What is cholesterol? Basics, effects and measures for health care

Introduction

Cholesterol is a fat-like substance found in all cells in the human body. It fulfills important functions in the body and is essential for many vital processes. However, excessive cholesterol levels in the blood can lead to various health problems. In this article, we'll take a closer look at the basics of cholesterol, discuss its effects on health, and provide health care measures.

Cholesterol basics

What is cholesterol?

Cholesterol is a fat-like substance that belongs to the steroid group. It is an important component of cell membranes and plays a significant role in the production of hormones, vitamin D and bile acids. Cholesterol is both produced by the liver and absorbed through food.

LDL cholesterol and HDL cholesterol

Cholesterol is transported in the blood in the form of lipoproteins. There are different types of lipoproteins, including low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL cholesterol is often referred to as “bad” cholesterol because high LDL levels are associated with an increased risk of cardiovascular disease. HDL cholesterol is called “good” cholesterol because it helps remove excess cholesterol from the blood.

Cholesterol and nutrition

The body already produces cholesterol, so additional dietary intake is not essential. However, animal products such as meat, eggs and dairy contain cholesterol. Consuming too much cholesterol from food can increase blood cholesterol levels.

Effects of elevated cholesterol

Risk of cardiovascular disease

High blood cholesterol levels, particularly elevated LDL cholesterol levels, are an important risk factor for cardiovascular disease. When there is too much cholesterol in the blood, it can build up on the inner walls of the arteries and form plaques. These can narrow the arteries and restrict blood flow, which can lead to heart attacks and strokes.

arteriosclerosis

High cholesterol levels can lead to arteriosclerosis. This is a disease in which plaques form in the arteries due to cholesterol deposits. This can cause hardening and narrowing of the arteries, restricting blood flow and increasing the risk of cardiovascular disease.

Cholesterol stones

In some cases, excess cholesterol can lead to gallstones. Cholesterol stones occur when the bile contains too much cholesterol and it forms into crystals. Cholesterol stones can lead to gallbladder inflammation and other complications that may require medical treatment.

Health care measures

Proper nutrition

A healthy diet plays an important role in maintaining normal cholesterol levels. It is recommended to choose a diet rich in fiber, fruits and vegetables. Trans fats and saturated fats should be avoided as they can increase cholesterol levels.

Regular physical activity

Regular physical activity can help regulate cholesterol levels and reduce the risk of cardiovascular disease. Aerobic exercise such as running, swimming, and cycling are particularly effective at lowering cholesterol and improving heart health.

Avoid smoking

In addition to being harmful to the lungs, smoking can raise cholesterol levels and increase the risk of cardiovascular disease. Therefore, it is important to stop smoking or not even start.

Drug therapy

In some cases, it may be necessary to take medication to lower cholesterol levels. Statins are the most commonly prescribed medications for cholesterol control. They can lower LDL cholesterol levels and reduce the risk of cardiovascular disease. However, these medications should only be taken under medical supervision.

Frequently asked questions

1. Does cholesterol have no function in the body?

Cholesterol performs many important functions in the body, such as the production of hormones, vitamin D and bile acids. It is an essential component of cell membranes and therefore plays a crucial role in cell function.

2. Are all types of cholesterol bad for your health?

No, not all types of cholesterol are bad for your health. HDL cholesterol is considered “good” cholesterol because it helps remove excess cholesterol from the blood. LDL cholesterol, on the other hand, is often referred to as “bad” cholesterol because high levels of it are associated with an increased risk of cardiovascular disease.

3. Can you completely avoid cholesterol through your diet?

The body already produces cholesterol, so it is not necessary to completely eliminate it from the diet. However, it is advisable to limit your intake of cholesterol from animal products to maintain healthy cholesterol levels.

4. Can cholesterol levels only be regulated with medication?

No, medication is not always necessary to regulate cholesterol levels. A healthy diet, regular physical activity and avoiding smoking can also help lower cholesterol levels and reduce the risk of cardiovascular disease. However, medication may be necessary in some cases, especially if cholesterol levels remain high despite lifestyle changes.

5. At what level of cholesterol is elevated?

Elevated blood cholesterol is often defined as an LDL cholesterol level of over 130 mg/dL or a total cholesterol level of over 200 mg/dL. However, it is important to consider individual risk factors and the overall health picture to determine whether cholesterol levels are considered elevated.

Conclusion

Cholesterol is an important substance in the body that performs many vital functions. However, excessive blood cholesterol levels can lead to various health problems, especially cardiovascular disease. Therefore, it is important to take health care measures to control cholesterol levels. A healthy diet, regular physical activity, avoiding smoking and, if necessary, medication can help keep cholesterol levels at a healthy level and reduce the risk of cardiovascular disease. It is advisable to have regular examinations and speak to a doctor about individual risk factors and treatment options.
