Understanding Type 5 Diabetes: A New Diagnosis in Diabetes Care

Core Event: Recognition of Type 5 Diabetes
Type 5 diabetes, a newly recognized form of diabetes, was officially acknowledged by the International Diabetes Federation in 2025. This condition is estimated to affect up to 25 million individuals globally. Unlike Type 1 and Type 2 diabetes, which arise from autoimmune destruction and insulin resistance respectively, Type 5 diabetes is primarily caused by chronic undernutrition during early life, leading to inadequate insulin production.
Key Differences from Other Diabetes Types
Dr. Ken Berry, a family physician, explains that Type 5 diabetes differs fundamentally from Type 1 and Type 2 diabetes. In Type 1, the immune system attacks pancreatic beta cells, while Type 2 involves insulin resistance due to obesity. Type 5 diabetes, however, results from underdevelopment of the pancreas due to early nutritional deficits, leading to a defect in insulin production rather than resistance.
At-Risk Populations
Type 5 diabetes is more prevalent among individuals who experienced significant malnutrition during childhood or adolescence. Dr. Yoon Kook Kim notes that it is particularly common in low- and middle-income countries, especially in regions of Asia and Africa. Additionally, marginalized or food-insecure populations in higher-income countries may also be affected, although this is less documented.
Symptoms and Diagnosis
Symptoms of Type 5 diabetes are similar to those of Type 1 and Type 2 diabetes, including increased thirst, frequent urination, fatigue, and weight loss. However, individuals with Type 5 diabetes may present as underweight and have a history of poor early nutrition. Misdiagnosis is common, as many patients have previously been classified as Type 1 or Type 2, which can lead to inappropriate treatment.
Importance of Early Detection
Early evaluation is crucial for individuals with a history of undernutrition or those who have not responded well to typical diabetes treatments. Dr. Berry emphasizes that correct diagnosis is essential for tailoring treatment, as misclassification can result in overtreatment or undertreatment.
Treatment Approaches
Treatment for Type 5 diabetes is still evolving, with formal guidelines currently in development. Initial treatment strategies may resemble those for Type 1 diabetes, focusing on insulin therapy due to the underproduction of insulin. Dr. Kim suggests that addressing nutritional deficits and carefully tailoring glucose-lowering therapies are vital. This includes improving protein intake and correcting micronutrient deficiencies.
Future Directions
The International Diabetes Federation has initiated a work group dedicated to Type 5 diabetes, aiming to enhance awareness and develop targeted treatment options. As research progresses, there is hope for more effective management strategies tailored to the unique needs of individuals with Type 5 diabetes.
