In our country, glycemic monitoring in diabetics is almost entirely limited to digital puncture. In developed countries, continuous glucose monitoring (CGM) devices have been used, which allow glucose fluctuations to be evaluated throughout the day. Objective: To describe the glucometric findings of patients receiving CGM, as well as the changes it induced in the management of diabetes. Material and Methods:A retrospective study was conducted of 28 patients (9 pediatric and 19 adult) treated in three endocrinology clinics, diagnosed with type 1 or 2 diabetes mellitus (DM), who used real-time or retrospective CGM devices.The variables studied were those reported by the sensors, such as average glucose, times in ranges, daily readings recorded. Results: A correlation was found between the number of daily readings on the sensor and the percentage of time in glucose range (adjusted R=0.51; p...
