Type 5 Diabetes

Context

At the recently concluded World Diabetes Congress in Bangkok, the International Diabetes Federation officially recognised Type 5 diabetes as a new condition.

?About Malnutrition-Related Diabetes (Type 5 Diabetes):

  • Type 5 diabetes is a malnutrition-related diabetes, typically affecting lean and malnourished teenagers and young adults in low- and middle-income countries.
    • Today, there are an estimated 20-25 million people worldwide, mainly in Asia and Africa, who are afflicted by this disease.
  • It is characterized by a significant deficiency in insulin secretion, distinguishing it from Type 1 (autoimmune destruction of beta cells) and Type 2 (insulin resistance) diabetes.
  • Insulin therapy, effective in Type 1 diabetes, can be harmful in Type 5 due to the risk of hypoglycemia.?
  • First identified in Jamaica in 1955 as J-type diabetes, the condition was recognized by the World Health Organization (WHO) in 1985 but was later removed from classification in 1999 due to insufficient evidence.
  • Recent studies have provided substantial evidence leading to its reclassification as Type 5 diabetes.?
