But it’s a subjective word, just like saying someone is pretty or handsome. So if a doctor writes controlled then in his opinion it is controlled. When you write you are controlled it is in your opinion controlled.
So example say you go into court and go I am a controlled diabetic, they might want proof or not. So you present copies of say clarity reports that say you are 70% in the generally accepted target range of 70-180, and less than 4% under 70. I believe that is the latest bandied about numbers.
And you take a copy of this page with you to show
Or you say I have an A1C of 6.9% and the aim is to be under 7% so I am considered controlled and you bring in something like this.
In both these cases it would benefit you to have several documents from well known sources like ADA, something widely known and accepted. I don’t think wedmd would cut it, but it was easy to find.
But if you need something from a doctor that says you are controlled it would still end up being from his viewpoint that he is signing too. Then you would need to talk him into believing you are controlled for him to be able to write it.
And if you are talking about not getting along with your doctor, yea switch doctors. But you won’t know until you see the doctor if whether you will get along with him or if he is even nice. You can try the internet to see if people have written anything about them. I know the endo I hated had several people not like him and even my GP said he had a lot of people not like him. They won’t always tell you but maybe counter people might etc.
Unfortunately seeing a doctor is trial and error.
