Question 1

What does a high LDL cholesterol level mean?

Accepted Answer

High LDL means more cholesterol is circulating in your blood than your body can use, and the excess gets deposited in your artery walls. Over years this forms plaques that narrow arteries and raises your risk of heart attack and stroke. Most adults should aim for LDL under 3.0 mmol/L; people with existing heart disease or diabetes should target lower.

Question 2

Do I need to fast before an LDL test?

Accepted Answer

Traditionally yes, 9–12 hours — but recent European Society of Cardiology guidance accepts non-fasting LDL for routine screening. If your doctor has ordered a full lipid panel including triglycerides, fasting still gives the most accurate picture. At Ahead we recommend fasting for your first test.

Question 3

Can lifestyle changes lower my LDL cholesterol?

Accepted Answer

Yes — often substantially. Cutting saturated fat (butter, processed meats, palm oil), eating more fibre (oats, legumes, vegetables), losing excess weight, and getting 150+ minutes of weekly exercise can drop LDL by 10–25%. If lifestyle alone doesn't reach your target, statins remain the best-studied medical option.

Question 4

What's the difference between LDL, HDL, and total cholesterol?

Accepted Answer

Total cholesterol is the sum of LDL, HDL, and a fraction of your triglycerides. LDL is the "bad" carrier that delivers cholesterol to tissues — high levels damage arteries. HDL is the "good" carrier that removes cholesterol back to the liver — higher is generally better. Looking at LDL and HDL separately gives a much better picture than total cholesterol alone.

Question 5

How often should I check my LDL?

Accepted Answer

For adults with normal levels and no risk factors, every 4–6 years is usually enough. If you have diabetes, high blood pressure, a family history of heart disease, or are on cholesterol medication, your doctor will want to recheck more often — typically every 6–12 months.
