What are the recommended lifestyle and pharmacologic strategies to raise high‑density lipoprotein (HDL) cholesterol to target levels (≥40 mg/dL in men, ≥50 mg/dL in women)?

Strategies to Raise HDL Cholesterol to Target Levels

Begin with intensive lifestyle modifications—weight loss, regular aerobic exercise (at least 30 minutes most days), smoking cessation, and dietary changes (reducing saturated fat to <7% of calories while increasing unsaturated fats to 15-20%)—which can collectively raise HDL-C by 10-13%; if HDL remains <40 mg/dL in men or <50 mg/dL in women despite lifestyle changes, add pharmacotherapy with niacin as first-line (most effective HDL-raising agent) or fibrates as an alternative, particularly in high-risk patients after LDL goals are achieved. 1, 2

Target HDL Levels

• Men: HDL ≥40 mg/dL 1
• Women: HDL ≥50 mg/dL 1
• Women naturally have HDL levels approximately 10 mg/dL higher than men, justifying the higher target 3

Lifestyle Interventions (First-Line Approach)

Dietary Modifications

• Reduce saturated fat to <7% of total calories 1
• Limit cholesterol intake to <200 mg/day 1
• Increase unsaturated fats to 15-20% of calories (particularly monounsaturated fats) 2
• Consider plant stanols/sterols (up to 2 g/day) and increased soluble fiber (10-25 g/day) 1

Physical Activity

• At least 30 minutes of moderate-intensity aerobic activity on most (preferably all) days of the week 1, 2
• Vigorous-intensity activity (≥60% maximum capacity) for 20-40 minutes on 3-5 days/week provides additional benefits 1
• Add resistance training: 8-10 different exercises, 1-2 sets per exercise, 10-15 repetitions at moderate intensity, 2 days/week 1

Weight Management

• Target 10% body weight reduction in the first year for overweight/obese patients 1
• Goal BMI: 18.5-24.9 kg/m² 1
• Weight loss combined with diet and exercise can increase HDL-C by 10-13% 2

Smoking Cessation

• Mandatory intervention—smoking cessation independently raises HDL-C 2

Alcohol Consumption

• Moderate alcohol intake may beneficially affect HDL-C, though this must be balanced against other health risks 2

Pharmacologic Interventions (When Lifestyle Modifications Are Insufficient)

Timing of Pharmacotherapy

• Initiate or intensify lifestyle changes first 1
• Evaluate lifestyle interventions at 6-week intervals, with consideration of pharmacotherapy between 3-6 months 1
• For high-risk patients (established CVD, diabetes, 10-year risk >20%), consider pharmacotherapy earlier after LDL goals are achieved 1

First-Line Pharmacologic Agent: Niacin (Nicotinic Acid)

• Most effective agent for raising HDL-C 1, 4, 5
• Use with caution in diabetic patients due to potential effects on glycemic control 1
• Extended-release formulations improve tolerability 4
• Recommended for high-risk women when HDL is low after LDL goal is reached (Class IIa recommendation) 1
• Consider for other at-risk patients with multiple risk factors and 10-year risk 10-20% (Class IIb recommendation) 1

Second-Line Pharmacologic Agent: Fibrates

• Fibrates (gemfibrozil, fenofibrate) significantly raise HDL-C without affecting glycemic control 1
• Particularly useful in diabetic patients where niacin is relatively contraindicated 1
• FDA-approved for raising HDL-C in primary hypercholesterolemia or mixed dyslipidemia 6
• Recommended for high-risk women when HDL is low after LDL goal is reached (Class IIa recommendation) 1

Statins (Adjunctive Role)

• Statins have variable and modest effects on HDL-C 1
• High-dose statins provide moderate HDL-raising effects 1
• Consider in patients who also need LDL lowering 1

Combination Therapy

• For combined hyperlipidemia: statin + fibrate or statin + niacin 1
• Warning: Combination of statins with fibrates or niacin carries increased risk of myositis—monitor carefully 1

Special Populations

Diabetic Patients

• Optimal glycemic control is the first priority—improved glucose control can favorably affect HDL levels 1
• Fibrates are preferred over niacin for HDL raising due to glycemic concerns 1
• Target HbA1c <7% 1

High-Risk Patients (Established CVD, 10-year risk >20%)

• More aggressive pharmacotherapy is warranted 1
• Consider niacin or fibrate therapy after LDL goal is reached (Class IIa recommendation) 1

Women

• Higher HDL target (≥50 mg/dL) is appropriate given naturally higher baseline levels 1, 3
• Low HDL poses disproportionate risk in women compared to men 3
• Total cholesterol-to-HDL ratio is more predictive of CAD in women than men 3

Monitoring Strategy

• Measure lipid panel annually in adults with risk factors 1, 7
• If values are at low-risk levels (HDL >50 mg/dL, LDL <100 mg/dL, triglycerides <150 mg/dL), reassess every 2 years 1, 7, 8
• More frequent monitoring for patients on lipid-lowering therapy 7

Common Pitfalls to Avoid

• Do not rely solely on statins to raise HDL—their effect is modest and variable 9
• Do not use niacin as first-line in diabetics without careful glycemic monitoring 1
• Do not combine statins with fibrates or niacin without monitoring for myositis 1
• Do not neglect lifestyle interventions—they are foundational and can achieve 10-13% HDL increase when combined 2
• Do not forget that raising HDL is a secondary priority after achieving LDL goals 1
