Diabetes rates in England reveal a postcode lottery – with some areas hit twice as hard as others and sufferers numbering one in 10.
In Brent, north London, for example, 10.5 per cent have diabetes.
This is almost double the rate in the City of London, which has the lowest rate of 5.5 per cent despite being just eight miles from Brent.
Other areas in a list of the top 10 hotspots are Newham, east London, with 9.9 per cent, Wolverhampton in the West Midlands with 9.6 per cent, and Leicester in the East Midlands with 9.3 per cent.
Experts last night warned the figures are a cause for grave concern.
Barbara Young, chief executive of Diabetes UK, which publishes the findings today, said: “It is truly alarming that there is now somewhere in England where more than one in 10 of the people have diabetes.
“It shows that we are heading at a frightening speed towards a future where diabetes becomes the norm.”
Diabetes is the main cause of blindness among working-age people in Britain, as well as lower limb amputation, kidney failure and stroke. Around 3.8 million people in Britain suffer with Type 1 or Type 2 diabetes, including an estimated 850,000 who have yet to be diagnosed.
Up to seven million people are at high risk of developing Type 2 diabetes and, if current trends continue, about five million will have it by 2025.
