HDL vs. LDL — What's the Difference?
By Tayyaba Rehman — Updated on September 22, 2023
HDL (High-Density Lipoprotein) is often called the "good cholesterol" as it helps remove cholesterol from the bloodstream. LDL (Low-Density Lipoprotein) is known as the "bad cholesterol" and contributes to plaque buildup in arteries.

Key Differences
HDL stands for High-Density Lipoprotein and is commonly referred to as the "good cholesterol." LDL, or Low-Density Lipoprotein, is often known as the "bad cholesterol." Both are lipoproteins that carry cholesterol through the bloodstream, but they serve very different roles.
HDL is beneficial because it removes excess cholesterol from the bloodstream and carries it back to the liver for processing. LDL, on the other hand, delivers cholesterol to the cells but can also lead to plaque formation in the arteries, which is a risk factor for cardiovascular disease.
HDL levels are usually measured to assess the risk of heart disease. Higher levels of HDL are generally considered protective against heart disease. Conversely, high levels of LDL are usually a cause for concern and are associated with an increased risk of heart disease.
HDL is often increased through exercise, a balanced diet, and sometimes medication. LDL can be managed through lifestyle changes and, in some cases, medication like statins. Both HDL and LDL levels can be checked through a simple blood test called a lipid panel.

Compare with Definitions
Hdl
HDL is an abbreviation for High-Density Lipoprotein.
My doctor said my HDL levels are excellent, which is good for my heart.
Ldl
LDL stands for Low-Density Lipoprotein.
The doctor warned me that my LDL levels are too high.
Hdl
HDL acts as a scavenger, collecting excess cholesterol.
HDL helps remove bad cholesterol from my arteries.
Ldl
LDL carries cholesterol to the cells but can lead to plaque buildup.
Elevated LDL can result in blocked arteries.
Hdl
High levels of HDL are associated with a lower risk of heart disease.
Because my HDL is high, I'm less likely to develop heart problems.
Ldl
A lipid panel blood test measures LDL among other lipids.
My lipid panel indicated that I should focus on lowering my LDL.
Hdl
A lipid panel blood test is used to measure HDL levels.
The lipid panel showed that my HDL is within a healthy range.
Ldl
High levels of LDL are a risk factor for cardiovascular disease.
I need to lower my LDL to reduce my risk of heart attacks.
Hdl
HDL levels are generally increased through exercise and a balanced diet.
Running regularly has helped raise my HDL levels.
Ldl
Statin medication is often prescribed to lower LDL levels.
My doctor prescribed statins to help lower my LDL.
Hdl
A lipoprotein with a relatively high proportion of protein and low proportion of lipids that incorporates cholesterol and transports it to the liver. High levels are associated with a decreased risk of atherosclerosis and coronary artery disease. Also called HDL cholesterol.
Ldl
A lipoprotein with a relatively high proportion of lipids and low proportion of protein that incorporates cholesterol and transports it to cells. High levels are associated with an increased risk of atherosclerosis and coronary artery disease. Also called LDL cholesterol.
Hdl
High density lipoprotein, a lipoprotein that transports cholesterol in the blood; high levels are thought to be associated with decreased risk of coronary heart disease and atherosclerosis; sometimes called good cholesterol. Contrasted with LDL.
Ldl
Low-density lipoprotein, a lipoprotein that transports cholesterol in the blood; high levels are thought to be associated with increased risk of coronary heart disease and atherosclerosis; sometimes called informally bad cholesterol.
Hdl
A lipoprotein that transports cholesterol in the blood; composed of a high proportion of protein and relatively little cholesterol; high levels are thought to be associated with decreased risk of coronary heart disease and atherosclerosis
Ldl
A lipoprotein that transports cholesterol in the blood; composed of moderate amount of protein and a large amount of cholesterol; high levels are thought to be associated with increased risk of coronary heart disease and atherosclerosis
Common Curiosities
How does HDL benefit the body?
HDL helps to remove excess cholesterol from the bloodstream.
Why is LDL considered bad?
LDL contributes to plaque buildup in the arteries, increasing heart disease risk.
What is HDL?
HDL is High-Density Lipoprotein, often called "good cholesterol."
What is LDL?
LDL is Low-Density Lipoprotein, commonly known as "bad cholesterol."
What foods are good for increasing HDL?
Foods like fish, nuts, and olive oil can increase HDL levels.
What foods should I avoid to lower LDL?
Avoid saturated fats and trans fats to lower LDL levels.
Are higher levels of HDL always better?
Generally, higher HDL levels are desirable, but extremely high levels may be a concern.
How can I increase my HDL levels?
Exercise and a balanced diet can help increase HDL levels.
Do HDL and LDL have an impact on each other?
Higher levels of HDL can help reduce the negative impact of LDL.
Can medication affect HDL and LDL?
Yes, medications like statins can lower LDL and sometimes raise HDL.
Can both HDL and LDL be managed simultaneously?
Yes, lifestyle changes and medication can manage both HDL and LDL.
How can I lower my LDL levels?
Lifestyle changes and medications like statins can lower LDL levels.
Is it sufficient to only focus on LDL for heart health?
While lowering LDL is important, optimizing HDL is also crucial for overall heart health.
How are HDL and LDL measured?
A lipid panel blood test measures both HDL and LDL levels.
Are lower levels of LDL always better?
Generally, lower LDL levels are desirable, but extremely low levels may require medical consultation.
