Based on the National Health Survey in 2010, almost half a million Singaporeans have diabetes, higher than the global prevalence. Diabetes is associated with a host of complications including heart disease, stroke, kidney failure, blindness and amputation. In 2016, Singapore declared a ‘war on diabetes’ to decrease the incidence of diabetes and its complications. Beyond providing healthcare resources, tackling diabetes requires the shifting of mindsets and changing of habits. The case study illustrates how biopsychosocial factors play a role in the optimal care of a diabetic patient. Self-management, acceptance, empowerment and health literacy are essential components to good diabetic care. System and support factors, as well as excellent communication with healthcare providers, are advocated as strategies to optimise outcome.
