Summary
- Eminent diabetes researcher Dr. Chittaranjan Yajnik describes a new form of diabetes, Type-5
- Type-5 diabetes predominantly affects undernourished and low-BMI individuals
- International consensus meeting in 2025 proposed the term 'Type-5 diabetes'

In November 2025, eminent diabetes researcher Dr. Chittaranjan Yajnik from KEM Hospital, Pune, has described a newly recognized form of diabetes, called Type-5 diabetes. This unusual form of diabetes is predominantly affecting undernourished populations, particularly those from socio-economically deprived communities and rural areas.
According to Dr. Yajnik, Type-5 diabetes poses novel challenges compared to the more common Type-2 diabetes. Unlike Type-2, which is associated with obesity and high BMI, Type-5 diabetes is seen in individuals with low BMI and insulin deficiency. An international consensus meeting held in Vellore, India, in January 2025 proposed the term 'Type-5 diabetes' to distinguish it from Type-1 and Type-2 diabetes, as well as other rare genetic and secondary forms.
