A Long-Ignored Crisis: Type 5 Diabetes Officially Recognized

After decades of being overlooked and frequently misdiagnosed, Type 5 diabetes has finally received official recognition from the International Diabetes Federation (IDF) as a distinct form of the disease. This acknowledgment marks a crucial step forward in addressing a condition that disproportionately affects malnourished teenagers and young adults in low- and middle-income countries.

Understanding Type 5 Diabetes: A Distinct Profile

Unlike Type 2 diabetes, which stems from insulin resistance, Type 5 diabetes is characterized by a decrease in insulin production directly linked to malnutrition. The pancreas struggles to produce sufficient insulin, leading to impaired glucose regulation. This contrasts sharply with Type 1 diabetes, an autoimmune condition where the body attacks insulin-producing cells.

professor Peter Schwarz, former President of the IDF, initially championed the term “Type 5” earlier this year. The official recognition occurred on April 7th at the 75th World Diabetes Congress in Bangkok, Thailand, solidifying its place in the medical lexicon.

Ancient Context: From “Diabetes Type J” to Official Recognition

While the official designation is new, the disease itself is not. The earliest reports date back to Jamaica in 1955,initially termed “Diabetes type J.” In 1985, the World Health Association (WHO) classified it as malnutrition-related diabetes mellitus. Though, this classification was retracted in 1999 due to a perceived lack of conclusive evidence linking it directly to malnutrition – a connection that is now central to the understanding of Type 5 diabetes.

Global Prevalence and Impact

Type 5 diabetes is primarily observed in countries within the southern hemisphere, including India, Sri Lanka, Bangladesh, Uganda, Ethiopia, Rwanda, and Korea. Current estimates suggest that approximately 25 million individuals worldwide are affected by this condition. The recognition of Type 5 diabetes is expected to spur further research and targeted interventions in these regions.

The renewed focus on Type 5 diabetes stems from recent research highlighting the profound impact of nutritional deficiencies on pancreatic advancement and insulin function, particularly in individuals who experienced malnutrition during childhood and early adulthood. This research underscores the critical role of early nutrition in preventing this specific form of diabetes.

Key Characteristics of Type 5 Diabetes

According to Dr. Niral Thomas, a member of the Type 5 diabetes working group, this unique form of diabetes, particularly prevalent in individuals of Asian Indian descent, shows no evidence of autoimmune or genetic origins. Individuals with Type 5 diabetes typically exhibit a significantly lower body mass index (BMI), often below 18.5 kg/m², indicating a state of undernourishment.

Further distinguishing features include:

• Significantly reduced insulin secretion compared to Type 2 diabetes.
• Lower body fat percentage compared to Type 2 diabetes cases.
• Deficiencies in protein, fiber, and essential micronutrient intake.

These characteristics highlight the critical role of nutritional interventions in managing and possibly preventing Type 5 diabetes. Public health initiatives focused on improving nutrition in vulnerable populations are essential to combatting this emerging health challenge. According to the World Food Program, nearly 828 million people globally face hunger, underscoring the urgency of addressing malnutrition as a key factor in the development of Type 5 diabetes.
