What is cholesterol?

0

It’s a waxy, fat-like substance that is present in every cell in your body. Some is needed for your body to function. Your liver produces enough of it for your body. Sometimes it produces too much. Certain foods provide additional cholesterol, which may be more than your body needs. While some cholesterol in your blood is essential to your health, too much can be harmful. If your level is high, it increases your risk of heart disease.

Cholesterol is a soft, waxy substance found among the fats (lipids) in the bloodstream and in all the cells of your body. Cholesterol is naturally produced by your liver and helps carry fat to parts of your body that need it for energy and repairs. Cholesterol is important for your good health because it helps form cell membranes, some hormones, and other types of tissues.

Cholesterol is naturally produced by your liver and some is provided by the food you eat. When your blood cholesterol rises above the desirable level, it may build up in your arteries and may put you at increased risk for heart disease or stroke. Cholesterol levels can be high because of your diet, the amount of exercise you get, being overweight and your family history.

To understand high blood cholesterol (ko-LES-ter-ol), it is important to know more about cholesterol. • Cholesterol is a waxy, fat-like substance that is found in all cells of the body. Your body needs some cholesterol to work the right way. Your body makes all the cholesterol it needs. • Cholesterol is also found in some of the foods you eat. • Your body uses cholesterol to make hormones, vitamin D, and substances that help you digest foods. Blood is watery, and cholesterol is fatty. Just like oil and water, the two do not mix. To travel in the bloodstream, cholesterol is carried in small packages called lipoproteins (lip-o-PRO-teens). The small packages are made of fat (lipid) on the inside and proteins on the outside. Two kinds of lipoproteins carry cholesterol throughout your body. It is important to have healthy levels of both: • Low-density lipoprotein (LDL) cholesterol is sometimes called bad cholesterol. • High LDL cholesterol leads to a buildup of cholesterol in arteries.

Cholesterol is a fatty substance which is found in the blood. It is mainly made in the body. Cholesterol plays an essential role in how every cell in the body works. However, too much cholesterol in the blood can increase your risk of heart problems. LDL cholesterol and HDL cholesterol Cholesterol is carried around the body by proteins. These combinations of cholesterol and proteins are called lipoproteins. There are two main types of lipoproteins: – LDL (low-density lipoprotein) is the harmful type of cholesterol. – HDL (high-density lipoprotein) is a protective type of cholesterol. Having too much harmful cholesterol in your blood can increase your risk of getting cardiovascular disease. The risk is particularly high if you have a high level of LDL cholesterol and a low level of HDL cholesterol. Triglycerides Triglycerides are another type of fatty substance in the blood. They are found in foods such as dairy products, meat and cooking oils. They can also be produced in the body, eit
