The UK guidelines currently focus on the total chol/HDL ratio. For context, US guidelines focus on LDL levels. Either way, you're a bit high on both.
Total chol = LDL + HDL + 0.5 * trigs. Your HDL levels are just fine and in any case, changing HDL can be tough. Your trigs are fine. So from either the US or UK points of view, the evident thing to focus on is reducing LDL.
Dietary changes can have an impact on LDL (eg eating less saturated fat). Statins have a bigger impact. So yr doc will probably want to have a statin conversation.
This is the rough little tool recommended in the UK guidelines for working out your CV, stroke etc risk:
https://qrisk.org/three/index.php It's probably worth playing around with it a bit as prep for the doc conversation. You'll quickly see that "diabetes" is just a yes/no switch - no provision for exploring risk for different HbA1c levels etc - and the rough doubling in risk you might see from turning it on is surely far too crude.
But in any case, depending on whether you have any contributing factors, you'll probably find that yr risk levels aren't way high, in which case there's probably no need to make snap decisions on statins etc.
