 Continuous glucose monitoring, CGM, has revolutionized diabetes management over the past few decades. It has enabled diabetics to better control their blood sugar levels, leading to improved health outcomes. The most recent developments in CGM technology involve minimally invasive methods such as non-invasive glucose monitoring, NGM, which can provide real-time data about glucose levels without requiring any needle pricks or other invasive procedures. These technologies have already demonstrated promising results in terms of HBA1c reduction, and further research is being conducted to improve upon these advancements.
