Until recently, most patients with diabetes performed SMBG using a glucose meter, which required intermittent capillary-blood sampling and having various supplies (e.g., test strips, control solutions, and alcohol swabs) to hand. CGMs can essentially eliminate the need for regular fingerstick tests, the long-standing only way to check blood sugar levels. Unlike the FreeStyle Libre, Dexcom sensors only last seven days, necessitating the use of an extra sensor or two every month. We do not endorse non-Cleveland Clinic products or services. Many people do just that. But in March 2018, the FDA approved Medtronics Guardian Connect, the companys first stand-alone CGM in more than a decade. As of 2021, there are four major players we think are worth your consideration. One feature that stands out with The Guardian is the "predictive" alerts you can get about your sugar. It takes time to learn how to use CGM, but it can help you more easily manage your health. Each G6 sensor is labeled to be worn on the abdomen for up to 10 days before needing replacement. Many companies have promoted medtech concepts that they believe could someday revolutionize the way we manage this condition. The app also has audio alerts for glucose levels that are too high or too low.10 The G5 Mobile system consists of a sensor and applicator, a transmitter, and a display device. The Dexcom G6 is the only CGM on the market, aside from the FreeStyle Libre, that can obtain accurate readings even when the patient is taking acetaminophen.11 Further, the G6 is unique because it is FDA-permitted to make diabetes treatment decisions without the use of confirmatory finger-sticks or calibration; however, if the glucose alerts and readings do not match the patients symptoms, a blood glucose meter is required to make treatment decisions.15 Dexcom G6 has been proven to help patients in lowering their HbA1c and in reducing hypoglycemic incidents.1111, Regarding cost, Dexcom monitors are more expensive than the FreeStyle Libre monitor; the three parts to the Dexcom monitorsthe receiver, sensors, and transmitterall have separate costs. 9500 Euclid Avenue, Cleveland, Ohio 44195 |, (https://www.diabetes.org/diabetes/device-technology), (https://www.merckmanuals.com/home/hormonal-and-metabolic-disorders/diabetes-mellitus-dm-and-disorders-of-blood-sugar-metabolism/diabetes-mellitus-dm), (https://www.niddk.nih.gov/health-information/diabetes/overview/managing-diabetes/continuous-glucose-monitoring), Visitation, mask requirements and COVID-19 information. "By placing a sensor on your arm, you can track your glucose constantly through the day and develop your understanding of what makes your sugar levels go up and down. In January 2017, the Center for Medicare and Medicaid Services (CMS) for the first time signed off on the Dexcom CGM as a therapeutic tool because its been FDA cleared to be accurate enough to make insulin dosing and treatment decisions and that meant it was eligible for Medicare coverage. This meter is recommended by Fenichel and waspreviously recommended by Dr. Nate Favini, medical lead of Forward. For example, a fingerstick check may give you peace of mind if your CGM device shows rising or falling numbers, but you feel OK. Call your provider if you have any symptoms youre worried about. There are various monitors available, and they are the focus of this article. Last reviewed by a Cleveland Clinic medical professional on 07/07/2021. A healthcare provider will insert the sensor, and then you place the transmitter above that. A Continuous Glucose Monitoring system, also called CGM, is a way to measure blood sugar for people with diabetes. Dexcoms second monitor is also their most popular, the G5 Mobile. While the base hardware for CGMs (transmitters and receivers) do not need to be replaced often, the costs of the disposable sensors and implant procedures can quickly add up. Seek medical attention when appropriate or contact Abbott at 855-632-8658 or FreeStyleLibre.us for safety info. By contrast, SMBG produces approximately four to seven measurements daily and requires a large commitment from patients to carry out the measurements themselves. Over time, good management of glucose greatly helps people with diabetes stay healthy and prevent complications of the disease. It is also the only monitor that issues predictive alerts of impending highs or lows 10 to 60 minutes beforehand.15 Such unique features come at a cost, however, making Guardian Connect the priciest among the CGMs. Instead, users must manually swipe the handheld receiver or smartphone app over the sensor to get glucose readings. Patients and their physicians are able to assess patterns in glucose fluctuations, which helps them to make informed decisions about nutrition, physical activity, and medication. CGMs automated, always-on setup may give you more freedom, flexibility and peace of mind. People with diabetes need to give themselves insulin regularly to keep blood sugar levels steady. You can regularly check your blood glucose levels using a fingerstick blood check and a blood glucose monitor. Guardian Connects big selling point in keeping with the product name is protection. Also, the glucose reading is not continuous, like other CGMs; instead, the reader has to scan the sensor in a quick second for an accurate and current glucose reading. Generally, the monitor itself consists of a sensor that .
