Type-2 diabetes signs 'detectable years before diagnosis'
The warning signs of type-2 diabetes may be detectable 20 years before the disease is diagnosed, researchers say.
Elevated fasting blood sugar levels and insulin resistance were seen in people years before they developed pre-diabetes, often a pre-cursor to type-2, a study found.
The findings suggest interventions to stop the disease in its tracks should begin far earlier in life, authors say.
Another study found type-1 diabetes may be misdiagnosed after the age of 30.
