Start with the whole report
Cholesterol is needed by the body, but an excess of cholesterol in certain particles can contribute to artery disease. Total cholesterol combines different components. LDL and non-HDL help inform risk assessment; HDL is part of the picture, but a high HDL result does not cancel a high LDL result.
Why two people can have different targets
Your target depends on factors such as previous cardiovascular disease, diabetes and overall risk. Very high results or heart disease at young ages in close relatives may prompt assessment for inherited high cholesterol. High cholesterol usually causes no symptoms.
A MANAGEABLE NEXT STEP
What you can do today.
- Bring the complete laboratory report, including units, to your appointment. Compare results using the same units.
- Try replacing some saturated-fat-rich foods with options containing unsaturated fats, such as olive or rapeseed oil, nuts or seeds. Include fibre-rich foods such as oats, pulses and whole grains.
- Choose enjoyable activity and seek support to stop smoking if relevant. Keep prescribed treatment until you have discussed changes with your clinician.
What to discuss with your doctor.
- Which number is most relevant to me, and what is my target?
- Does my family history suggest inherited high cholesterol?
- Do I need treatment or another test, and when should we review it?
When to seek help.
A cholesterol result cannot explain away new symptoms. Chest pain, severe breathlessness or sudden weakness needs urgent assessment, regardless of what a blood test showed.
