I've had a fair bit of experience bringing new info to Doctors (12 years).
I was told I was 'in the diabetic range' and sent home with metformin 1000mg SR bd.
What I would have liked my GP to tell me is that diet and exercise (where possible) is the most effective along with self management. The GPs and nurses dismiss our self testing as a 'snapshot reading.'
A very good point.
I have (IMHO) a good GP, who's given me some time to discuss my condition. But even he has only done so because I've asked him questions during several appointments for peripheral issues, subsequent to my diagnosis in September this year. I'd like to have seen an immediate offer - that should be made to ALL who are newly-diagnosed - of an urgent (say) 20 min consultation with the GP, to explain the issues involved, the symptoms I can expect to have, medication(s) that might be tried and those I might need now, and ways I might better manage my new, chronic, life-threatening, illness, followed by a rigorous case-management regime.
As it was, I too was given 1000mg Metformin and sent on my way. Nothing about what happens next, prognosis, or anything. The DN I made my own appointment for, 3 weeks later, really wasn't helpful. She wondered aloud if '1000mg was really enough' but didn't want to follow that up ('Oh well, doctor must know best' was her next remark), and seemed more concerned about what I'd done in the previous year to 'cause the problem' (weight gain, she surmised) than what I should be doing in the future.
The current treatment regime is too hit-and-miss: It seems to depend on how clued-up (or vocal) you are, or decide you want to be, whether you're well enough to push your case, and whether you have a GP/DN who can make the grade. That's an appalling approach to such a serious problem that's widespread and growing. I can't see why a transparent and progressive programme of treatment and assistance cannot be devised which must then be applied to all diabetics, with GPs etc. being monitored for overall compliance.
In terms of efficiencies, it doesn't take a genius to work out if ALL diabetics who want it (and that's the vast majority, I think) can be given help to help themselves, the NHS is in a win-win situation. If it doesn't, it's storing up a time-bomb of cost, let alone in human misery and premature demise, in the next few decades to come.
