Well, of course open-minded and humble consultants do exist ! But that fatal combination of ignorance and arrogance is still far too prevalent. Today I had an appointment with a specialist for a health problem which is, as far as I know, not diabetes related. When I handed over my list of medicines, he said, "Oh, you are taking Metformin, you are diabetic." "No", said I, "I am just going in that direction but I want to stop that before it gets any further." "If you are taking Metformin you are diabetic." "Well, my last A1c was 37." "Then you should be taken off Metformin. Metformin is a very dangerous drug with many bad side effects. It should not be used for prophylaxis." "Oh, I thought it was known as a very safe drug." "YOU ARE NOT LISTENING TO ME!!!" End of exchange. Why why why should this man whose specialism has nothing to do with diabetes imagine he knows all about it? Next time we meet I shall give him a printout of the Nice advice that GPs prescribe Metformin to pre-diabetics in the hope of arresting their progress towards diabetes.
