What Is HDL Cholesterol? Why Good Cholesterol Matters for Heart Health

When you see HDL cholesterol on a blood report, it refers to the amount of cholesterol carried by high-density lipoprotein in your blood. HDL is commonly called “good cholesterol” because it helps carry cholesterol away from the blood vessels and back towards the liver, where it can be processed and removed.

If you are checking your cholesterol, a lipid profile test usually reports HDL along with LDL, total cholesterol and triglycerides. For older adults, these numbers are often considered together with blood pressure, blood sugar, weight, existing heart conditions and current medicines.

What Is HDL Cholesterol and What Does HDL Mean?

HDL stands for high-density lipoprotein.

To understand the HDL cholesterol meaning, think of HDL as a carrier that moves cholesterol through your bloodstream. Some cholesterol is needed by the body for normal functions. 

HDL helps transport cholesterol from tissues and blood vessel walls towards the liver. This is one reason it is often described as “good cholesterol”.

Research has found that HDL cholesterol levels are linked with cardiovascular health. However, HDL is only one part of the cholesterol picture. A person’s overall heart health depends on several factors, not just one blood test number (Barter et al., 2007).

What Is HDL Cholesterol in a Blood Test?

An HDL cholesterol blood test tells you how much HDL cholesterol is present in your blood.

It is usually reported in mg/dL on Indian laboratory reports and is commonly included in a lipid profile.

Your report may show:

The HDL number should not be read separately from the rest of the report. For example, a person may have a reasonable HDL level but still have high LDL cholesterol or high triglycerides.

This is why looking at the total cholesterol vs HDL ratio can be useful when you are trying to understand how different cholesterol numbers relate to each other.

What Are Healthy HDL Cholesterol Levels?

An HDL cholesterol level of 60 mg/dL or higher is generally considered healthy and favourable for heart health. HDL is often called “good cholesterol” because it helps transport excess cholesterol away from the arteries.

As a general reference, HDL levels are often considered more favourable when they are:

These are general reference points, not personal treatment targets.

Your doctor may interpret your HDL differently depending on your age, blood pressure, diabetes, smoking history, previous heart disease, LDL level and other health factors.

Research involving older adults has also found that low HDL is associated with a higher risk of heart-related outcomes. A study found that those in the lowest HDL group had a higher risk of ischaemic heart disease (Elgendy et al., 2023).

This does not mean that HDL alone can predict whether someone will develop heart disease. It is one part of the overall health picture.

What Does Low HDL Cholesterol Mean?

Low HDL cholesterol means your blood has less of the “good” cholesterol that helps carry excess cholesterol away from the arteries. In general, HDL below 40 mg/dL in men and below 50 mg/dL in women is considered low and may be associated with a higher risk of heart disease.

Low HDL has been associated with a higher risk of cardiovascular disease in several studies. Research found an inverse relationship between HDL cholesterol and cardiovascular mortality across different age groups, including older adults (SCORE Investigators, 2009).

“A low HDL level is one part of the cholesterol profile. We also look at LDL, triglycerides, blood pressure, blood sugar and other risk factors to understand a person’s overall cardiovascular health.”

— Dr. Bipin Gond, Zonal Medical Head, Madhavbaug

Another study found that lower HDL cholesterol was associated with a higher risk of heart attack, although the relationship between cholesterol measures and health outcomes in older adults can be different from that seen in younger people (Psaty et al., 2004).

For this reason, a low HDL result should be discussed with your doctor, especially if you also have diabetes, high blood pressure or a previous heart condition.

What Can Lower HDL Cholesterol?

Low HDL cholesterol can be linked to physical inactivity, smoking, being overweight, an unhealthy diet, diabetes and other metabolic health problems. Age and certain health conditions can also affect HDL levels. 

Several everyday factors can be linked with lower HDL levels, including:

• Lack of regular physical activity
• Smoking
• Being overweight
• Poor diet quality
• Diabetes and other metabolic health problems

Age and other health conditions can also influence cholesterol levels.

Improving your heart health through healthy food, regular activity, weight management and control of blood pressure and blood sugar is more useful.

What Does High HDL Cholesterol Mean?

High HDL cholesterol means your blood has a higher level of HDL which is often called “good cholesterol.” An HDL level of 60 mg/dL or higher is generally considered favourable and is associated with better heart health.

However, HDL is only one part of your cholesterol profile. Very high HDL levels may have different associations with health outcomes, so your HDL should be interpreted along with LDL cholesterol, triglycerides, total cholesterol and other heart health factors.

Research in older adults has found that the relationship between HDL and health outcomes can be more complex at very high levels. (Huang et al., 2019). This is why you should not try to raise your HDL number on your own through supplements or major diet changes.

If your HDL is high on a routine report, your doctor can look at it together with LDL, triglycerides, total cholesterol and your other health information.

Why Does HDL Matter After 60?

HDL matters after 60 because it helps carry excess cholesterol away from the arteries, supporting healthy blood vessels and cardiovascular health. Maintaining a healthy HDL level becomes part of protecting heart health as you age, especially when other risk factors such as high blood pressure, diabetes or high LDL cholesterol may also be present.

An HDL level of 60 mg/dL or higher is generally considered favourable. However, HDL is only one part of your cholesterol profile. After 60, your doctor may also consider LDL cholesterol, triglycerides, total cholesterol, blood pressure, blood sugar, weight and existing health conditions when assessing your heart health. The healthy range for cholesterol can also vary across different age groups, including your 30s, 40s, 50s and beyond.

Regular physical activity, a balanced diet, healthy weight and good control of blood pressure and blood sugar can help support healthy cholesterol levels and cardiovascular health after 60.

Can Lifestyle Changes Support Healthy HDL Levels?

Yes. Daily habits can support healthier cholesterol levels and overall heart health.

For many older adults, small and regular changes are easier to follow than sudden, strict changes.

A heart-friendly routine may include more vegetables, fruits, whole grains, dals and other pulses. It can also mean reducing frequent intake of deep-fried foods and foods high in unhealthy fats.

Regular movement can help as well. Depending on your health and mobility, this could include walking, gentle yoga or simple exercises recommended by your doctor.

If you smoke, stopping can also support heart health.

For senior citizens with diabetes, high blood pressure or an existing heart condition, talk to your doctor before making major changes to your diet or exercise routine. Do not stop, start or change prescribed medicines based only on your HDL cholesterol report.

When Should You Check Your HDL Cholesterol?

HDL cholesterol is usually checked as part of a lipid profile.

Your doctor may suggest checking your cholesterol if you have:

• Diabetes
• High blood pressure
• A family history of heart disease or high cholesterol
• Previous heart disease
• Previous abnormal cholesterol results
• Other cardiovascular risk factors

For older adults, keeping previous reports is also helpful. Your doctor can compare the current HDL, LDL and triglyceride results with earlier reports and understand how your cholesterol pattern has changed over time.

If you are arranging a test for an elderly parent, a family member can accompany them, help arrange the test and keep previous reports and current medicine details ready for the ayurvedic consultation.
