They noted this method of clustering diabetes type could be easily applied to patients in clinic and trials alike.
The mild diabetes related to age, which was most common (affecting between 39 and 47 percent of patients).
Britain's worst diabetes town is Bradford, where one in ten people have the disease - placing incredible strain on health care resources - and the lowest level is in Richmond, West London, said Diabetes UK.
Cluster 2 - severe insulin-deficient diabetes patients were similar to those in cluster 1, but the immune system was not at fault.
Severe insulin-resistant diabetes patients, generally overweight and producing insulin, which their body was no longer responsive to. Their bodies make insulin but don't use it the right way.
Dr Emily Burns, from Diabetes UK, said understanding the diseases could help "customize medications and conceivably lessen the risk of diabetes-related difficulties later on". People with this type were overweight, and while still making insulin, their bodies weren't responding to it.
Emma Ahlqvist, Ph.D., from Lund University in Sweden, and colleagues used data from the Swedish All New Diabetics in Scania cohort to do data-driven, cluster analysis in 8,980 patients with newly diagnosed diabetes.More news: Ukraine closes schools to save gas as Russian Federation keeps pipelines closed
Group 2 had a higher risk of blindness while bunch 3 had the most serious risk of kidney sickness, so a few bunches may profit by upgraded screening.
Cluster 2: This category is labelled "severe insulin-deficient diabetes", affecting 17.5 per cent of patients, As above, those in this bracket tend to be young and at a healthy weight, but it's not thought that the immune system is implicated in the development of diabetes.
Almost 15,000 patients in Sweden and Finland were monitored for a variety of factors, including age at diagnosis, body-mass index, long-term glycemic control, functioning of insulin production in the pancreas, insulin resistance, the detection of auto-antibodies, genetic analyses, disease progression, complications, and treatment success. These patients were at a higher risk of developing kidney disease.
But now a major project in Sweden and Finland has found type two diabetes should actually be categorised as four different diseases.
And each comes with significantly different characteristics and risk of complications, they found. "It would be reasonable to target individuals in these clusters with intensified treatment", they wrote.
A new analysis published today in The Lancet Diabetes and Endocrinology indicates researchers were able to distinguish 5 new subgroups of patients with adult-onset diabetes, representing a first step toward precision medicine. Further larger studies with diverse populations may be necessary before these results can be generalized.
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.
