A standard lipid panel returns four numbers: total cholesterol, LDL ("bad") cholesterol, HDL ("good") cholesterol, and triglycerides. Many patients receive these results without a clear explanation of what they mean or what action to take. This guide demystifies your cholesterol panel so you can have a more informed conversation with your physician about your cardiovascular health.
Understanding the Four Lipid Values
LDL cholesterol (low-density lipoprotein) is the primary target of cholesterol treatment. LDL particles deposit cholesterol in arterial walls, contributing to plaque buildup and atherosclerosis. For most healthy adults without heart disease, LDL below 100 mg/dL is ideal; for high-risk patients with existing cardiovascular disease or diabetes, many guidelines recommend below 70 mg/dL.
HDL cholesterol (high-density lipoprotein) is protective — it transports cholesterol from arterial walls back to the liver for removal. Higher is better. An HDL below 40 mg/dL in men and below 50 mg/dL in women is associated with increased cardiovascular risk. Exercise is the most effective lifestyle intervention to raise HDL.
Triglycerides are another fat type in the blood. Normal is below 150 mg/dL; borderline high is 150–199 mg/dL; levels above 500 mg/dL pose a risk for pancreatitis. High triglycerides are strongly associated with refined carbohydrate and alcohol intake, obesity, and insulin resistance.
When Is Treatment Recommended?
- High LDL in a patient with established heart disease: statins strongly recommended
- High LDL plus multiple risk factors (diabetes, hypertension, smoking, age): statin benefit high
- Isolated high LDL in a young, low-risk adult: lifestyle modification first
- Very high triglycerides (above 500): triglyceride-lowering medications (fibrates, omega-3s)
- Low HDL: lifestyle changes (exercise, smoking cessation, weight loss) most effective
