Cholesterol panels: LDL, HDL, and triglycerides in plain language
A standard lipid panel reports several numbers that don't all mean the same thing for your risk.
LDL cholesterol is often shorthand for "bad cholesterol" because it's the primary particle that deposits into artery walls, contributing to the plaque buildup underlying atherosclerosis — lower is generally better, and target ranges get more aggressive for anyone with existing cardiovascular risk factors.
HDL is the counterpart, sometimes called "good cholesterol," believed to help transport cholesterol away from arteries back to the liver for processing — higher levels are generally favorable, though recent research has tempered some of the earlier enthusiasm about directly raising HDL as a treatment target.
Triglycerides are a different lipid entirely — a measure of fat circulating in the blood, more directly tied to diet, alcohol intake, and blood sugar control than LDL or HDL, and elevated levels are an independent cardiovascular risk factor worth managing on its own terms.
Total cholesterol, the sum figure often reported first, is the least individually informative of the numbers — two people with an identical total cholesterol can have very different actual risk profiles depending on how that total splits between LDL, HDL, and triglycerides.
