Basics and applications of continuous glucose monitoring (CGM)

Continuous Glucose Monitoring (CGM) is rapidly replacing Self-Monitoring of Blood Glucose (SMBG) due to its enhanced accuracy and ease of use.CGM systems, all equipped with sensors, assess glucose levels in the subcutaneous fluid over 6-14 days, with some implanted devices offering six-month monitoring.They display glucose levels instantly or upon scanning and include features like warnings, alarms, and trend data, requiring intensive training for effective use.In summary, CGM systems provide comprehensive blood sugar snapshots, empowering patients to manage glucose levels effectively, reducing hypoglycemic and hyperglycemic episodes.Regular CGM use significantly lowers glycated hemoglobin (HbA1c) and hypoglycemic events, revolutionizing diabetes management.
