I'd also be interested in the answers to this, as I've just had my gallstones appointment with the consultant (the initial consultation) cancelled and been discharged from that hospital, because they suddenly realised I was diabetic! It was a private hospital that takes NHS patients on the Choose n Book referral scheme, my GP said because there is a very slight risk of complications with surgery on people who are diabetic, the private clinic (who can pick and choose their patients) decided not to see me :evil:
