So spoke to the GP today who is furious at the heart association nurse. Not very helpful she said to scare patients witless.
She said given how high it is it could be a rogue result. It could be that I have a problem and I probably will end up on statins at some point but in need to stop blaming myself as unless I'm secretly binge eating soft cheese my diet is not likely to be causing it.
She can see why I'm now panicking but they need to repeat the test in six weeks time and if it's still high she will consult with the cholesterol specialist and take it from there. I have no familial history and so there might be a reason for it. My cholesterol has been high for about 15 years. In 2015 it was 6.8 and at that point I was running 20k a week.
She said it's a complicated equation that needs to be thought about. Despite recent events I am one of the healthiest patients she has and we shouldn't rush in to anything.
