Since last two years I have HDL Cholesterol in the range of 90.My total cholesterol is 170, LDL 80, Triglycerides 80 .I am on Rosuvas 5mg,Clopilet 75 mg, Eltroxin 125mcg, Urimax0.4mg.My TSH /PSA/ liver/renal blood reports are OK. My FBS is 109/PPBS 108.My TMT/2DEco are OK. My CT Angio done 2010 shows 20/30% blockage. What is the reason for this high HDL. How to make this normal. How does this harm me? What other tests to do for knowing the reason for this high HDL
