Scandinavian research indicates there may not be simply two diabetic conditions (Type 1 and Type 2). Patients can be separated into five distinct clusters or sub-types, each with distinct symptoms, complications and possible treatments.
- Cluster 1: Severe Autoimmune Diabetes, broadly the same as the Type 1.
- Cluster 2: Severe Insulin-Deficient Diabetes, similar to above but where the immune system is not at fault.)
- Cluster 3: Severe Insulin-Resistant Diabetes, where patients are overweight and making insulin but their bodies no longer respond to it.
- Cluster 4: Mild Obesity-Related Diabetes, where people are overweight but metabolically more similar to normal.
- Cluster 5: Mild Age-Related Diabetes, where patients develop symptoms when older and the disease is typically milder.
Treating people in distinct groups differently might yield better outcomes, along the lines of personalised medicine.

Prevalence and Cost Trends

“…diabetes prescribing costs £1 billion per year, but it is estimated that the total cost to the NHS is over £10 billion per year… ”. Robin Hewings: Diabetes UK.
