Treatment for millions of people with type 2 diabetes should be more personalised, with greater access to newer medicines, including weight-loss drugs, the healthcare assessment body for England, Wales and Northern Ireland has recommended.
It calls the move "the biggest shake-up" in type 2 diabetes care in a decade.
Offering more people the new drugs will prevent complications such as heart disease, strokes and kidney damage, reduce costs to the NHS and potentially save lives, the National Institute for Health and Care Excellence (NICE) says.
Around 4.6 million people in the UK are diagnosed with diabetes - of these 90% have type 2, with another 1.3 million likely to be undiagnosed.
Having type 2 diabetes means there is too much glucose or sugar in the blood. This makes strokes, heart attacks, heart failure and other health conditions much more of a risk. It is now so common that 10% of the NHS budget goes towards treating it.
