"The most insulin resistant patients (Group 3) have the most to gain from the new diagnostics as they are the ones who are now most incorrectly treated", says Professor Leif Groop.
Dr Emily Burns, head of research communications at Diabetes UK told The Guardian that while the research was promising, there was still more digging to be done: "We still need to know more about these subtypes before we can understand what this means for people living with the condition", she said. Three forms were severe and two mild. These patients benefitted most from Metformin and had lower usage of insulin compared to cluster 1 despite being clinically similar to them in many ways.
The charity has also revealed the number of people who have been diagnosed with Type 1 and Type 2 diabetes has increased by more than 2,000 in the county since past year.
Diabetes influences around one of every 11 grown-ups worldwide and expands the risk of heart assault, stroke, blindness, kidney failure and appendage removal. Researchers replicated the findings in three further independent cohorts: the Scania Diabetes Registry (n = 1,466), All New Diabetics in Uppsala (n = 844) and Diabetes Registry Vaasa (n = 3,485).
But it is also campaigning for people at high risk of Type 2 diabetes to be identified and referred to the NHS Diabetes Prevention Programme, which supports people to make changes that could prevent the onset of the condition.
The study, by Lund University Diabetes Center in Sweden and the Institute for Molecular Medicine Finland, took a gander at 14,775 patients including a point by point investigation of their blood. This development was made by the experts from Lund University.
New research suggests that diabetes may actually be five different diseases rather than two separate types as previously thought.
This final cluster sees patients who developed diabetes at significantly older ages than other groups, with the condition taking a milder form in this case.
The researchers analysed certain characteristics - such as body weight, blood sugar control and presence of antibodies - against the likelihood of disease complications and need for insulin. This suggests that more studies are needed to confirm that the anti-diabetic effects observed are exclusively caused by lefluonamide's effect on the insulin receptor.

Eleven months ago, we thought we'd seen the last of Zlatan Ibrahimovic . I don't want to come just because I'm somebody.
They believe the more precise groupings - each genetically distinct - will aid diagnosis, help tailor treatments and lead to precision medicines.
Patients within each cluster demonstrated different kinds of health risks.
The most common was one of the more moderate forms, seen in the elderly and affecting 39-47% of the patients.
The authors noted that more research is needed on the issue.
It's linked to obesity and lifestyle factors, and is where the body doesn't produce enough insulin, or the body doesn't react to insulin.
The third "severe" group were people with auto-immune diabetes corresponding to the original "type-1" diagnosis.
The researchers also want similar studies in China and India with people of different ethnic backgrounds.
Group 4, the mild obesity-related diabetes includes obese patients who fall ill at a relatively young age.
He said that this would lead to more precise diagnosis and treatment of diabetes tailored to individual needs.
