HDL Cholesterol, Explained in Plain Language

Quick Answer (TL;DR)

HDL helps carry cholesterol out of your arteries and back to the liver. Higher HDL is generally associated with lower risk.

What It Means

HDL stands for high-density lipoprotein. On a lipid panel it sits beside LDL and triglycerides. Roughly, above 1.0 mmol/L (40 mg/dL) for men and 1.3 mmol/L (50 mg/dL) for women is considered favourable.

Why It Matters for Your Health

HDL helps explain your overall pattern of risk. A good LDL number alongside very low HDL and high triglycerides still describes a metabolic problem worth addressing.

Recommended Biomarker or Metric to Track

Record HDL, LDL and triglycerides together each time, not just one line.

Questions to Ask Your Doctor

Targeted questions based on latest clinical consensus statements.

1What is my HDL, and how does it fit with my other lipids?
2Does my HDL change how we interpret my LDL?
3Which activities would help most in my case?
4Is my triglyceride to HDL ratio a concern?
5When should we recheck the full panel?
