My cholesterol is high. Do I need a statin?
It depends on your overall risk, not on the number. A ten-year cardiovascular risk score is what decides it.
Someone with moderately raised cholesterol and no other risk factors may need nothing. Someone with the same result who smokes and has high blood pressure may benefit substantially.
Do I need to fast before the test?
Usually no. Non-fasting samples are acceptable for routine lipid testing.
A fasting repeat is worth doing if triglycerides come back markedly raised, since those are most affected by recent eating.
Are statins safe?
They are among the best-studied medicines in use, and serious side effects are rare.
Muscle aches are the common complaint — and in blinded trials, most people who report them on a statin report them on placebo too. That does not mean the ache is imagined; it means the statin is often not the cause.
Where symptoms are genuine, switching statin or lowering the dose usually resolves them. Stopping without saying anything is the outcome worth avoiding.
I eat well and exercise. Why is mine high?
Cholesterol is substantially genetic. Diet influences it, but it does not determine it.
Very high levels in someone with a good diet raise the question of familial hypercholesterolaemia, which affects around 1 in 250 people and is badly underdiagnosed.
Could something else be raising it?
An underactive thyroid, which is common and easily checked. Treating it can normalise cholesterol without any lipid medication at all.
Also poorly controlled diabetes, kidney disease, and some medications.
What is non-HDL cholesterol?
Total cholesterol minus HDL — so it captures all the harmful fractions in one figure.
UK practice now favours it over LDL because it does not require fasting and reflects risk slightly better.
Is high HDL protective?
Higher HDL is associated with lower risk, but raising it with medication has not been shown to help.
Treat the LDL and non-HDL — that is where the benefit lies.
Should my children be tested?
If familial hypercholesterolaemia is suspected or confirmed in you, yes. It is inherited, and identifying it early changes outcomes considerably.
NHS genetic and lipid clinics do this free, and testing relatives is a routine part of the pathway.
