Cholesterol has nothing to do with lupus. If you have developed high numbers and have a sensible diet then it is genetic. My wife has high numbers and eats better than I do but my numbers are low. However, my good cholesterol is low despite a life of working out. That is just genetics and there is not much that can be done.
Lupus impacts many things but I don't think it has ever been connected to lupus. One thing to watch out when taking statin drugs like Zocor is for muscle weakness. Statins can cause statin induced myositis or even trigger myositis. It is rare but don't ignore any symptoms. If you get them talk to your doctor. If it is statin induced myositis it will go away after stopping the drug.
