Dispelling common misconception that Type-1 diabetes is predominantly a "disease of childhood", a new study says that adults are as likely to develop the condition as children.

The scientists, whose work is published in The Lancet Diabetes & Endocrinology journal, found it takes a year on average for adults with type 1 diabetes to be diagnosed correctly.

Dr Richard Oram, a senior lecturer at the University of Exeter and consultant physician, said: "Diabetes textbooks for doctors say that type 1 diabetes is a childhood illness".

'Failure to diagnose late-onset type 1 diabetes can have serious consequences because these patients rapidly develop insulin dependency'.

But they said doctors find it very hard to pick them out because type 2 diabetes is becoming so common, mainly because of the United Kingdom obesity crisis.

Dr Emily Burns of Diabetes UK said: 'While more research is needed to understand the realities of misdiagnosis, we'd ask healthcare professionals to have this insight in mind - don't rule out type 1 diabetes after the age of 30'.

On average, it takes a year for those with type 1 diabetes who have been misdiagnosed with type 2 to receive the insulin treatment they need, putting them at risk of experiencing potentially fatal diabetic ketoacidosis.

"Failure to recognise that the diabetes is type 1 rather than type 2 and give appropriate insulin treatment can be risky".

The study used a novel genetic analysis to identify Type-1 diabetes in adults.

Type 2 diabetes, on the other hand, is strongly linked to lifestyle and obesity, and is usually caused when someone becomes resistant to insulin. This highlights that type 1 diabetes is often not considered as a diagnosis in adults. The diagnosis of type 1 diabetes in middle and old age is very hard ... Type 2 accounts for 96 per cent of diabetes cases between the ages of 31 and 60, the research shows.

Despite this, type 1 diabetes is often regarded as a "disease of childhood", meaning that many sufferers are initially thought to have type 2 diabetes at first, and do not receive treatment with insulin to control blood sugar levels.

The report notes that among those to be misdiagnosed is British Prime Minister Theresa May, who developed type 1 diabetes in her 50s.
