Should I worry about these cholesterol results?

[Valleyofthedollymix]

So just had some blood tests as I'm thinking of HRT. I got a text telling me my cholesterol was high so I emailed for a proper breakdown.
Total cholesterol: 6
HDL: 1.8
Non HDL: 4.2
Ratio: 3.3

So my total is one over what the maximum (5) and my bad cholesterol is 4.2 instead of a maximum of 4. Nice HDL though.

I'm 52, BMI of 22.5, carry most of my weight on my hips and bum, can run 10k in under 53 minutes. I exercise plenty - probably about 6 hours a week of proper sweat (running, gym, spin, tennis) and average 13k steps a day.

I just don't know whether I should be worried or just ignore. I could lose weight but probably not more than about 7kg without veering into gaunt territory. I could cut down on alcohol and I do have quite a lot of milky coffee so could swap to oat milk (urgh). But I don't know
a) how much difference that would make
b) whether I need to lower it.

There seems to be so much conflicting advice. Text from GP just said, it's raised and a link to not very informative NHS page.

Thanks

I don't think it's a big deal. My cardiac consultant said they look at cholesterol in the round in terms of cardiac risk- so if you have high cholesterol but are a healthy weight and do exercise, eat mostly healthy etc they aren't that bothered. Mine was 5.7 when I had that discussion with him and he said it didn't warrant any further action. He pointed to genetics having a factor which obviously you can't do anything about. Sounds like you are in the 'healthy in the round' camp

I look at lipid results. These are ok.
Good HDL. Good ratio (below 4.5 is good).
We ask specifically for the bad fats - triglycerides (diet and lifestyle related) and LDL (made in the liver, high can be hereditary). Your results don't seem to specify how your non HDL is made up of these.
6 is only the overall cholesterol figure, it's the ratio/the balance of good to bad that's important.
Hopefully your hba1c (sugar) has been checked as diabetes is a massive risk factor for stroke and heart attack in women, sixfold. And your BP too.
Unless your Q Risk (CVD risk over next ten years is over 10%, they should calculate this for you and would then start talking statins) or you have a particularly high incidence of stroke and heart in the family, I wouldn't worry too much.

Thank you so much for these replies, which confirms what I suspected/hoped - that in themselves they're not worth worrying about. My blood pressure is normal and my hba1c wasn't checked so I'll get that done next time.

I remember my mother having high cholesterol and giving up her daily boiled egg, wrongly but that was the advice of the time. So I think it might be genetic. She's now in her 80s with no heart issues, despite very very low levels of exercise or fitness.
