A Distinct New Type of Diabetes Has Officially Been Recognized
ScienceAlert • • health
Key Points:
- In 2025, the International Diabetes Federation (IDF) officially recognized type 5 diabetes, also known as malnutrition-related diabetes mellitus (MRDM), urging global health authorities like the WHO to follow suit.
- Type 5 diabetes primarily affects up to 25 million people worldwide, especially in low- and middle-income countries, and is linked to chronic nutrient deficiencies rather than insulin resistance.
- Unlike other diabetes types, type 5 diabetes involves insulin deficiency with preserved insulin sensitivity, requiring distinct diagnostic criteria and treatment approaches to avoid harmful insulin therapies.
- The IDF has established a working group led by endocrinologist Meredith Hawkins to develop formal diagnostic guidelines, create a global research registry, and train healthcare professionals on managing type 5 diabetes.
- Recognition of type 5 diabetes aims to improve diagnosis, research funding, and treatment, particularly in regions with food insecurity, while addressing a neglected disease that severely impacts vulnerable populations.
