Finally, CGM systems offer more convenience than traditional methods of monitoring blood sugar since they require less frequent finger sticks or visits to the doctor’s office for testing.

How Does Continuous Glucose Monitoring Work?

Continuous Glucose Monitoring (CGM) is an innovative technology that helps people with diabetes to better manage their blood sugar levels. The technology works by using a small sensor inserted under the skin of the arm or abdomen that measures glucose levels in the interstitial fluid. This sensor is then connected to a transmitter device, which sends real-time data to a monitor or phone app. By constantly monitoring glucose levels, CGM helps people with diabetes better understand their current blood sugar level and make informed decisions about food, exercise, and insulin dosage.

The CGM system includes three main components: the sensor, transmitter, and receiver. The sensor is inserted just beneath the skin and contains a tiny filament that monitors glucose levels from interstitial fluid. It is typically worn for 7-14 days before needing to be replaced. The transmitter is a small device that connects to the sensor and sends data wirelessly via Bluetooth or radio frequency to the receiver, which can be either a dedicated monitor or phone app. Using this data, users can get real-time updates on their glucose levels throughout the day and receive alerts when they’re too high or too low.

CGM provides many benefits for people with diabetes, including improved blood glucose control, fewer hypoglycemic episodes, reduced time spent testing blood sugar with fingersticks, and better awareness of how diet and exercise affect blood sugar levels. It also allows users to make informed decisions about food intake and insulin dosage quickly and accurately.

Types of Continuous Glucose Monitors

Continuous Glucose Monitors (CGM) are medical devices used to measure a person’s blood glucose levels on a continuous basis. These monitors provide real-time data about glucose levels throughout the day, helping to provide better diabetes management.
