The basis of telemedicine is the use of modern technologies that are used in everyday life, but also in diabetes management. Technology are applied not only in insulin administration and glycemic monitoring, but also in the management of lifestyle interventions such as healthy eating and physical activity. Telemedicine in diabetes can significantly expand our options for the care of patients with diabetes and its complications, leading to convincing improvements in diabetes control and self-management of patients with diabetes. The positive effect of telemedicine depends on the correct setup of data transmission and processing, but also on the education of all involved. Telemedicine promotes the involvement of patients as well as other healthcare professionals in diabetes management, improves care coordination and streamlines communication between patients and healthcare professionals.
