For example, the NHS annual spending on DM was £9.8 billion in 2012 with an expected increase to £16.9 billion in the next 25 yr (∼17% of the total NHS budget).

EDITOR – The editorial by Jones, Macklin and Alexander makes several excellent and welcome recommendations regarding better prescribing of metformin. It is a pity then that they advised stopping metformin two days before general anaesthesia when there is no evidence to suggest this is warranted, or even safe. We conducted a search of the Medline database using the keywords “metformin”, “an(a)esthesia”, “an(a)esthetics”, “pre-operative” and “diabetes”. We could find no evidence supporting the unreferenced statement in their editorial.
