Eren Erdal , Ongen Yasemin Denkboy , Demirbas Ozgecan , Tarim Omer

Introduction: Reduction in glycemic variability and HbA1c levels are achieved by the use of continuous glucose measurement systems (CGM) in the patient with Type 1 diabetes mellitus (T1DM). Intermittently viewed CGM (iCGM) using flash technology have been used increasingly by diabetics and their families because of practicality. Evaluating of ambulatory glucose profiles (AGP) is very important in the management of T1DM.Aim and Me...
