From the BBC: Labelling people as having pre-diabetes is "unhelpful and unnecessary", researchers claim. The definition, given to people on the "cusp" of type 2 diabetes, has no clinical worth, a joint UK-US team argues. There is no proven benefit of prescribing drugs as many will not develop diabetes, the researchers write in the British Medical Journal. But a charity said being identified as being at high risk was helpful. It offered the chance to reduce risk by eating a healthy diet and being physically active, said Diabetes UK. People with pre-diabetes have no symptoms of ill health, but their blood sugar levels are at the high end of the normal range. The term is not recognised by the World Health Organization but has been used in many scientific papers.
