With development of the internet and smartphones, various systems have been introduced to monitor patient blood sugar remotely, and their clinical effect on diabetes management has been analyzed in different patient groups. However, these systems need to be available cost-effectively to many patients for the long term. Also, there is need for a communication platform that can easily identify a patient's blood sugar pattern and provide appropriate counseling and education. In addition, relevant educational contents must be provided so that patients maintain self-care for diabetes. With the rapid increase in diabetes patients, we must continuously develop the field of digital healthcare to efficiently monitor blood sugar and provide effective face-to-face management of these patients.
