Abstract
Both the global prevalence of diabetes and the frequency of natural and man-made disasters are increasing. Of all chronic diseases, the consequences of sudden loss of medical supplies are most serious for those with diabetes, with people living with type 1 diabetes being at risk of death within a few days without insulin. This review considers how to prepare for and respond to sudden reductions in medical supplies to those with diabetes. Recent experiences with the COVID-19 pandemic in India, the war in Ukraine and the war/blockade in the Tigray region of Ethiopia are described, and the importance of prevention, preparedness, response and recovery are discussed. It is hoped that lessons from these and other disasters and ongoing advocacy and other actions may help to mitigate the risks of significant morbidity and mortality for people with diabetes in disaster-impacted regions across the world.
