Lipoproteins and arterial plaque
Cholesterol is needed for hormones, vitamin D, and digestion-related substances, and the body makes what it needs. Lipoproteins transport fats in blood. LDL mainly carries cholesterol; VLDL carries triglycerides. HDL carries cholesterol from tissues back to the liver for removal. Excess cholesterol can combine with other substances to form arterial plaque, narrowing or blocking vessels. Transport roles help explain why lipid testing reports several values.
Silent elevation and vascular consequences
High cholesterol usually has no signs or symptoms. Its significance is related to plaque accumulation rather than a reliable warning sensation. Coronary, carotid, and peripheral arteries can be affected, increasing risk of coronary disease or stroke. Lack of symptoms does not establish a healthy cholesterol level. Testing and risk assessment matter because vascular changes can develop while a person feels well and notices no distinctive physical change.
