Cholesterol is a type of fat, also called a lipid, which is found in all of your cells. It is necessary for your body to make hormones, vitamin D, and substances that help you digest foods. Your liver produces all the cholesterol your body needs.
Cholesterol is a fatty substance that occurs naturally in the human body and is essential for building cell membranes, producing certain hormones, and vitamin D. It is both produced by the body itself, primarily in the liver, and ingested through food. Cholesterol circulates in the blood in the form of lipoproteins, the two main types of which are low-density lipoprotein (LDL) and high-density lipoprotein (HDL).
Low-Density Lipoprotein (LDL-Cholesterol): This is often considered “bad” cholesterol because a high LDL cholesterol level can contribute to plaque buildup in the arteries, which can lead to atherosclerosis and cardiovascular disease.
High-Density Lipoprotein (HDL-Cholesterol): This is often considered “good” cholesterol because HDL helps to remove excess cholesterol from the blood vessels and return it to the liver for excretion.
Total Cholesterol This is the sum of both LDL and HDL cholesterol.
Triglycerides These are fats in the bloodstream, and their levels are often measured alongside cholesterol. High triglyceride levels can also contribute to the risk of cardiovascular disease. They primarily provide energy and are mainly derived from food. An excess of starches, sugars, and alcohol in the diet is also converted into triglycerides. Your body then stores these as a fat reserve.
Cholesterol is een vetachtige substantie die in je bloed wordt gevonden. Het is een essentiële component voor de opbouw van gezonde cellen, maar een te hoog cholesterolgehalte kan het risico op hart- en vaatziekten verhogen.
A high cholesterol level means there is too much cholesterol circulating in the blood, and this can increase the risk of cardiovascular disease. The total cholesterol level in the blood is a combination of different types of cholesterol, particularly LDL cholesterol (“bad” cholesterol) and HDL cholesterol (“good” cholesterol).
High cholesterol is often associated with the following characteristics:
High LDL Cholesterol An elevated level of LDL cholesterol in the blood can lead to the formation of plaque in the blood vessels, known as atherosclerosis. Atherosclerosis can cause narrowing and blockage of the blood vessels, increasing the risk of heart disease and stroke.
Low HDL Cholesterol A low level of HDL cholesterol can reduce the body's ability to remove excess cholesterol from the blood vessels, which can also increase the risk of cardiovascular disease.
According to Statista In 2018, half of the adult population in Belgium had high cholesterol. During that year, over 55 percent of Belgians in the 40 to 64 age group had cholesterol levels higher than 190 mg/dl.

Risks of high cholesterol include: * **Heart disease:** High cholesterol can lead to the buildup of plaque in your arteries, narrowing them and making it harder for blood to flow. This increases your risk of heart attack and stroke. * **Stroke:** If plaque buildup blocks blood flow to your brain, it can cause a stroke. * **Peripheral artery disease:** This is a condition where plaque narrows the arteries in your legs and feet, causing pain and discomfort when walking. * **High blood pressure:** High cholesterol can contribute to high blood pressure, which further increases your risk of heart disease and stroke. * **Gallstones:** High cholesterol can affect the composition of bile, increasing the risk of gallstones.?
ArteriosclerosisA high level of LDL cholesterol in the blood can lead to the formation of plaque on the inner walls of the blood vessels, a process known as atherosclerosis. This build-up narrows the blood vessels and restricts blood flow, which increases the risk of heart disease and strokes.
Coronary heart diseaseIf atherosclerosis occurs in the coronary arteries that supply blood to the heart, it can lead to coronary heart disease. This can cause chest pain (angina pectoris) or even lead to a heart attack.
Heart attack A high cholesterol level increases the risk of developing blood clots. If a blood clot blocks blood flow to the heart, it can lead to a heart attack. If you have had high cholesterol for a long time and are concerned about your heart, you can always make an appointment with a cardiologist.
StrokeWhen atherosclerosis occurs in the blood vessels that supply the brain, it can lead to a stroke. A stroke occurs when the blood supply to part of the brain is interrupted, which can lead to permanent damage.
Peripheral vascular diseaseNarrowing of the blood vessels in the legs due to atherosclerosis can lead to peripheral arterial disease. This can cause pain, weakness, and difficulty walking.
High blood pressure High cholesterol levels can contribute to the development of High blood pressure, which is a risk factor for cardiovascular disease in itself.
PancreatitisHigh triglyceride levels, which often go hand in hand with high cholesterol, can increase the risk of pancreatitis.
Gallstones High levels of cholesterol in the bile can promote the formation of gallstones.
De belangrijkste factoren die van invloed zijn op een hoog cholesterolgehalte zijn: * **Voeding:** Het eten van veel verzadigd en transvet kan het cholesterolgehalte verhogen. * **Overgewicht:** Overgewicht kan het cholesterolgehalte beïnvloeden. * **Gebrek aan lichaamsbeweging:** Weinig lichaamsbeweging kan leiden tot overgewicht en het cholesterolgehalte beïnvloeden. * **Roken:** Roken kan het goede cholesterol (HDL) verlagen en het slechte cholesterol (LDL) verhogen. * **Leeftijd en geslacht:** Cholesterolgehaltes kunnen naarmate we ouder worden stijgen. Bij vrouwen stijgt het cholesterolgehalte na de menopauze. * **Erfelijkheid:** Genetische factoren spelen een rol bij de aanleg voor een hoog cholesterolgehalte. * **Medische aandoeningen:** Sommige medische aandoeningen, zoals een trage schildklier, nier- of leverziekte, kunnen een hoog cholesterolgehalte veroorzaken. * **Medicatie:** Sommige medicijnen kunnen invloed hebben op uw cholesterolgehalte.?
There are several factors that can influence blood cholesterol levels. These factors can range from genetic predisposition to lifestyle choices. Here are some key influencing factors for high cholesterol:
DietFood that is rich in saturated and trans fats can increase LDL cholesterol. Foods such as fried foods, processed snacks, and foods of animal origin can contribute to high cholesterol levels.
Physical activityInsufficient exercise can lower HDL cholesterol. Regular physical activity not only helps lower LDL cholesterol but also increases HDL cholesterol.
Overweight and obesityExcess weight can contribute to higher triglyceride levels and lower HDL cholesterol levels.
SmokingSmoking can lower HDL cholesterol and damage blood vessels, making it easier for cholesterol to build up.
Age and genderCholesterol levels can vary with age and differ between men and women. As people get older, cholesterol levels often tend to increase.
GeneticsFamilial hypercholesterolaemia is an inherited condition that affects the body's ability to remove LDL cholesterol from the blood, which can lead to high cholesterol levels.
Medical conditionsCertain medical conditions, such as diabetes and hypothyroidism, can affect cholesterol levels.
Alcohol consumption: Excessive alcohol consumption can increase triglyceride levels.
Hormonal factorsHormonal changes, such as those that occur during the menopause, can affect cholesterol levels.
The good news is that in many cases you can influence your cholesterol levels. With the right steps, it is possible to improve your to lower cholesterol.
