What this marker measures
LDL is the primary target of lipid-lowering therapies. Reducing LDL through diet, exercise, or medication (statins) is one of the most well-established strategies for lowering cardiovascular risk.
High or low: what it can mean
High LDL
Elevated LDL is associated with a gradually increased risk of cardiovascular disease over decades. The target level depends on an individual's overall risk profile, which doctors assess using multiple factors.

Low LDL
Very low LDL is generally not a concern on its own and may result from statin therapy, a very low-fat diet, or genetic factors.

Lifestyle considerations
- •Saturated and trans fats raise LDL; replacing them with unsaturated fats (olive oil, nuts) can help
- •Soluble fibre from oats and legumes helps reduce LDL absorption
Frequently asked questions
What is LDL?
+
LDL ("bad" cholesterol) carries cholesterol to tissues throughout the body. When LDL is too high, cholesterol can build up in artery walls, gradually narrowing them over time.
What does LDL measure?

What supports healthy LDL levels?
+
Saturated and trans fats raise LDL; replacing them with unsaturated fats (olive oil, nuts) can help. Soluble fibre from oats and legumes helps reduce LDL absorption
