Low-density lipoprotein (LDL) is a type of cholesterol that is found in your blood. It is often referred to as "bad" cholesterol because high levels of LDL cholesterol can increase your risk of heart disease and stroke. In contrast, high-density lipoprotein (HDL) is often referred to as "good" cholesterol because it helps to protect against heart disease.
LDL cholesterol is produced by your liver and is transported through your bloodstream by apolipoproteins. When LDL cholesterol reaches cells in your body, it is taken up by the cells and used for energy or to build new cells. However, if there is too much LDL cholesterol in your blood, it can build up in the walls of your arteries, forming plaques. These plaques can narrow the arteries and make it more difficult for blood to flow through them. This can lead to heart disease and stroke.
Now that we have a basic understanding of what LDL cholesterol is, let's take a closer look at how it can affect your health and what you can do to keep your LDL cholesterol levels in a healthy range.

LDL cholesterol is an important part of our bodies, but too much LDL cholesterol can be harmful. By understanding what LDL cholesterol is and how it can affect our health, we can take steps to keep our LDL cholesterol levels in a healthy range.
Often called "bad" cholesterol.
LDL cholesterol is often called "bad" cholesterol because high levels of LDL cholesterol can increase your risk of heart disease and stroke. This is because LDL cholesterol can build up in the walls of your arteries, forming plaques. These plaques can narrow the arteries and make it more difficult for blood to flow through them. This can lead to heart disease and stroke.
There are a number of factors that can contribute to high LDL cholesterol levels, including:
- Eating a diet high in saturated fat and cholesterol
- Being overweight or obese
- Having diabetes
- Having high blood pressure
- Smoking
- Being physically inactive
If you have high LDL cholesterol, there are a number of things you can do to lower your levels, including:
- Eating a healthy diet low in saturated fat and cholesterol
- Maintaining a healthy weight
- Getting regular exercise
- Taking medication, if necessary
It is important to keep your LDL cholesterol levels in a healthy range to reduce your risk of heart disease and stroke.
If you are concerned about your LDL cholesterol levels, talk to your doctor. Your doctor can test your cholesterol levels and help you develop a plan to lower your levels if necessary.
High levels increase heart disease risk.
High levels of LDL cholesterol can increase your risk of heart disease and stroke. This is because LDL cholesterol can build up in the walls of your arteries, forming plaques. These plaques can narrow the arteries and make it more difficult for blood to flow through them. This can lead to a number of problems, including:
- Chest pain (angina): This is a feeling of tightness, pressure, or pain in your chest. It is caused by a lack of blood flow to your heart muscle.
- Heart attack: This occurs when blood flow to your heart is completely blocked. A heart attack can be fatal.
- Stroke: This occurs when blood flow to your brain is blocked. A stroke can also be fatal.
- Peripheral artery disease (PAD): This is a condition in which the arteries in your legs or arms become narrowed or blocked. PAD can cause pain, cramping, and numbness in your legs or arms.
The higher your LDL cholesterol levels, the greater your risk of developing heart disease and stroke. Even moderately high levels of LDL cholesterol can increase your risk.
There are a number of things you can do to lower your LDL cholesterol levels and reduce your risk of heart disease and stroke, including:
- Eating a healthy diet low in saturated fat and cholesterol
- Maintaining a healthy weight
- Getting regular exercise
- Taking medication, if necessary
Talk to your doctor about your LDL cholesterol levels and what you can do to lower them.
High LDL cholesterol is a major risk factor for heart disease and stroke, but it is a risk factor that can be controlled. By making healthy lifestyle changes and taking medication if necessary, you can lower your LDL cholesterol levels and reduce your risk of these serious health problems.
Produced by liver, transported by apolipoproteins.
LDL cholesterol is produced by your liver. Once it is produced, it is transported through your bloodstream by apolipoproteins. Apolipoproteins are proteins that help cholesterol and other fats move through your bloodstream.
- LDL particles: These particles carry LDL cholesterol from your liver to cells throughout your body.
- HDL particles: These particles carry cholesterol from cells back to your liver. This cholesterol is then either removed from your body or recycled.
The balance between LDL and HDL cholesterol is important for maintaining healthy cholesterol levels. If you have too much LDL cholesterol and not enough HDL cholesterol, you are at increased risk of developing heart disease and stroke.
Used for energy or to build new cells.
LDL cholesterol is used for energy or to build new cells. When LDL cholesterol reaches cells in your body, it is taken up by the cells and used for one of two purposes:
- Energy: LDL cholesterol can be broken down and used for energy by cells throughout your body.
- Building new cells: LDL cholesterol can also be used to build new cells, such as skin cells and muscle cells.
LDL cholesterol is an essential part of your body's normal function. However, if you have too much LDL cholesterol in your blood, it can build up in the walls of your arteries, forming plaques. These plaques can narrow the arteries and make it more difficult for blood to flow through them. This can lead to heart disease and stroke.
There are a number of things you can do to keep your LDL cholesterol levels in a healthy range, including:
- Eating a healthy diet low in saturated fat and cholesterol
- Maintaining a healthy weight
- Getting regular exercise
- Taking medication, if necessary

Too much LDL can build up in artery walls.
When you have high levels of LDL cholesterol, it can build up in the walls of your arteries. This is called atherosclerosis. Over time, these deposits, called plaques, can harden and narrow the arteries. This can make it more difficult for blood to flow through the arteries and can lead to a number of health problems, including:
- Chest pain (angina): This is a feeling of tightness, pressure, or pain in your chest. It is caused by a lack of blood flow to your heart muscle.
- Heart attack: This occurs when blood flow to your heart is completely blocked. A heart attack can be fatal.
- Stroke: This occurs when blood flow to your brain is blocked. A stroke can also be fatal.
- Peripheral artery disease (PAD): This is a condition in which the arteries in your legs or arms become narrowed or blocked. PAD can cause pain, cramping, and numbness in your legs or arms.
The good news is that you can take steps to lower your LDL cholesterol levels and reduce your risk of developing these health problems. Talk to your doctor about what you can do to lower your LDL cholesterol levels.
Plaques can narrow arteries, restrict blood flow.
As LDL cholesterol builds up in the walls of your arteries, it forms plaques. These plaques are made up of fat, cholesterol, calcium, and other substances. Over time, these plaques can harden and narrow the arteries. This can make it more difficult for blood to flow through the arteries and can lead to a number of health problems, including:
- Chest pain (angina): This is a feeling of tightness, pressure, or pain in your chest. It is caused by a lack of blood flow to your heart muscle.
- Heart attack: This occurs when blood flow to your heart is completely blocked. A heart attack can be fatal.
- Stroke: This occurs when blood flow to your brain is blocked. A stroke can also be fatal.
- Peripheral artery disease (PAD): This is a condition in which the arteries in your legs or arms become narrowed or blocked. PAD can cause pain, cramping, and numbness in your legs or arms.
The good news is that you can take steps to lower your LDL cholesterol levels and reduce your risk of developing these health problems. Talk to your doctor about what you can do to lower your LDL cholesterol levels.
Can lead to heart disease and stroke.
Heart disease and stroke are the leading causes of death in the world. High LDL cholesterol is a major risk factor for both of these conditions.
- Heart disease: When LDL cholesterol builds up in the arteries that supply blood to your heart, it can lead to heart disease. This can include angina (chest pain), heart attack, and heart failure.
- Stroke: When LDL cholesterol builds up in the arteries that supply blood to your brain, it can lead to stroke. This can cause sudden weakness or numbness on one side of your body, trouble speaking or understanding speech, and vision problems.
The good news is that you can take steps to lower your LDL cholesterol levels and reduce your risk of developing heart disease and stroke. Talk to your doctor about what you can do to lower your LDL cholesterol levels.
Healthy range is below 100 mg/dL.
A healthy LDL cholesterol level is below 100 mg/dL. This means that for every deciliter of blood, there are less than 100 milligrams of LDL cholesterol.
If your LDL cholesterol level is between 100 and 129 mg/dL, you are considered to have borderline high LDL cholesterol. This means that you are at increased risk of developing heart disease and stroke.
If your LDL cholesterol level is 130 mg/dL or higher, you are considered to have high LDL cholesterol. This means that you are at high risk of developing heart disease and stroke.
There are a number of things you can do to lower your LDL cholesterol levels and reduce your risk of heart disease and stroke, including:
- Eating a healthy diet low in saturated fat and cholesterol
- Maintaining a healthy weight
- Getting regular exercise
- Taking medication, if necessary
Talk to your doctor about your LDL cholesterol levels and what you can do to lower them.
Keeping your LDL cholesterol levels in a healthy range is an important part of maintaining your overall health and reducing your risk of heart disease and stroke.
