A cholesterol test can measure: When you get your result, you may just be told your total cholesterol. You might be able to
get separate results for your good and bad cholesterol, triglycerides, and your total cholesterol to HDL ratio. Ask your doctor or nurse. This is just a guide. The levels you should aim for might be different. Ask your doctor or nurse what your levels should be.
Healthy levels for different types of cholesterol. Page last reviewed: 13 July 2022 What is HDL cholesterol?HDL cholesterol is often known as ‘good cholesterol’ because it helps to protect your heart and blood vessels from disease. It’s essential for good health, but it can sometimes be too high or too low, which can lead to problems with your heart health. High HDL cholesterol Low HDL cholesterol Healthy HDL cholesterol HDL stands for high density lipoproteinLipoproteins are little parcels of lipids (fats) and proteins, which transport fats around the body in the blood. HDL cholesterol contains a lot of protein and relatively little fat. This means it’s very dense, which is why it’s called ‘high density’ lipoprotein. HDL cholesterol is one of the five main types of lipoprotein. It carries about a quarter of the cholesterol in your blood. Most of the rest is carried in LDL (low density lipoprotein) cholesterol, sometimes called ‘bad cholesterol’ as it can lead to heart disease. What are the main roles of HDL cholesterol?HDL cholesterol has a protective role against diseases of the heart and blood vessels such as heart attacks and strokes. The cholesterol itself is a fat, so it’s not the cholesterol that is protective, but the HDL lipoprotein as a whole. HDL has three main effects
What are healthy HDL cholesterol levels?Healthy HDL cholesterol levels are different for men and women. Young boys and girls have similar HDL levels, but in boys, HDL levels fall after puberty and remain lower throughout their lives.
HEART UK’s specialists believe that HDL is at its most protective at around 1.3-1.4mmol/L, and higher levels might not offer any extra protection. Note that if you have high LDL cholesterol (bad cholesterol) and your doctor is considering treatment to lower it, high HDL levels are not a reason to avoid treatment. Find out your HDL cholesterol levels with a simple cholesterol test Go How high is too high?In the past, studies showed that lower HDL levels raise the risk of diseases of the blood vessels, while high HDL levels were protective. They suggested that the lower the HDL, the higher the risk of serious events such as heart attack and stroke, and the higher the HDL, the lower the risk. This would mean that raising HDL would lower the risk of illness. More recent research suggests that HDL levels above 1.4mmol/L may not offer extra protection. In some cases, very high HDL could even raise the risk of serious problems such as a heart attack or stroke. Some studies also suggest that for people with high LDL cholesterol which is now well-controlled, raising your HDL with medicines does not lower the risk of serious problems such as heart attacks. Learn about high HDL cholesterol Go Which type of cholesterol is considered good and which type is considered bad?HDL (good) cholesterol
HDL cholesterol can be thought of as the “good” cholesterol because a healthy level may protect against heart attack and stroke. HDL carries LDL (bad) cholesterol away from the arteries and back to the liver, where the LDL is broken down and passed from the body.
Which is considered the good cholesterol HDL or LDL?LDL is also called “bad” cholesterol because it blocks your blood vessels and increases your risk for heart disease. HDL is considered “good” cholesterol because it helps protect you from heart disease. The higher your HDL, the better.
