My cholesterol is higher than that - it was 7.4 when measured a few weeks ago. Even so the doc was not worried because I am not overweight (although just under 9 stone - but medium frame size), exercise a lot, have a very healthy diet masses of fruit and veg, lean protein, yogurt, eggs, nuts etc but eat very few carbs and almost no sugar except fruit ( and wine/G & T at weekend

). There isn't anything else I can do. Doc said that some people have naturally higher cholesterol. She also did that Q test thing and I was low risk.
I certainly don't need any more oestrogen - OK my levels will be nothing like yours nearly50 - (that is very high - it is within the range of the ovulatory peak or late follicular phase and I presume you are still peri-menopausal so that will be some of your own - that would be probably too high to sustain into your 60's I imagine - due to having to take all that progestogen) - but I have no flushes and mine are probably consistent with early follicular phase. I haven't had them measured for years. I certainly would not increase oestrogen just to see if cholesterol is reduced.
I haven't read the links but wonder if my high protein/fruit/veg diet has something to do with it as I rarely eat bread, cereals, rice, pasta or potatoes - not even once a day.
nearly50 when I had mine done a year ago my HDL was 1.7, LDL 4.2, Total 6.5 but the ratio was 3.82 and it is OK if less than 4. Therefore I am puzzled about all of this (ie the individual readings) - my doc said the ratio was more important! I will have a look at the links at some point which probably explain...
