HDL Cholesterol - The "Good" Cholesterol
Understanding HDL cholesterol, why it matters, and how to improve your levels.
HDL Cholesterol - The "Good" Cholesterol
What is HDL?
High-Density Lipoprotein (HDL) cholesterol is often called "good" cholesterol because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL cholesterol are associated with a lower risk of heart disease.
Why It Matters
HDL acts like a cleanup crew in your bloodstream:
- Removes excess cholesterol: Picks up cholesterol from arteries and tissues
- Transports to liver: Carries it to your liver for disposal
- Protects arteries: Helps prevent plaque buildup in arterial walls
- Anti-inflammatory: Has protective effects beyond just cholesterol transport
Optimal Ranges
- Men: 40 mg/dL or higher (optimal: 60+ mg/dL)
- Women: 50 mg/dL or higher (optimal: 60+ mg/dL)
- Risk reduction: Every 1 mg/dL increase in HDL reduces heart disease risk by 2-3%
How to Improve HDL
Lifestyle Changes
- Exercise regularly: 30 minutes of moderate activity most days
- Quit smoking: Smoking lowers HDL by 10-15%
- Lose weight: Every 6 pounds lost can raise HDL by 1 mg/dL
- Choose healthy fats: Olive oil, avocados, nuts
- Limit refined carbs: Reduce sugar and processed foods
- Moderate alcohol: May raise HDL but has other risks (consult doctor)
Foods That Help
- Fatty fish (salmon, mackerel, sardines)
- Nuts and seeds (almonds, walnuts, chia seeds)
- Olive oil and avocados
- Whole grains
- Purple and red fruits (berries, grapes)
When to Be Concerned
- Low HDL (<40 mg/dL men, <50 mg/dL women): Increased cardiovascular risk
- Very high HDL (>100 mg/dL): Rarely, can indicate genetic conditions
- Ratio matters: Total cholesterol to HDL ratio should be below 5:1
AI Analysis Tips
When analyzing lab reports, our AI considers:
- HDL in context with total cholesterol and LDL
- Trends over time, not just single values
- Individual risk factors and family history
- Lifestyle factors that may affect results
