Total Cholesterol
Total cholesterol measures the sum of LDL, HDL, and VLDL cholesterol circulating in blood. It is a baseline cardiovascular risk indicator, though LDL, HDL, and ApoB give more precise risk assessment. Values above 200 mg/dL warrant closer analysis of the full lipid panel. Levels reflect diet, genetics, liver function, and hormonal status.
Units: mg/dL; some labs report mmol/L (mmol/L = mg/dL × 0.0259). Check the units on your report before comparing to any range here.

What is Total Cholesterol?
Total Cholesterol measures the sum of all cholesterol in your blood, including LDL (low-density lipoprotein), HDL (high-density lipoprotein), and VLDL (very low-density lipoprotein). Cholesterol is a waxy, fat-like substance essential for building cell membranes, producing hormones (testosterone, estrogen, cortisol), synthesizing vitamin D, and creating bile acids for digestion.
While total cholesterol provides a snapshot of lipid status, it is less informative than its components because it combines both "good" HDL and "bad" LDL cholesterol. A person with total cholesterol of 220 mg/dL could have high HDL (protective) or high LDL (harmful)—vastly different cardiovascular risk profiles. This is why modern guidelines emphasize LDL, HDL, and non-HDL cholesterol (total minus HDL) over total cholesterol alone.
Total cholesterol was historically used for cardiovascular risk assessment, with <200 mg/dL considered desirable. However, this arbitrary threshold has been challenged—25% of heart attacks occur in people with "normal" total cholesterol. Advanced lipid testing (ApoB, LDL particle number, Lp(a)) provides superior risk stratification. Total cholesterol remains useful as an initial screening tool and for calculating non-HDL cholesterol (total - HDL), which correlates well with ApoB.
Why Total Cholesterol Is A Starting Point, Not the Answer
- Initial screening: Widely available, inexpensive test for identifying lipid abnormalities requiring further evaluation
- Non-HDL calculation: Total cholesterol minus HDL equals non-HDL cholesterol, which captures all atherogenic particles (LDL + VLDL + remnants) and correlates well with cardiovascular risk
- Historical tracking: Decades of epidemiological data link elevated total cholesterol to heart disease risk, though other markers are now preferred
- Familial hypercholesterolemia detection: Very high total cholesterol (>300 mg/dL) in young adults suggests genetic disorder requiring aggressive treatment
- Limited utility alone: Cannot distinguish protective HDL from harmful LDL. Must be interpreted with HDL, LDL, triglycerides
- Medication monitoring: Tracks overall lipid-lowering effect of statins and other therapies

Desirable<200 mg/dL▼
- Associated with lower cardiovascular risk in population studies
- However, risk depends on HDL and LDL components
- Total cholesterol 180 mg/dL with HDL 80 (excellent) differs dramatically from 180 mg/dL with HDL 30 (poor)
- Always evaluate with lipid panel components
Borderline High200-239 mg/dL▼
- Moderate cardiovascular risk
- Check complete lipid panel with LDL, HDL, triglycerides
- Calculate non-HDL cholesterol (total - HDL); target <130 mg/dL
- Consider lifestyle modifications (diet, exercise, weight loss)
- If LDL >130 or multiple risk factors, consider statin therapy
High240-300 mg/dL▼
- Elevated cardiovascular risk
- Requires comprehensive lipid panel, cardiovascular risk assessment (Framingham, ASCVD calculator), and likely pharmacotherapy
- If LDL >160 mg/dL, statin therapy indicated
- Screen for familial hypercholesterolemia, especially if family history of early heart disease
- Aggressive lifestyle modification essential
Very High (Possible Familial Hypercholesterolemia)>300 mg/dL▼
- Very high cardiovascular risk
- Strongly suggests familial hypercholesterolemia (FH), especially if present in young adults (<40 years) or with family history
- FH affects 1 in 250 people and increases heart attack risk 20-fold
- Requires high-intensity statin (atorvastatin 40-80 mg or rosuvastatin 20-40 mg), possibly combined with ezetimibe or PCSK9 inhibitors
- Early intervention critical—untreated FH causes heart disease by age 50-60 in men, 60-70 in women

What raises or lowers Total Cholesterol
Causes of high Total Cholesterol
High total cholesterol causes:
- Diet: High saturated fat, trans fats, excess calories
- Obesity: Especially abdominal obesity
- Sedentary lifestyle: Lack of exercise worsens lipid profile
- Genetics: Familial hypercholesterolemia (FH), familial combined hyperlipidemia
- Secondary causes: Hypothyroidism (check TSH), diabetes, kidney disease, liver disease
- Medications: Thiazide diuretics, beta-blockers, corticosteroids, anabolic steroids, cyclosporine
- Age and gender: Cholesterol rises with age. Women have lower cholesterol premenopause, increases after menopause
Causes of low Total Cholesterol
Low total cholesterol (<160 mg/dL) causes:
- Malnutrition or malabsorption
- Hyperthyroidism (increased metabolism)
- Liver disease (reduced cholesterol synthesis)
- Severe illness or sepsis
- Certain medications (statins - iatrogenic)
- Genetic lipid disorders (very rare)
- Generally not harmful unless very low (<120 mg/dL) which may indicate serious illness
Symptoms when Total Cholesterol is high or low
When high
Very high cholesterol (>300 mg/dL) physical signs:
- Xanthomas: Cholesterol deposits in tendons (Achilles, hands)
- Xanthelasma: Yellow plaques on eyelids
- Corneal arcus: White/gray ring around iris (if <45 years old)
- Family history: Early heart disease in relatives
Physical signs are more common with familial hypercholesterolemia. Most people with high cholesterol have no visible signs—screening is essential.
When low
High cholesterol itself causes no symptoms. Symptoms only appear from complications:
- Chest pain (angina): If coronary artery disease from chronic high cholesterol
- Xanthomas: Yellowish cholesterol deposits in skin/tendons (elbows, knees, Achilles) if very high cholesterol >300 mg/dL or familial hypercholesterolemia
- Xanthelasma: Cholesterol deposits around eyelids
- Corneal arcus: Gray-white ring around cornea in people <45 suggests familial hypercholesterolemia
- Stroke or heart attack: First "symptom" of high cholesterol is often a cardiovascular event
High cholesterol is a "silent killer"—no symptoms until atherosclerosis causes heart attack, stroke, or peripheral artery disease. This is why screening and early treatment are critical.
How to move Total Cholesterol
Effect sizes (how much something moves the marker) appear only where the paper cited under the item states them. Talk to your clinician before starting or changing any medication or supplement.
Dietary Modifications
- Reduce saturated fat: Limit to <7% of calories. Major sources: red meat, butter, cheese, coconut oil. Replacing saturated fat with unsaturated fat lowers LDL
- Eliminate trans fats: Avoid partially hydrogenated oils, fried foods, commercial baked goods. Trans fats raise LDL and lower HDL
- Increase soluble fiber: 5-10g daily (oats, barley, psyllium, beans, apples). Soluble fiber lowers LDL modestly
- Plant sterols/stanols: In a meta-analysis of randomised trials, 0.6-3.3 g daily lowered LDL cholesterol by 6-12% on average (Ras 2014)
- Mediterranean diet: Emphasize olive oil, fish, nuts, vegetables, whole grains. Lowers LDL and reduced cardiovascular events in trials
Lifestyle Interventions
- Aerobic exercise: 150+ minutes/week moderate intensity. Raises HDL and modestly lowers LDL
- Weight loss: Losing excess weight lowers total cholesterol and improves the HDL/LDL ratio
- Smoking cessation: Quitting raises HDL within weeks
- Limit alcohol: Moderate intake (1-2 drinks daily) may raise HDL but also increases triglycerides. Avoid if triglycerides elevated
- Stress reduction: Chronic stress elevates cortisol, which increases cholesterol synthesis. Meditation, yoga, adequate sleep help
Statin Therapy (if LDL Elevated)
- Primary prevention: Statin if LDL >190 mg/dL, diabetes age 40-75, or 10-year ASCVD risk ≥7.5%. Reduces cardiovascular events
- Moderate-intensity: Atorvastatin 10-20 mg or rosuvastatin 5-10 mg. Lowers LDL substantially
- High-intensity: Atorvastatin 40-80 mg or rosuvastatin 20-40 mg. The 2018 AHA/ACC cholesterol guideline uses these to lower LDL-C by 50% or more (Grundy 2018)
- Secondary prevention: If established heart disease, stroke, or peripheral artery disease, high-intensity statin regardless of cholesterol level
- Monitor: Check lipid panel 4-12 weeks after starting, then every 3-12 months. Check ALT, CK if symptoms. Consider CoQ10 100-200 mg daily for muscle symptoms
Additional Lipid-Lowering Medications
- Ezetimibe: 10 mg daily blocks cholesterol absorption. Lowers LDL further on top of a statin. Add if LDL not at goal with statin
- PCSK9 inhibitors: Evolocumab or alirocumab injection every 2-4 weeks. In the FOURIER trial, evolocumab added to a statin lowered LDL cholesterol by 59% (Sabatine 2017). For familial hypercholesterolemia or statin-intolerant patients
- Bempedoic acid: 180 mg daily. Lowers LDL moderately. Alternative for statin-intolerant patients
- Bile acid sequestrants: Cholestyramine, colesevelam. Lower LDL moderately but GI side effects are common
- Niacin: No longer recommended—doesn't reduce cardiovascular events despite raising HDL
Source: Evolocumab and Clinical Outcomes in Patients with Cardiovascular Disease.
Advanced Lipid Testing and Monitoring
- Non-HDL cholesterol: Calculate as Total - HDL. Captures all atherogenic particles
- ApoB testing: More accurate than LDL for cardiovascular risk. Each LDL particle has one ApoB. The ApoB page lists who sets which target
- LDL particle number: If LDL-C normal but triglycerides >150, check LDL-P. May have small dense LDL with high particle count despite "normal" LDL-C
- Lp(a): Check once—genetically determined. Lp(a) above 50 mg/dL is a guideline risk-enhancing factor. Requires aggressive LDL lowering
- CAC score: Coronary artery calcium at age 40-75 if uncertain about statin initiation. CAC >100 indicates high risk requiring statin
When to retest
- Initial screening: Adults age 20-39 check every 5 years. Age 40+ check every 1-2 years
- After lifestyle changes: Retest lipid panel in 6-12 weeks following diet, exercise, weight loss. Expect a reduction
- After starting statin: Check lipid panel 4-12 weeks after initiation or dose change. Adjust to achieve LDL goals
- If on stable therapy: Check annually for adherence and monitoring. More frequently if not at goal
- After cardiovascular event: Check lipid panel 24-48 hours after heart attack, then 4-6 weeks later. Cholesterol drops acutely during illness
- Familial hypercholesterolemia: Screen children at age 2 if parent has FH. Otherwise screen all children age 9-11 and 17-21
Scientific Evidence
Cholesterol and Cardiovascular Death
A meta-analysis of 14 cohort reports (1,055,309 people) found higher total cholesterol associated with cardiovascular death (pooled HR 1.27), as was LDL cholesterol (HR 1.21), while higher HDL cholesterol was associated with lower risk (HR 0.60).
Statin Benefit Trials
Across 26 statin trials (about 170,000 participants), each 1.0 mmol/L (about 39 mg/dL) reduction in LDL cholesterol cut major vascular events by about a fifth (RR 0.78) and all-cause mortality by 10%, including in people starting below 2 mmol/L. No threshold was found.
Non-HDL Cholesterol
In 38,153 statin-treated patients from 8 trials, on-treatment non-HDL cholesterol was more strongly associated with future cardiovascular events (HR 1.16 per standard deviation) than LDL cholesterol (1.13) or apoB (1.14).
