First-line treatments
Aerobic Exercise Program
Regular moderate-intensity aerobic exercise such as walking, cycling, or swimming has been shown to raise HDL levels by 5-10%. Exercise recommendations include at least 150 minutes weekly of moderate activity or 75 minutes of vigorous activity.
Antimicrobial or antiviral therapy
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Heart-Healthy Diet
Mediterranean-style dietary patterns emphasizing olive oil, fatty fish, nuts, and whole grains support favorable lipid profiles. This approach includes reducing saturated fats and increasing monounsaturated fatty acids and omega-3 intake.
Additional treatment options
Smoking Cessation
Complete cessation of tobacco use, including vaping, removes a significant factor that suppresses HDL function. Smoking cessation also improves overall cardiovascular function and reduces oxidative stress.
lifestyleLipid Profile Monitoring
Regular lipid panel testing every 1-5 years depending on risk factors tracks HDL trends and overall cardiovascular risk. This allows timely intervention if significant changes occur.
monitoringNiacin Supplementation
Niacin (vitamin B3) supplementation may provide modest HDL elevation in some individuals when lifestyle measures are insufficient. It should only be used under medical supervision due to potential side effects.
