Lowering cholesterol: lifestyle and medications at a glance
A cholesterol level that is too high is one of the most important risk factors for heart attack and stroke — and affects very many people. The treacherous part: elevated cholesterol does not hurt and often remains unnoticed for years, while it damages the blood vessels in the background. The good news: there is a lot you can do about it.
What this is about
Understanding and lowering cholesterol levels — with lifestyle and, if necessary, medications. At the centre is LDL cholesterol ("bad" cholesterol) as the main risk factor for heart attack and stroke. The target value is individual — the higher the overall risk, the lower the LDL value aimed for. The basis is lifestyle; if needed, medications add to it, above all statins.
1. What is cholesterol?
Cholesterol is a vital fat (lipid) that the body needs for many tasks: for building the cell walls, for forming hormones, vitamin D and bile acids. The body produces most of the cholesterol itself (above all in the liver); a smaller part comes from food.¹
Cholesterol is therefore nothing fundamentally bad — on the contrary, the body needs it. It only becomes a problem when too much of the "bad" cholesterol (LDL) circulates in the blood. Then it deposits in the vessel walls and promotes hardening of the arteries (atherosclerosis) — the basis of heart attack and stroke.
Because cholesterol is not water-soluble in the blood, it is transported bound to transport proteins — as so-called lipoproteins. The most important are LDL and HDL, which play quite different roles.
2. LDL and HDL: the "bad" and "good" cholesterol
Distinguishing the cholesterol transporters is central to understanding:¹
LDL cholesterol ("bad" cholesterol)
Transports cholesterol from the liver to the tissues. A high LDL value promotes deposition in the vessel walls — the most important treatable risk factor. Rule of thumb: with LDL, "the lower, the better" applies (depending on the risk).
HDL cholesterol ("good" cholesterol)
Transports excess cholesterol back to the liver. Higher HDL values tend to be regarded as favourable.
Triglycerides
Further blood lipids; high values are likewise unfavourable and often connected with diet, excess weight, alcohol and a lack of exercise.
Total cholesterol
The sum value — not very meaningful on its own, since it combines LDL and HDL.
At the centre of treatment is LDL cholesterol — it is the value that is most strongly connected with cardiovascular risk and is the most treatable. More on placing the blood-lipid values in context in the guide Understanding blood values.
3. Why high cholesterol is dangerous
Permanently high LDL cholesterol damages the blood vessels over years — usually without you feeling anything:
Atherosclerosis (hardening of the arteries): LDL deposits in the vessel walls, deposits ("plaques") form that narrow and harden the vessels
Heart attack: when a plaque in a coronary vessel ruptures and a clot closes the vessel
Stroke: through narrowed or closed brain vessels
Peripheral circulatory disorders (e.g. in the legs)
A silent course: the treacherous part is that high cholesterol causes no symptoms for a long time — the damage arises unnoticed
Precisely because high cholesterol does not hurt, it is often underestimated. But the damage to the vessels is a creeping process over years — and the earlier you counteract it, the better the risk can be lowered. That is why the control of the blood lipids is an important part of prevention.
4. When is cholesterol too high? The role of the overall risk
One of the most important messages: there is not the one "normal value" for everyone. Which LDL value is too high depends on the individual overall cardiovascular risk:¹
Low risk: in otherwise healthy people without further risk factors, higher LDL values are tolerated
High risk: in people with additional risk factors (e.g. high blood pressure, diabetes, smoking, family predisposition) or already existing cardiovascular disease, considerably lower LDL target values are aimed for
After heart attack/stroke: very low target values, to prevent renewed events
Familial hypercholesterolaemia: a hereditary form with very high values that has to be treated early and consistently
The same value — a different meaning
The question "Is my cholesterol too high?" cannot be answered across the board. The doctor estimates the individual risk (often with risk calculators) and from this derives the personal LDL target value. The same LDL value can be harmless for one person and in need of treatment for another.
5. Lowering cholesterol with lifestyle
The basis of every cholesterol therapy is lifestyle — it works for everyone, regardless of whether medications are additionally needed:
Diet: the most important lifestyle lever (its own chapter)
Weight reduction with excess weight — lowers LDL and triglycerides
Regular exercise: improves the blood-lipid values (lowers triglycerides, tends to raise HDL) and the cardiovascular risk
Stopping smoking: smoking additionally damages the vessels and lowers the "good" HDL — stopping smoking is one of the most effective steps
Reduce alcohol: above all with elevated triglycerides
Stress management and good sleep as supporting factors
Lifestyle is not just an "add-on": it lowers cholesterol and — even more important — the entire cardiovascular risk. With slightly elevated values and low risk it can sometimes be enough. With high risk it adds to the drug therapy, but usually does not replace it.
6. Diet: what really helps
With diet there are a few well-proven levers — and a few outdated notions. What really helps:
Reduce saturated fats — above all from fatty meat, sausage, fatty dairy products and many convenience products. They raise LDL more than the dietary cholesterol itself.
Avoid trans fats — in some highly processed products. Especially unfavourable.
Increase fibre — whole grains, legumes, vegetables, fruit. Certain fibres (e.g. oats) can lower LDL.
A Mediterranean diet — rich in vegetables, legumes and olive oil. Well proven for the heart.
Less sugar and alcohol — above all with elevated triglycerides.
Surprising: egg and co. are less decisive
The dietary cholesterol (e.g. in eggs) plays a smaller role for most people than long assumed — more important is the type of fats (less saturated, more unsaturated). A heart-healthy diet has a favourable effect on all blood lipids and the overall risk.
7. Statins: the most important cholesterol-lowering medications
When lifestyle is not enough or the risk is high, statins are the most important and best-studied medications for lowering cholesterol. Well-known active ingredients are atorvastatin, simvastatin, rosuvastatin and pravastatin:¹
Effect: statins inhibit an enzyme that the body needs to produce cholesterol — this lowers above all the LDL considerably
A well-proven benefit: statins demonstrably lower the risk of heart attack and stroke — especially in people with high risk or already existing cardiovascular disease
More than just lowering cholesterol: statins also have a stabilizing effect on the vessel deposits
Intake: usually once a day; some statins preferably in the evening (note the manufacturer's instructions)
Continuous therapy: statins only work as long as they are taken — after stopping, cholesterol rises again
Statins are among the most frequently prescribed and best-researched medications at all. Their benefit in preventing cardiovascular events is well proven. Nevertheless, many myths and worries surround them.
8. Myths and side effects of statins
Statins have an ambivalent reputation — similar to cortisone. An honest assessment of myths and real side effects:
Common myths in the fact check
"Statins harm more than they help": with elevated risk the well-proven benefit (fewer heart attacks/strokes) clearly outweighs the risks
"Statins destroy the muscles": muscle complaints do occur, but severe muscle damage is rare; much is treatable with a dose adjustment or a change of active ingredient
"Once on statins, always on statins": the therapy is usually long-term because cholesterol rises again after stopping — that is not "harm", but an expression of how it works
Real possible side effects
Muscle complaints (pain, weakness) — the most common side effect; usually mild and treatable, very rarely serious
Raised liver values — usually mild; the liver values are monitored
A slightly increased risk of developing diabetes — with high cardiovascular risk the benefit nevertheless outweighs it
Interactions with certain medications and with grapefruit (juice) (with some statins)
Do not stop statins on your own — raise complaints
Statins should not be stopped on your own — this raises the cardiovascular risk again. With muscle pain, unusual muscle weakness or other complaints under statins, raise it with the doctor: often a dose adjustment, a change of active ingredient or a different intake helps. Have severe, sudden muscle pain with dark urine clarified medically.
9. Further medications for lowering cholesterol
Besides statins there are further medications — usually as an addition or when statins are not enough or not tolerated:
Ezetimibe
Inhibits the absorption of cholesterol in the gut — is often combined with a statin when the LDL target is not reached alone.
PCSK9 inhibitors
Very effective, injected medications for people with very high risk or familial hypercholesterolaemia, when other agents are not enough.
Bempedoic acid
A further option, e.g. with statin intolerance.
Bile acid sequestrants
And further older agents (rarer today).
Which therapy comes into question depends on the target value, the risk and the tolerability. Often medications are combined to reach the individual LDL target. The selection and steering is done medically.
10. When medications are necessary
Whether medications are necessary is not decided by the cholesterol value alone, but by the overall risk — a medical decision:
Low risk, slightly elevated LDL: often lifestyle is enough at first
High risk (several risk factors, diabetes, advanced age): medications are often sensible, since the benefit is high
Existing cardiovascular disease (after heart attack, stroke, with CHD): statins are as a rule clearly indicated, with low target values
Familial hypercholesterolaemia: early, consistent drug therapy needed
Very high values: in need of treatment even without further risk factors
Medications are not a "defeat"
Medications do not replace a healthy lifestyle — the two complement each other. And they are not a "defeat": with high risk they are an effective prevention of serious events. The decision is made by the doctor together with you, based on your personal risk.
11. Cholesterol and CHD prevention
The actual point of lowering cholesterol is the prevention of cardiovascular diseases — above all coronary heart disease (CHD) and its consequences such as heart attack:
CHD (coronary heart disease): narrowing of the coronary vessels through atherosclerosis — high LDL is a central risk factor
Primary prevention: lowering cholesterol in people without previous cardiovascular disease, to prevent a first event (depending on the overall risk)
Secondary prevention: after an event (heart attack, stroke) — here the consistent lowering of cholesterol is especially important, with low target values
The overall package: CHD prevention includes, besides cholesterol, also blood pressure, blood sugar, stopping smoking, exercise and weight — cholesterol is an important, but not the only, building block
Lowering cholesterol is therefore not an end in itself, but part of a comprehensive cardiovascular prevention. Anyone who favourably influences several risk factors (cholesterol, blood pressure, smoking, exercise) lowers their risk the most. More on blood pressure in the guide Measuring blood pressure correctly.
brite: run statin therapy reliably
Statins only work as long as they are taken. brite reminds you punctually (some in the evening), documents LDL values over time, keeps an eye on check-up appointments and interactions — and makes the next doctor's appointment an honest review instead of a vague memory.
This cannot be answered across the board — it depends on the individual overall cardiovascular risk. At the centre is LDL cholesterol: with low risk, higher values are tolerated; with high risk (e.g. diabetes, high blood pressure, existing heart disease), considerably lower LDL target values are aimed for. The same value can be harmless for one person and in need of treatment for another. The doctor estimates your risk and sets your personal target value.
LDL is the "bad" cholesterol: it transports cholesterol to the tissues, and high values promote hardening of the arteries — it is the most important treatable risk factor (the lower, the better, depending on the risk). HDL is the "good" cholesterol: it transports excess cholesterol back to the liver, higher values are regarded as favourable. For treatment, LDL is at the centre, because it is most strongly connected with cardiovascular risk.
With slightly elevated values and low risk, lifestyle — above all diet — can sometimes be enough. It is helpful to reduce saturated fats, prefer unsaturated fats and fibre (Mediterranean diet) and to pay attention to weight, exercise and stopping smoking. With high risk or very high values, diet is usually not enough — then medications add to the lifestyle measures. The two together work best.
Statins inhibit an enzyme that the body needs to produce cholesterol — above all in the liver. This lowers LDL cholesterol considerably. In addition, they have a stabilizing effect on the deposits in the vessels. Their benefit — fewer heart attacks and strokes — is very well proven, especially in people with high risk. Statins only work as long as they are taken; after stopping, cholesterol rises again.
Statins are among the best-studied medications, and with elevated risk their well-proven benefit clearly outweighs the risks. The most common side effect is muscle complaints, which are usually mild and treatable; severe muscle damage is rare. The liver values are also monitored. Many worries around statins are exaggerated. It is important to raise complaints rather than stopping on your own — often a dose adjustment or a change of active ingredient helps.
Usually the therapy is long-term, because cholesterol rises again after stopping — the statins only lower it as long as they are taken. That is not "harm" through the medication, but an expression of how it works. Whether and when an adjustment is possible is decided by the doctor on the basis of the risk and the values. You should not stop statins on your own, since this raises the cardiovascular risk again.
Raise the complaints with your doctor rather than stopping the statin on your own. Muscle complaints are the most common side effect, usually mild. Often a dose adjustment, a change to another statin, a changed intake or a break with a renewed attempt helps. In rare cases a different cholesterol therapy can be sensible. Important: severe, sudden muscle pain together with dark urine should be clarified medically without delay.
For most people less than long assumed. The cholesterol in food (e.g. in eggs) influences the blood cholesterol value less than the type of fats. More important is to reduce saturated fats (fatty meat, sausage, fatty dairy products, convenience products) and to prefer unsaturated fats. A heart-healthy, Mediterranean diet with plenty of vegetables, legumes, olive oil and fibre is more favourable than a sole fixation on the dietary cholesterol.
That is precisely the treacherous part: high cholesterol causes no symptoms for years, but damages the vessels in the background. The LDL deposits in the vessel walls and leads to atherosclerosis — the basis of heart attack and stroke. The damage arises creepingly and unnoticed. That is why the control of the blood lipids is important, even if you feel healthy — and the earlier you counteract it, the better the risk can be lowered.
CHD stands for coronary heart disease — the narrowing of the coronary vessels through hardening of the arteries, which can lead to a heart attack. Lowering cholesterol is a central building block for preventing this: in primary prevention (before an event occurs, depending on the risk) and in secondary prevention (after an event, with low target values). Comprehensive CHD prevention includes, besides cholesterol, also blood pressure, blood sugar, stopping smoking, exercise and weight.
