Abstract

Diabetes has been studied and managed internationally by the American Diabetes Association (ADA), the European Association for the Study of Diabetes (EASD), the Japan Diabetes Association (JDA), and so on. The International Diabetes Federation (IDF) proposed “type 5 diabetes (T5D)” in April 2025. T5D mainly develops due to chronic malnutrition during childhood, particularly in low-income countries, affecting an estimated 20 to 25 million people. It shows low body weight and insulin deficiency, previously known as malnutrition-related diabetes (MNRD). Its novel perspective typing will contribute to more awareness and discussion for medicine, education, public health, the economy, and social factors such as poverty and nutritional disparities.
