Elevated blood lipids: the blood lipids in detail

The fats and accompanying substances that circulate in the blood, including triglycerides and cholesterol, have to be transported using various "shuttles" because they are insoluble in water. These lipoproteins (LDL, HDL, VLDL etc.) are divided into different fractions according to fat composition, density, place of manufacture and function. This is how a distinction is made between cholesterol in LDL and HDL lipoproteins - also known as "bad" and "good" cholesterol.

If the LDL cholesterol level is increased, this means an increased risk of deposits in the blood vessels. In the case of HDL cholesterol, on the other hand, a high level in the blood is desirable because it favors the excretion of cholesterol via the bile acids.

Cholesterol is an important building block in the body

Cholesterol is better than reputation because it is vital. Not least because of this, it is also formed in the body itself.

Cholesterol serves as an important one in the body..

• Building block for cell membranes,
• Starting material for the formation of hormones such as estrogen or testosterone,
• Starting material for the formation of vitamin D as well
• Starting material for the formation of bile acids.

The "bad" cholesterol (LDL)

The low-density lipoproteins (LDL, low-density lipoprotein) transport cholesterol to the most diverse tissues in the body where it is needed. However, increased blood levels of LDL cholesterol go hand in hand with an increased risk of arteriosclerosis.

The "good" cholesterol (HDL)

The cholesterol transported through the blood in high-density lipoproteins (HDL, high-density lipoprotein) is called “good” because this way, cholesterol that is no longer required is returned to the liver and then excreted in the bile.

Note Cholesterol occurs only in humans and animals. Plants, including vegetable oils, are free of cholesterol.

Triglycerides

These fats enter the body through food, but are also produced by the liver itself. Elevated trigyceride levels (hypertriglyceridemia) can occur in isolation or in combination with elevated cholesterol (hypercholesterolemia).
