i have been told today that i have to go for a check up at my doctors as a full blood test i had done a week ago has come back with my cholesterol is high and is at 5.3, which i believe is fairly high especially for a female and i am 35 yrs old. a year ago was the last time i had a full blood test done and everything was ok but i was 2 stone heavier than i am now, i would say that i am over weight but not obese, hence the diet! i exercise regularly and have been on a long term diet and i am just bewildered how i can get high cholesterol now. could someone tell me actually how high 5.3 is and how damaging this score can be and any ideas why it could be this high from the info i have given cos i am totally bemused by it all. thank you very much, any information would be a great help to me.
