IMPACT OF DIABETES MELLITUS ON WORKPLACE PRODUCTIVITY IN THE UNITED KINGDOM: A LITERATURE REVIEW

ABSTRACT Introduction: Diabetes mellitus (DM) is a chronic metabolic disorder with rising prevalence globally and in the United Kingdom. Among working-age adults, diabetes has become a significant public health concern due to its implications on physical health, mental wellbeing, and overall economic productivity. Objective: To explore and synthesize existing literature on the impact of diabetes mellitus on workplace productivity in the UK, highlighting the associated challenges, economic costs, and strategies for mitigating its effects in occupational settings. Methodology: This narrative review synthesizes findings from peer-reviewed journal articles, government reports, and relevant grey literature published between 2016 and 2025, focusing on the prevalence of diabetes mellitus and its impact on workplace productivity in the United Kingdom. Results: The literature reveals that diabetes contributes to increased absenteeism, presenteeism, early retirement, workplace accidents, and mental health challenges. It imposes both direct and indirect economic costs exceeding £10 billion annually. These effects are particularly pronounced among individuals with poorly controlled diabetes or diabetes-related complications. Flexible workplace policies, integrated healthcare support, and employer-led health promotion programs are associated with improved outcomes. Conclusion: Diabetes mellitus poses a substantial threat to workforce productivity in the UK. Addressing this issue requires a multi-sectoral approach involving healthcare systems, employers, and policymakers. Early intervention, supportive work environments, and improved access to both physical and mental health care can mitigate the productivity losses associated with diabetes.
