Guardian REAL-Time glucose monitor. The small glucose sensor is inserted under the skin. The transmitter transmits glucose readings to the monitor.
A continuous glucose monitor is a device that measures glucose levels continuously, 24 hours a day. The glucose monitor may help you understand how food, exercise, and medication impact your glucose levels, so you can better manage your diabetes. Many continuous glucose monitors also include alarms to indicate when your glucose levels have exceeded or fallen below your pre-set levels.
Depending on the type of monitor, a small glucose-sensing device (or sensor) is inserted just under the skin on your stomach. The sensor measures glucose levels every few seconds and sends the information via a wireless transmitter to a monitor that can be worn on your belt or in a pocket.
A continuous glucose monitor can help you become aware of your glucose levels and how they change based on food intake, exercise, and medication.
