Abstract

Diabetes mellitus represents a major global public health challenge, with rising prevalence, substantial morbidity, 
and escalating health system costs. Digital health interventions (DHIs) have emerged as promising tools to 
support diabetes prevention, self-management, and long-term care through the use of telemedicine, mobile health 
applications, digital therapeutics, wearable devices, remote monitoring, and decision-support systems. This 
narrative review synthesizes current evidence on the scope, classification, and effectiveness of digital health 
interventions for diabetes management. It examines conceptual frameworks underpinning DHIs, key intervention 
modalities, and their impact on clinical outcomes such as glycemic control, hypoglycemia reduction, 
cardiometabolic risk, body weight, and patient-reported outcomes. The review further examines implementation 
considerations, including health system integration, reimbursement models, equity, digital literacy, data privacy, 
and interoperability. Overall, the evidence suggests that digital health interventions can improve glycemic 
outcomes, enhance patient engagement, and support lifestyle modification, particularly when interventions are 
multifaceted and integrated into routine care. However, heterogeneity in intervention design, methodological 
limitations, and inequities in access remain significant challenges. Future research should focus on long-term 
effectiveness, implementation in underserved populations, and the development of scalable, interoperable, and 
patient-centered digital solutions to strengthen diabetes care across diverse settings.
