Around one in eight new cases of diabetes linked to obesity is now in younger people, research suggests.

Experts found that those in the 18 to 40 age group accounted for 12.5% of cases of Type 2 diabetes diagnosed in 2017 in the UK.

This is almost a third higher than the 9.5% in 2000, according to analysis of the health records of 370,854 UK patients by experts at the University of Leicester and Melbourne University.

The research also found that nearly three quarters of them were obese, compared with fewer than half of those diagnosed with Type 2 in their 70s.

And 58% of the under-40s had dangerously high blood sugar levels compared with 34% in the older age bracket.

Diabetes rates similarly went up among those aged 41 to 50 over the 17-year study period, from 14% to 17.5% of this age group.

Since 1996, the number of people diagnosed with diabetes in the UK has risen from 1.4 million to 3.5 million, according to the charity Diabetes UK.

The figure rises to more than four million when the number of people likely to be living with undiagnosed diabetes is taken into account.

The authors of the latest study suggested that more younger people should be prescribed statins to help control their risk of having a heart attack.

They said: “Young people with (Type 2) have a higher cardiovascular risk factor burden.

“While cardiovascular morbidity and mortality risks have declined substantially over the years for older people with (Type 2), they remain unchanged for younger people.

“Young-onset diabetes has a more aggressive phenotype compared to older-onset diabetes.

“More intense strategies are required to improve longer term cardiovascular and mortality outcomes in this population.”

Dr Faye Riley, of Diabetes UK, said: “This research stresses the particularly dangerous nature of the condition in those diagnosed at a younger age.”
