Vulnerabilities to Mitigate the Newly Recognized Type-5 Diabetes in Low-resource Settings: A Review on Bangladesh Perspective and a Call for Global Action

Type-5 diabetes (T5D), a recently identified malnutrition-related diabetes subtype, is a serious public health concern for both world health and Bangladesh, where high rates of undernutrition coexist with a rapidly increasing diabetes epidemic. T5D disproportionately impacts low- and middle-income nations. Bangladesh is a hotspot due to the dual burden of undernutrition and diabetes, with high rates of childhood stunting (24%), wasting (11%), and adult diabetes prevalence (13.2%). This review attempts to identify T5D mitigation vulnerabilities in Bangladesh, a representative sample of low-resource nations, including resource limitations, socioeconomic inequalities, dietary attitudes and practices, awareness gaps, cultural obstacles, and natural disaster concerns. Key constraints include widespread economic hardship, which restricts access to healthy food and healthcare; dietary shifts toward processed foods, which intensify micronutrient deficiencies; and suboptimal child feeding practices. Weaknesses in the healthcare system, such as insufficient resources, diagnostic restrictions, rural-urban inequities, and a scarcity of skilled professionals, impede early identification and treatment. Gender disparities and domestic violence increase the hazards, since starving women have intergenerational metabolic effects on their children. Furthermore, frequent natural catastrophes interrupt food security, exacerbating malnutrition-diabetes relationships. Multisectoral initiatives are required for effective mitigation of T5D, including scaling up nutrition interventions, enhancing basic healthcare, and establishing social protection programs. Policy changes must include T5D in national diabetic standards, and community-based awareness initiatives must remove cultural stigmas. Without measures, T5D will worsen health disparities in low-income countries such as Bangladesh, highlighting the need for global attention and customized public health initiatives to prevent the malnutrition-based T5D.
