Because of the penetration of this condition is increasing all over the world, the availability of highly advanced tools for monitoring is indispensable. These devices are the Continuous Glucose Monitoring (CGM) systems, which are suitable solution for individual and optimal solution of management of diabetes. In this paper we gave a summary study of the meaning, aims and available methods of CGM systems. References [1] A. Fonyó and E. Ligeti.
