Continuous glucose monitoring (CGM) technologies provide real-time insights into glucose levels, revolutionizing diabetes management by enabling timely adjustments in therapy and lifestyle. CGM systems use minimally invasive or non-invasive sensors to continuously track interstitial glucose, delivering alerts for hyperglycemia, hypoglycemia, and glucose trends. Integration with insulin pumps, mobile apps, and cloud-based analytics facilitates personalized therapy adjustments and data-driven decision-making. CGM improves glycemic control, reduces hypoglycemic events, and enhances patient engagement and adherence. By leveraging continuous glucose monitoring, healthcare providers and patients can achieve more precise diabetes management, optimize insulin therapy, and support overall health outcomes.
