Quick Answer (TL;DR)
LDL carries cholesterol into your artery walls. Lower LDL generally means lower cardiovascular risk.
What It Means
LDL stands for low-density lipoprotein. It is one line on a lipid panel, alongside HDL, triglycerides and total cholesterol. Targets are personal: they depend on your overall risk, not one number alone.
Why It Matters for Your Health
LDL that stays high over years contributes to plaque buildup in arteries, which raises the risk of heart attack and stroke.
Recommended Biomarker or Metric to Track
Keep each lipid panel result so you can see the trend rather than one snapshot.

Targeted questions based on latest clinical consensus statements.
1What is my LDL, and what target makes sense for me?
2What is my overall cardiovascular risk score?
3Would diet and exercise realistically be enough in my case?
4Is there a family history I should be screened for?
5When should we retest?
