A lesser-known malnutrition-related form of diabetes is designated as the Type-5 diabetes.
The condition, occurring often in young and thin adults, was first reported in Jamaica in 1955, and then defined as J-type diabetes.
In the 1960s, the condition was reported in undernourished populations across India, Pakistan, and parts of sub-Saharan Africa.
While in 1985, WHO recognised the condition as a distinct form of diabetes but it removed the designation in 1999.
Type 5 diabetes is a malnutrition-related diabetes, typically affecting the lean and malnourished teenagers and young adults in low- and middle-income countries.
Insulin injections, as in Type 1 diabetes patients, will not benefit these patients.
It is estimated to affect 20-to-25 million people worldwide, mainly in Asia and Africa.
