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

  1. Exercise regularly: 30 minutes of moderate activity most days
  2. Quit smoking: Smoking lowers HDL by 10-15%
  3. Lose weight: Every 6 pounds lost can raise HDL by 1 mg/dL
  4. Choose healthy fats: Olive oil, avocados, nuts
  5. Limit refined carbs: Reduce sugar and processed foods
  6. 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
