Abstract

In recent diabetic research and practice, continuous glucose monitoring (CGM) has been prevalent using FreeStyle Libre. Patient is 69-year-old male with type 2 diabetes (T2D) who has Multiple Daily Insulin (MDI). The estimated HbA1c by CGM was 6.4% in May 2024, whereas HbA1c in out clinic was 7.0%. By latest CGM data for 15 days, HbA1c and time in range (TIR) showed 6.4% and 76.7-81.9%, respectively, which were better results than those during half year. Regarding CGM application, glucose variability can be followed in detail by the metrics of TIR, time above range (TAR) and time below range (TBR).
