Dexcom G4 is a new generation of CGM or continuous glucose monitoring technology. A CGM device is used to track blood sugar trends to help prevent hyperglycemia (elevated blood sugar) or hypoglycemia (low blood sugar) before it becomes a severe problem.
As with the Dexcom 7 (the older generation) it does not replace daily glucose monitoring but it is used in conjunction. Dexcom has been a world leader in these systems and this G4 generation offers even more with enhanced features including increased convenience and better reliability. Blood sugar monitoring gives a snapshot of your results whereas CGM gives you a constant picture. Blood sugars are influenced by food, stress, medications, exercise and sleep patterns.
CGM G4 Continuous Glucose Monitor can warn you to change things before they happen. There is an audible alarm system which can be set at low or high volume depending on your needs to alert you to a possible problem. The Dexcom platinum sensor is placed under the skin for 7 days and measures glucose in the interstitial fluid. The G4 sensor is 60% smaller than the original device which reduces inflammation at the site and decreases the local immune response. This allows for quicker healing, more accuracy and less patient discomfort. The new receiver comes in vibrant colors including blue, black and pink along with a colored LCD easy to read screen. The G4 transmitter also encourages more flexibility for the patient since the range between the receiver and transmitter has increased from 5 feet to 20 feet. You are now able to move around and live life more freely with added comfort and extra information. The Dexcom 4 is easy to learn, easy to use and easy to wear with excellent accuracy.
