Silent Signs of High Cholesterol You Should Not Ignore
High cholesterol is described as silent because, for most people, it produces no sensation at all. It is discovered on a blood test, or it is discovered after a heart attack. That is why the physical clues that do exist are worth recognising.
The few visible signs
Cholesterol can deposit in tissues outside blood vessels, and when it does, the signs are quite specific:
- Xanthelasma: soft yellowish patches on the eyelids, usually near the inner corner
- Tendon xanthomas: firm lumps over the knuckles, elbows or the Achilles tendon at the back of the ankle
- Arcus senilis: a pale grey-white ring around the edge of the cornea, which is meaningful mainly when it appears before about age 45
- Eruptive xanthomas: small yellow bumps on the buttocks, elbows or knees, associated with very high triglycerides
These signs point towards a genetic lipid disorder, most often familial hypercholesterolaemia, rather than ordinary diet-related elevation. They justify testing the whole immediate family.
Symptoms that come from the consequences
Cholesterol itself does not hurt, but the narrowing it causes eventually does:
- Chest tightness or pressure on exertion that eases with rest
- Calf pain when walking a set distance that reliably stops when you stand still, a pattern called claudication
- Breathlessness disproportionate to the effort
- Erectile dysfunction, which often precedes cardiac symptoms because penile arteries are smaller
Any of these deserves assessment, not reassurance.
Who should be tested even with no signs
Testing is reasonable in adults from their twenties onwards, and it is important if you have:
- A parent or sibling with heart disease before age 55 in men or 65 in women
- Diabetes or prediabetes
- High blood pressure
- Central obesity or a raised waist measurement
- Chronic kidney disease
- An inflammatory condition such as rheumatoid arthritis
- A history of smoking
- Polycystic ovary syndrome or a history of pre-eclampsia

South Asian populations develop atherosclerotic disease earlier and at lower body weights than many other groups, so a normal-looking build is not a reason to skip the test.
Reading the lipid panel
A standard panel reports total cholesterol, LDL, HDL, triglycerides and often non-HDL cholesterol.
LDL carries cholesterol into the artery wall and is the main treatment target. HDL transports it away and is generally protective, though raising HDL with drugs has not proven useful. Triglycerides rise with refined carbohydrate, alcohol, untreated diabetes and some medications. Non-HDL cholesterol, which is total minus HDL, captures all the harmful particles together and is increasingly preferred.
Ask whether your result was fasting or non-fasting, since triglycerides in particular vary with recent meals. Some doctors also order lipoprotein(a) once in a lifetime, because it is genetically set and identifies extra risk that a standard panel misses.
What lowers LDL
Diet changes matter, though their size is often overstated:
- Replace saturated fat, such as ghee, butter, coconut oil and fatty meat, with unsaturated sources such as mustard, groundnut, rice bran or olive oil
- Add soluble fibre from oats, barley, beans, lentils, apples and psyllium husk
- Eliminate partially hydrogenated fats, still present in some bakery items and fried street food
- Eat fish twice a week, or use plant omega-3 sources such as flaxseed and walnuts
- Lose weight if you carry excess abdominal fat
- Exercise regularly, which acts mainly on triglycerides and HDL
Statins remain the most effective medication, and for people at genuinely high risk the evidence for benefit is strong. Muscle aches occur in a minority and often resolve with a change of drug or dose rather than stopping treatment altogether.
The point of treating something you cannot feel
Plaque builds over decades without symptoms and then presents suddenly. Treating a number rather than a symptom feels unusual, but it is the entire basis of preventing that first event.
This is general information. Decisions about statins or other lipid medication depend on your overall cardiovascular risk score, not the LDL value alone, so they belong with your doctor.
