title: Ask the doctor. I'm 80, and I exercise or bike for an hour and a half almost every day and eat a healthy diet. I recently had a blood lipid assessment, and my HDL was 70 and my LDL was 42, But my internist wrote me saying that my LDL was too low and that I should cut my dose of atorvastatin from 40 mg to 20 mg a day. I also take 2,000 mg of niacin daily. Is there general agreement that one's LDL should not go below a certain point? Is mine too low?
