My cholesterol is 265, HDL 171, LDL 86. Can HDL get too high?

HIGH HDL=Good! If you Hdl is high, that is good, and can decrease your overall risk for heart disease. our LDL as noted is stable at 86, but now there is new data to suggest you should get a risk calculation based on some other factors. See your dr. for a good eval and discussion as to whether you need any medications, etc.
