Blood glucose levels are typically measured with a finger prick at a particular instant in time. Using a CGM enables the presentation of blood glucose patterns over time. While some Continuous Glucose Monitoring (CGM) Devices don't require user calibration, others do need to be frequently calibrated by users using conventional blood glucose measurements. CGM is a widely used technology that has been demonstrated to be advantageous for diabetics. Studies have shown good results such as a shorter duration of hypoglycemia or a lower level of glycated haemoglobin. Little and contradictory evidence about the effectiveness of continuous glucose monitoring devices in children, adults, or people with poorly managed diabetes, according to a Cochrane systematic review.
