Type 2 diabetes mellitus (T2DM) is rising globally, with low- and middle-income countries, including South Africa, bearing a disproportionate burden. This chapter explores the role of digital health tools such as mobile health (mHealth), wearable technologies, and artificial intelligence in supporting T2DM prevention and management. It critically examines how these innovations promote education, behaviour change, and self-management in under-resourced settings. The chapter highlights that while digital tools offer scalable solutions for diabetes care, their success depends on equitable access, cultural relevance, and integration into primary healthcare. Challenges such as the digital divide, data privacy, and weak system alignment must be addressed. Community engagement enhances trust and long-term use. Looking forward, digital health can transform care if supported by context-specific research, inclusive design, and enabling policies. A hybrid model—blending innovation with person-centred care—is essential for sustainable, accessible diabetes management rooted in local realities.
