucose levels. Dexcom G7 uses a sensor that is inserted under the skin to measure glucose levels in interstitial fluid, while Freestyle Libre 3 uses a sensor that is placed on the skin's surface. The results of both systems are similar, with Dexcom G7 being more accurate during hypoglycemia and hyperglycemia episodes.

Both devices are small and discreet, with Dexcom G7 measuring 1.14 inches in diameter and 0.18 inches in height and Freestyle Libre 3 measuring 1.57 inches by 0.87 inches and 0.24 inches in height. Dexcom G7 is worn on the back of the upper arm, while Freestyle Libre 3 is attached to the skin with an adhesive. Both devices offer convenience in terms of no fingerstick calibration required, but Freestyle Libre 3 requires the user to scan the sensor with a handheld reader or smartphone to get glucose readings.

Dexcom G7 has a customizable alert system that allows users to set alarms for high and low glucose levels, and it is compatible with many smart devices. Freestyle Libre 3 uses Flash glucose monitoring technology, which eliminates the need for a sensor insertion device or daily calibration, and has a built-in blood glucose meter. Freestyle Libre 3 can store up to 8 hours of glucose data, and users can view their glucose data by scanning the sensor with a handheld reader or smartphone.

In terms of cost, the Freestyle Libre 3 sensor buy online is generally considered more affordable than the Dexcom G7, but the cost may vary depending on insurance coverage, location, and purchasing options. Both systems may be covered by insurance plans, but the coverage may depend on various factors such as the patient's medical history, the type of plan, and the insurance provider.

Users of both systems have provided feedback on various aspects, including accuracy, wearability, convenience, and overall satisfaction. Overall, both Dexcom G7 and Freestyle Libre 3 are advanced glucose monitoring systems that offer various features and benefits for patients with diabetes. The main differences between the two systems are their accuracy, wearability, convenience, cost, insurance coverage, and user feedback.
