I have elevated cholesterol, and for many years when I had blood work I was told to fast for 12 hours. Recently my primary care physician said that a non-fasting measurement would be as accurate. I have diabetes, and episodes of low blood sugar and fasting can sometimes cause a symptomatic drop in my blood sugar. What do you think? Ive read online that there is little evidence to support the use of statins in the primary prevention of cardiovascular disease and that the risks outweigh the benefits. I have no previous cardiovascular disease. How do I know if I should take statins?
