Total cholesterol, LDL, HDL, triglycerides — what they mean and which ones actually matter.
A cholesterol panel reports several numbers, and the jargon can be confusing. Understanding them is worth the effort — these numbers are among the strongest predictors of cardiovascular risk.
LDL ('bad' cholesterol) contributes to plaque buildup in arteries; lower is better. HDL ('good' cholesterol) helps clear cholesterol from the bloodstream; higher is better. Triglycerides reflect blood fats tied to diet and metabolism; lower is better. Total cholesterol is the sum, but the breakdown matters more than the total.
Optimal targets vary by individual risk. For most adults, an LDL under 100 is desirable; for those with diabetes or existing heart disease, the target is even lower. Your provider will interpret your results in context.
Improvement usually starts with lifestyle: reducing saturated and trans fats, increasing soluble fiber (oats, beans, fruit), regular movement, and weight management. When lifestyle isn't enough, statin medications are safe and effective for most people.
