Thousands unaware they have diabetes could be diagnosed at A&E, says study

Research by NHS trust found simple blood test could help people avoid complications from type 2 diabetes

Thousands of people unaware they have type 2 diabetes could be diagnosed and avoid serious complications if screening was introduced in emergency departments, a study suggests.

The prevalence of the disease has risen dramatically in countries of all income levels in the last three decades, according to the World Health Organization. More than 400 million people have been diagnosed, but millions more are estimated to be in the dark about the fact they have the condition.
