title: After I had a heart attack and two bypass operations, I was put on Lipitor to lower my cholesterol. My cholesterol was never high--about 170-180 mg/dL. But my HDL was always low and triglycerides were somewhat high. Now my total cholesterol is 124 and my HDL has gone up slightly. My triglycerides are way down. My LDL cholesterol has fallen from 110 to 68. Is there any downside to such a low cholesterol level, other than the need to check my liver function tests?
