Difference Between HDL and LDL (Good and Bad Cholesterol)

Despite having a bad reputation, cholesterol, a waxy substance that accumulates in the arteries, is not entirely harmful. In fact, some of it, once consumed in the right quantities, will even improve your health.

One of those words that we all know but do not really perceive is "cholesterol," don't you think? you have definitely heard the terms "good sterol," "bad sterol," "high cholesterol," and "low cholesterol," however you may not be quite aware of what they signify in terms of your health. In this article, we will understand the difference between HDL and LDL.

What is HDL?

Since HDL transports cholesterol to your liver, wherever it's going to be eliminated from your blood before it builds up in your arteries, it's typically accepted that HDL is "good" cholesterol.

High-density lipoproteins, or cholesterol, also are oftentimes seen as "good" as a result of they remove cholesterol from your arteries and transport it back to your liver for process and elimination. Although a typical vary is forty mg/dL to 59 mg/dL, the best healthy sterol level is sixty mg/dL (milligrams per deciliter) or above.

You run a better risk of developing heart disease once your lipoprotein levels are under 40. In very few instances, having extremely high amounts of HDL that aren't functioning properly could occur. According to doctors, some folks have a bad HDL. you have got very high levels of healthy cholesterol during this instance, but it accomplishes nothing for your body and just circulates.

What is LDL?

LDL transports cholesterol directly to your arteries. this may cause arteriosclerosis, a buildup of plaque which will probably finish in heart attack and stroke. To lower the danger of the different health problems linked to high cholesterol, it's critical monitoring this number low.

A study has shown that having high sterol from a young age increases your risks, so the more you begin monitoring this figure, the better. Our levels of bad cholesterol start off at around ten, and they keep rising as we have a tendency to age. according to epidemiological and genetic studies, people with terribly high lipoprotein levels frequently get heart attacks and strokes later in life. Your age, sex, and medical issues all affect what your ideal lipoprotein levels ought to be.

Because they deposit sterol in your arteries, low-density lipoproteins (LDL cholesterol) are regarded as the "bad" cholesterol. Your body requires a certain amount of lipoprotein and regarded as to operate effectively, however, excessive amount of total sterol might cause health problems as a result of further LDL cholesterol causes artery plaque to build up.

Similarities between HDL and LDL

  • Both good and bad cholesterol play a vital role in a person's life.

  • Both good and bad cholesterol should be balanced

  • Lipoprotein molecules are responsible for carrying both good and bad cholesterol through the blood.

  • Cardiovascular disease can be brought on by either good or bad cholesterol.

Difference between HDL and LDL

The following table highlights the major differences between HDL and LDL −


Good Cholesterol

Bad Cholesterol


A form of cholesterol known as "good cholesterol" helps the heart by removing harmful cholesterol from the circulation and storing it in the liver. HDL is another name for it

An unhealthy kind of cholesterol is referred to as "bad cholesterol" since it raises the risk of cardiovascular disease. It is also known as LDL.


Particle density of a molecule is high.

Particle density of a molecule is low.


Levels should be 60 mg/ld above

Levels should be less than 40 mg/ld


High Density lipoprotein

Low density lipoprotein


Takes LDL out of the blood, preventing the buildup of cholesterol on the walls of the arteries.

Builds up on the walls of the arteries causing atherosclerosis


Higher amounts are advantageous to health.

Lower levels are beneficial for health.

Good cholesterol (HDL) aids within the removal of different kinds of sterol from the arteries, however unhealthy sterol (LDL) accumulates within the vessel walls and ends up in vas diseases.

This is often the main distinction between smart and unhealthy sterol. To sustain glorious health, it's functionally necessary for HDL levels to be high and LDL levels to be low. The movement of sterol from the tissues to the liver for excretion by lipoprotein, as hostile the liver for deposit by lipoprotein, is another distinction between good sterol and bad cholesterol.

The medications wont to lower LDL and raise lipoprotein sterols additionally create a distinction within the difference between smart and bad cholesterol.


The two main kinds of a sterol found in blood are smart sterol and unhealthy cholesterol. compound protein molecules transport each smart and unhealthy sterol throughout the blood. Positive sterol includes a higher density than negative sterol.

Thus HDL is taken into account to be healthy sterol whereas LDL is considered to be an unhealthy sterol. within the blood artery walls, LDL coagulates into plaques. However, HDL transports such plaques into the liver once they have been Page 2 of 3 eliminated. So, the first distinction between smart cholesterol and unhealthy sterol is how every sterol functions in the blood.
