Continuous Glucose Monitoring (CGM) has been recently applied in the clinical diabetic practice. Authors have continued research of glucose variability. In this study, 51 year-old female patient with Type 1 diabetes mellitus (T1DM) was investigated. She has given multiple daily insulin injection (MDI) for long and her recent daily glucose profile was unstable. After applied with FreeStyle Libre, her blood variability was improved with the average glucose from 222 mg/dL to 135 mg/dL, which was partly from her motivation for better diabetic control. Thus, CGM may become a trigger to give beneficial influence for regular lifestyle of the patients
