The Continuous Glucose Monitoring (CGM) device is a blood glucose sensor that allows you to assess and measure the level of glucose in the interstitial fluid. It works autonomously, relieving you from constantly monitoring your blood glucose levels. Your blood glucose level is assessed by the sensor placed on your skin, which you can keep in place for up to 14 days. The device comes with a meter that allows you to read information about your blood glucose variability.
However, you may encounter some problems with your sensor. Indeed, you must be meticulous when choosing its location should you place it on moles, scars or tattoos, sensors can slip. The adhesion of a CGM sensor is variable depending on cosmetics applied to the skin, skin type and the moisture of the skin or a persons hairiness. This means that you often have to place the sensor behind your arm or readjust it.
