Rates of stroke and kidney failure in people with diabetes have reached record levels, according to a new analysis.
The conditions - which are complications of diabetes - jumped to their highest level in 2009/10, Diabetes UK said.
More than 16,000 people with diabetes in England are estimated to have had a stroke in 2009/10, based on an incidence rate of 0.69%.
This represents a 57% rise since 2006/07.
More than 8,800 people with diabetes are also thought to have suffered kidney failure in 2009/10, based on an incidence rate of 0.38%. This is 31% higher than in 2006/07.
In the UK, there are currently 2.9 million people diagnosed with Type 1 or 2 diabetes.
An estimated 850,000 more people have Type 2 diabetes - which is linked to unhealthy lifestyles and obesity - but do not know it.
By 2025 it is estimated that five million people will have diabetes.
Barbara Young, chief executive of Diabetes UK, said: “These figures are a reminder that all people with diabetes should have these checks every year, as this is the simplest and most effective way of reducing risk of complications such as stroke and kidney failure.”
