What should you know about cholesterol levels by age?

A lipid profile usually includes total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides. The meaning of each result changes with the person’s wider picture. A younger adult may need assessment for inherited cholesterol problems or other causes, while an older adult’s result is considered with blood pressure, diabetes, smoking, kidney health and previous vascular disease. The same number can therefore lead to different advice for different people.

A single test is a snapshot. Recent illness, fasting instructions, medicines and changes in diet can affect interpretation. Your clinician may compare results over time and use a risk assessment to decide whether lifestyle measures, monitoring or treatment are appropriate.

Keep a record of the full report rather than total cholesterol alone. Ask which result needs attention and whether the sample should be repeated. Regular movement, more fibre-rich foods, less saturated fat, not smoking and a weight plan suited to you can support healthier levels. Do not stop prescribed medicine because a result looks improved; discuss any change first. A [Cholesterol Test](/treatments/diagnostics-and-screening/cholesterol-test/) explains how testing is performed, while [Statin Therapy](/treatments/medical-management/statin-therapy/) covers one possible treatment approach.

Arrange a routine appointment if a report is outside the range given by the laboratory, if close relatives had early heart or blood-vessel disease, or if you have stopped taking treatment. Seek urgent help for chest pressure, sudden breathlessness, fainting, or sudden weakness or difficulty speaking; these symptoms need assessment regardless of a cholesterol result.

Which part of my lipid profile matters most? How does my age change the risk assessment? Should I repeat the test, and do I need to fast? Could another condition or medicine be affecting the result? What improvement should we look for at the next review?
