You may have a better GP. They are not all the same. And it's not just me saying it. My experience is entirely in line with what Dr Roy Taylor, a leading researcher into Diabetes, wrote in Practical Diabetes:
"It must be recorded that many individuals expressed frustration at the routine manner in which their doctor, nurse or dietitian regarded the diagnosis of type 2 diabetes. This conflicted with the cataclysmic blow which they personally felt. They were told that the diagnosis was clear and therefore the guidelines will be rolled out. Lose some weight and take this metformin. Get used to it."
My DN at the time could accurately be described as utterly incompetent. During one clinic she said that she was going to fine tune my medication and I had to point out to her that I wasn't on any. At the next clinic she repeated the same and I was forced to ask if she ever read her patients' notes. Without batting an eyelid she said she didn't have time for that.
I don't know your GP from Adam but my experience, the experience of many people on this forum, the experience of other HCPs and the report by the all party parliamentary committee on diabetes care is that far too many GPs simply follow a routine tick box approach and not the individual targeted care that they are supposed to do.
I'm pleased that you think you have one such GP. Not everyone does by any means.
