Your doctor hands you a lab report with numbers like “LDL: 142 mg/dL” and “HDL: 48 mg/dL.” What does it all mean, and should you be worried? Here’s a clear, jargon-free breakdown of everything you need to know about cholesterol.
What Is Cholesterol, Really?
Cholesterol is a waxy, fat-like substance your body actually needs — it’s used to build cell membranes, produce hormones, and make vitamin D. The problem isn’t cholesterol itself; it’s when certain types accumulate in your arteries and form plaques that restrict blood flow.
Cholesterol travels through your bloodstream in packages called lipoproteins. The two main types are LDL and HDL.
LDL: The “Bad” Cholesterol
LDL (low-density lipoprotein) carries cholesterol from the liver to cells throughout the body. When there’s too much LDL, it can deposit in artery walls, forming plaques that narrow arteries and increase the risk of heart attack and stroke.
LDL targets:
- Less than 100 mg/dL — Optimal
- 100–129 mg/dL — Near optimal
- 130–159 mg/dL — Borderline high
- 160–189 mg/dL — High
- 190 mg/dL and above — Very high
If you have diabetes, heart disease, or other risk factors, your doctor may recommend keeping LDL below 70 mg/dL.
HDL: The “Good” Cholesterol
HDL (high-density lipoprotein) acts like a cleanup crew — it picks up excess cholesterol from arteries and carries it back to the liver for disposal. Higher HDL is generally better.
HDL targets:
- 60 mg/dL and above — Protective (reduces heart disease risk)
- 40–59 mg/dL — Acceptable
- Less than 40 mg/dL (men) / 50 mg/dL (women) — Low (increases risk)
Triglycerides: The Often-Overlooked Number
Triglycerides are a type of fat in your blood. High triglycerides are often linked to excess sugar and refined carbohydrate intake, obesity, and physical inactivity.
Triglyceride targets:
- Less than 150 mg/dL — Normal
- 150–199 mg/dL — Borderline high
- 200–499 mg/dL — High
- 500 mg/dL and above — Very high (pancreatitis risk)
Total Cholesterol: The Big Picture
Total cholesterol is the sum of LDL + HDL + 20% of triglycerides. While it’s a useful screening number, it doesn’t tell the whole story — someone with high HDL might have a high total cholesterol but actually be at low risk.
Total cholesterol targets: Less than 200 mg/dL is desirable; 200–239 mg/dL is borderline high; 240 mg/dL and above is high.
How to Improve Your Numbers Naturally
To lower LDL: Reduce saturated fats (red meat, full-fat dairy), eliminate trans fats, increase soluble fiber (oats, beans, apples), and add plant sterols.
To raise HDL: Exercise regularly (aerobic activity is most effective), quit smoking, lose excess weight, and consume healthy fats (olive oil, avocados, nuts).
To lower triglycerides: Cut sugar and refined carbs, limit alcohol, increase omega-3 fatty acids (fatty fish, flaxseed), and exercise.
When Medication Is Needed
Lifestyle changes are the first line of defense, but some people need medication (statins or other cholesterol-lowering drugs) due to genetics, existing heart disease, or insufficient response to lifestyle changes. This is a conversation to have with your doctor based on your complete cardiovascular risk profile — not just your cholesterol numbers alone.
When did you last have your cholesterol checked? Do you know your LDL and HDL numbers?
