Continuous blood glucose monitoring techniques: A Review

Abstract

Continuous Glucose Monitoring (CGM) is recommended over conventional self-blood glucose monitoring because Continuous Blood Glucose Monitoring has become very essential in Diabetes management. Diabetes / Diabetes mellitus is a chronic disease that has become a major health issue globally. Mainly, Type 1 Diabetes and Type 2 Diabetes need Continuous Glucose Monitoring for disease management. The minimally invasive method is the main technique used for Continuous Glucose Monitoring in the present day. Continuous Glucose Monitoring using non-invasive methods is an emerging field nowadays because of the difficulties related to the existing Continuous Glucose Monitoring methods/systems. This review article presents the importance of Continuous Glucose Monitoring, the existing techniques of Continuous Glucose Monitoring and their new approaches, the difficulties and drawbacks related to them, and the emerging techniques of Continuous Glucose Monitoring. The conclusion states that there is an enormous need for a wearable, inexpensive, non-invasive Continuous Glucose Monitoring approach that has the same accuracy level as the invasive procedures to be used in Diabetes management.
