High cholesterol is a common finding on routine blood tests, and it almost never causes symptoms. In most cases the first follow-up happens with the family doctor, but some situations are worth a cardiologist’s opinion: very high values, a family history of heart disease at a young age, existing heart or blood vessel disease, or treatment that is not bringing the numbers to target. A cardiologist assesses the person’s overall risk, not only the number on the lab report, and decides together with the patient what the next step should be.
What cholesterol is and how LDL differs from HDL
Cholesterol is a fatty substance the body needs to build cells and make hormones. Most of it is produced in the liver, and some comes from food. It travels in the blood inside carrier particles, and the two best-known types are LDL and HDL. LDL particles deliver cholesterol to the artery walls, and when there are too many of them over many years they contribute to the build-up of plaque that narrows the artery. That is why LDL is commonly called bad cholesterol. HDL particles work in the opposite direction and carry cholesterol back to the liver, which is why they are called good cholesterol.
A standard lipid panel usually shows four values: total cholesterol, LDL, HDL and triglycerides. The value doctors focus on most is LDL, because its link to hardening of the arteries is the most firmly established. Total cholesterol on its own is less informative, since it adds together parts that mean different things. Triglycerides matter too, mainly when they are very high or when they appear together with diabetes and excess body weight.
Why high cholesterol is silent and why it still matters
There is no pain, no fatigue and no outward sign of high cholesterol, so most people discover it by chance. Its effect accumulates slowly: plaque builds up in the artery walls over many years, and only at a late stage may it show itself as chest pain on exertion, a heart attack or a stroke. This is why cholesterol is treated as a risk factor and not as a disease in its own right. The aim of treatment is to lower the chance of an event in the future, and the benefit is greater the earlier it starts in people who are at risk.
How doctors decide whether your cholesterol needs treatment
The same LDL value can be reasonable for one person and too high for another. The decision depends on overall cardiovascular risk, which the doctor estimates from several pieces of information together. For someone who has already had a heart attack, a stent or a stroke, the target is especially low. For a young, healthy person with no other risk factors, a slightly raised value may call only for follow-up and lifestyle change.
The factors a doctor weighs when estimating risk:
- Age and sex, including menopause in women.
- Current or past smoking.
- High blood pressure and diabetes.
- Heart disease or stroke in a first-degree relative at a young age.
- Chronic kidney disease and chronic inflammatory conditions.
- Heart or blood vessel disease that has already been diagnosed.
Sometimes the risk estimate is not clear-cut, and the doctor recommends an additional test that helps refine it. A familiar example is the coronary artery calcium score, an imaging test that shows whether calcified plaque is already present in the heart’s arteries. Tests like this are done by referral, at the doctor’s discretion, and are not needed for everyone.
High cholesterol in the family: when an inherited cause is suspected
In some people cholesterol is high from a young age because of a genetic change that runs in the family, a condition called familial hypercholesterolemia. In this condition the liver struggles to clear LDL from the blood, and values are very high even in people who eat well and exercise. Suspicion rises when LDL is exceptionally high, when relatives have very high cholesterol, or when there were heart attacks in the family at a young age. Occasionally there are also fatty deposits in the skin around the eyes or on the tendons.
Identifying this condition matters because exposure to high cholesterol begins in childhood, and the risk accumulates early. When one person in a family is diagnosed, it is usual to test first-degree relatives as well, including children. This is one of the clearest situations in which a cardiology consultation adds value beyond routine follow-up.
Lifestyle or medication: how the choice is made
Lifestyle change is the foundation in every case: regular physical activity, stopping smoking, less saturated fat and processed food, more vegetables, legumes and whole grains, and weight loss where there is excess. In some people these changes lower LDL considerably, and in others the effect is modest, because much of a person’s cholesterol is set by production in the liver and by inheritance.
When overall risk is high, or when values stay above target despite real effort, the doctor will suggest medication. The most widely used medicines are statins, which reduce cholesterol production in the liver. Some patients worry about side effects, mainly muscle aches. Most people take statins without difficulty, and when a side effect does appear it is usually possible to adjust the dose, switch to a different preparation or add a medicine of another type. It is important not to stop treatment on your own but to raise the issue with your doctor, because stopping has consequences over time.
When to see a cardiologist about high cholesterol
Most people with mildly raised cholesterol are managed well by their family doctor. A cardiology consultation is particularly suitable in these situations: very high LDL or a suspected inherited cause, known heart or blood vessel disease, several risk factors together, values that do not reach target despite treatment, difficulty tolerating medication, or uncertainty about starting a treatment that is expected to continue for years. People who want an orderly assessment of their personal risk before making a decision can also benefit from such a consultation.
At the visit, the cardiologist asks about personal and family medical history, reviews blood tests and medications, measures blood pressure and examines the heart. Where needed, the cardiologist refers for further tests, explains which target suits you and builds a treatment and follow-up plan. It helps to bring blood test results from the past few years, not only the latest one, and an up-to-date medication list. Results from a health fund abroad or from a previous doctor are useful too, since the trend over time often says more than any single measurement.
Chest pain or pressure, new shortness of breath, sudden weakness on one side of the body or sudden difficulty speaking are not situations for a scheduled appointment. In those cases go to the emergency room or call emergency services immediately.
If you have received a high result and want to understand what it means for you, you can see a private cardiologist in Modi’in at EliteMed in the Ayala 360 complex, with no referral needed.

Frequently asked questions
At what level is cholesterol considered high?
There is no single number that fits everyone. The LDL target is set according to each person’s overall risk: for someone who already has heart disease or diabetes the target is much lower than for a young, healthy person. The same result may therefore call for follow-up in one person and justify treatment in another, and the doctor interprets it in light of the full picture.
Can cholesterol be lowered without medication?
In some people, yes. Physical activity, changes in eating habits, stopping smoking and losing excess weight lower LDL to a degree that varies from person to person. When overall risk is high, or when the cause is inherited, lifestyle alone is usually not enough, and the doctor will recommend adding medication.
Do I need to fast before a cholesterol test?
In most cases lipids can be measured without fasting, and the LDL result will be reliable. Fasting is needed mainly when triglycerides are high or when the doctor has specifically asked for it. If you were told to fast before the test, follow that instruction so the result can be compared with earlier ones.
Are statins a lifelong treatment?
Treatment is usually long term, because cholesterol rises again when it is stopped. The dose and the preparation can change over the years, depending on results and on changes in your health. The decision to start, continue or change treatment is made together with your doctor, and medication should not be stopped without consulting first.
Can slim, young people have high cholesterol?
Yes. Body shape does not predict cholesterol levels, and much of it is determined by inheritance. A slim, active person can have a high value, especially when there is high cholesterol or early heart disease in the family. In that case it is worth checking for an inherited cause and testing close relatives as well.
