This was likely your A1C, or a metric of the last three months or so of your sugar levels.

Just because you feel healthy doesn’t necessarily mean you are healthy. You may have, for example, a pancreas condition. Or it may be nothing at all, and just something to track, which is why you never base any medical decisions off a single test.

Your last sentence is nonsense. People can provide exceptional (and correct) advice without necessarily following it themselves, and for all you know this nurse has spent the last year actively trying to improve their health.

It's strictly a question of his likelihood P for developing diabetes. If his P is the same as that of other people with lower A1C, then "prediabetes" is nonsense.
