Why Your Blood Needs HDL Cholesterol (Know The Benefits)

Why Your Blood Needs HDL Cholesterol

Do you know why your blood needs HDL cholesterol? It is an important question to ask yourself, as HDL cholesterol plays a vital role in your health.

HDL cholesterol is one of the five major types of cholesterol found in your blood. It is usually referred to as the good cholesterol, because it works by protecting your heart and arteries.

In this blog post, we’ll discuss what HDL cholesterol does, why your body needs it, and how you can ensure you have enough.

What is HDL cholesterol and what does it do in your blood?

HDL cholesterol is also known as the good cholesterol, because it removes LDL cholesterol from the blood.

HDL cholesterol carries LDL cholesterol back to the liver, where it is broken down and eliminated.

High levels of HDL cholesterol is linked to a lower risk of heart disease and stroke.

The benefits and functions of HDL cholesterol include:

  • Reduces LDL cholesterol
  • Prevents the build-up of LDL cholesterol on the walls of blood vessels
  • Increases blood flow
  • Protects the body against inflammation and the formation of blood clots
  • Prevents the oxidation of LDL cholesterol

Is HDL cholesterol good for your blood?

Yes. Your blood needs HDL cholesterol for several reasons:

Removal of LDL cholesterol

HDL cholesterol eliminates excess LDL cholesterol from the blood. This is because LDL cholesterol can build up on the walls of blood vessels, narrowing them and increasing the risk of heart disease and stroke.

Maintaining a balance of lipoproteins

HDL cholesterol helps to maintain a balance of all the different types of lipoproteins in the blood.

High LDL cholesterol combined with low levels of HDL cholesterol is a greater risk factor for heart disease than having high levels of LDL cholesterol alone.

Antioxidant properties

HDL cholesterol has antioxidant properties which helps protect the body against inflammation and the formation of blood clots.

Immune system support

HDL cholesterol has been found to have anti-inflammatory properties and improves the activity of white blood cells helping to strengthen the immune system.

Decreased risk of cancer

High levels of HDL cholesterol is linked to a decreased risk of certain cancer types.

Better control of diabetes

HDL cholesterol helps to regulate the metabolism of glucose and insulin which helps to improve the control of diabetes.

However, the accepted level of HDL cholesterol is generally considered to be 60 milligrams per deciliter or higher. Levels below 40 mg/dL may indicate that that you have a heart disease.

What are the symptoms of low HDL cholesterol?

Low HDL cholesterol don’t cause any specific symptoms. If your HDL cholesterol is low and low density lipoproteins increases, it can lead to heart disease and stroke.

In these cases, symptoms may appear only when a damage has occurred in the heart and blood vessels, this may include:
