Everything you need to know about living well with high cholesterol

Introduction

Introduction

You may be wondering, what is high cholesterol? Below, we explore what causes high cholesterol, what the symptoms of high cholesterol are, and what treatments for high cholesterol are available.

Any medical information provided here is for informational purposes and does not replace medical advice given to you by a medical professional. If you are concerned that you may have any of the high cholesterol symptoms discussed below, please see your GP.

What is high cholesterol?

Our bodies need a substance called cholesterol in order to function, and cholesterol has important roles within the body. Made in the liver, cholesterol forms the membrane of our cells. It is needed to produce vitamin D and hormones that keep us healthy and it also helps digest fats in food by making bile. Cholesterol is found in some of the foods we eat, as well as produced naturally by the body.

If we have too much cholesterol in our bodies, this can cause problems and may lead to the development of a number of serious health conditions such as stroke, coronary heart disease, heart attack, atherosclerosis or other cardiovascular conditions. Proteins carry cholesterol around the body in the bloodstream and there are two types:

High density lipoprotein (HDL)

A good type of cholesterol as it is easily removed as a waste product when it isn’t needed by the body.

Low density lipoprotein (LDL)

The bad type of cholesterol, which can build up inside arteries if there is more in the body than is required.

It is the build-up of LDL within the arteries that leads to atherosclerosis and an increased risk of strokes, heart problems and other cardiovascular disease.

There are no high cholesterol symptoms that a person may be able to detect, and a high cholesterol diagnosis is only possible by having a test via a GP. It’s important to ensure you do not have high cholesterol, to avoid other health conditions that may occur as a result.

For more information on high cholesterol, visit the Heart website.

What causes high cholesterol?

These four factors are what causes high cholesterol:

Too much saturated fat in your diet

Found in processed foods, full fat dairy and meats. Read more information on saturated fats.

Not being active enough or doing enough exercise

Meaning fats in the diet are not being used up and are, instead, stored by the body.

Smoking

Chemicals in cigarettes can stop the process of high density lipoproteins removing unused cholesterol from the body as waste, which can lead to atherosclerosis.

Familial Hypercholesterolaemia

A genetic condition that means a person has high cholesterol even from birth, and by their 20s or 30s may be at risk of heart attack or stroke. Read more information about familial hypercholesterolaemia.

Did you know
High cholesterol can lead to serious health conditions such as heart attack, stroke and heart disease, if left untreated.

Symptoms of high cholesterol

There are no symptoms of high cholesterol, which makes it impossible to know whether or not you have it. There are no high cholesterol signs to be aware of, and people of varied ages, shapes and sizes may have high cholesterol. It is a myth that only overweight people have high cholesterol, and high cholesterol levels do not relate to body fat.

Symptoms of high cholesterol

Whilst there are no high cholesterol symptoms, it’s important to get your cholesterol levels checked, try to eat healthily and get regular exercise in order to keep cholesterol levels low. Some people with consistently high cholesterol may go on to have a heart attack or develop heart disease. This is because bad cholesterol clogs and damages the interior walls of the arteries and may cause atherosclerosis. This can lead to heart failure due to the heart being put under more pressure and becoming less functional over time. Heart attacks occur when the blood supply in an artery is blocked. For more information on how high cholesterol and atherosclerosis affect the heart, visit the British Heart Foundation website.

High cholesterol can also lead to strokes, again due to arteries becoming damaged or blocked. Read more about stroke and high cholesterol risks.

Diagnosis of high cholesterol

Since there are no high cholesterol symptoms, it is good to know your cholesterol levels by getting them checked. There are home testing kits available but these are not proven to be as effective as having a test at your GP surgery or pharmacy, so the latter is usually the best option. It’s important to have cholesterol checked at age 40 and then regularly onwards. If you have a family history of high cholesterol, you should tell your GP and have regular checks, probably from an earlier age.

Cholesterol is tested via a blood test and this measures both low density lipoprotein and high density lipoprotein levels. Cholesterol is measured in millimoles per litre of blood, so your result will read in units mmol/L. You may also have levels of triglycerides tested at the same time as cholesterol – this is another fat used in the body. Read more information on how a diagnosis of high cholesterol is made.

If you are given a high cholesterol diagnosis from a healthcare professional, you may need to make lifestyle changes to reduce your cholesterol and will need to monitor your dietary cholesterol.

Read more information on high cholesterol symptoms and high cholesterol diagnosis.

Did you know
Some people are more at risk of having high cholesterol than others, depending on their age, genes, and other health conditions.
Treatments for high cholesterol

Treatments for high cholesterol

It is possible to lower cholesterol to acceptable levels by following a healthy diet for high cholesterol, increasing activity levels and possibly taking high cholesterol medications.

The high cholesterol treatment plan proposed to you by your GP, nurse or pharmacist may include tips on how to eat healthily and switch to a low cholesterol diet, as well as how much exercise you should try to get each day. This section of the guide focuses on medication treatments for high cholesterol.

Medication treatments for high cholesterol

There are a number of different types of drug medications used as high cholesterol treatments, such as:

Statins

This type of drug reduces cholesterol in the bloodstream by stopping the liver making so much cholesterol. They help people who are at risk of heart disease and often need to be taken for life. Examples include atorvastatin and simvastatin. People with familial hypercholesterolaemia often have to take statins. Learn more about statins.

Aspirin

Low doses of aspirin help reduce the risk of blood clots developing, which can cause heart attacks and strokes.

Ezetimibe

This stops cholesterol being absorbed into the blood, and has fewer side effects than statins. Learn more about ezetimibe.

Bile acid sequestrants (resins)

Used when other medications do not work, bile acid sequestrants stop the body re-absorbing bile acids, which in turn lowers cholesterol levels because one function of cholesterol is to make bile.

Fibrates

This high cholesterol treatment works by slowing the cholesterol build up in arteries to reduce the risk of heart attack, heart disease, stroke, etc.

PCSK9 inhibitors

These are new drug treatments for high cholesterol and work by stopping the PCSK9 protein being made in the liver. Usually prescribed if you have very high levels of cholesterol, or have already had a heart attack or stroke, and traditional medications are not working well enough. Read more about PCSK9 inhibitors.

LDL-apheresis

Similar to dialysis, this process filters blood through a machine to remove cholesterol and then puts it back in the body, and is usually used for people with familial hypercholesterolaemia, or who have very high cholesterol where other high cholesterol treatments are not working. Read more about LDL-apheresis.

Did you know
There are no symptoms of high cholesterol, so it’s advisable to have a cholesterol blood test regularly, especially if you are over 40 years old.

Living with high cholesterol

Receiving a high cholesterol diagnosis may be a shock to you because there are no high cholesterol symptoms that you will have noticed, and you may feel fit and healthy. You may wish to look at this as an opportunity to make some lifestyle changes to help you live healthier.

Here, we explore what living with high cholesterol may be like and how it may impact your life. We also cover the lifestyle changes, such as diet for high cholesterol and exercise for high cholesterol, that you may need to make.

Living with high cholesterol

Impact on daily living

Having a high cholesterol diagnosis may affect your day-to-day life depending on the severity of your condition and how much it is impacting your health. If a person is considered to be at risk of heart attack or stroke, or has perhaps already experienced one of these conditions as a result of high cholesterol, they may have to make drastic lifestyle changes to ensure they lower their cholesterol. Even those with slightly raised cholesterol will be advised to try and lower it by changing their diet, increasing their activity levels and making other lifestyle changes.

You may be advised to:

Eat more healthily

Following a diet for high cholesterol is really important, because saturated fat in foods we eat raise the body’s cholesterol levels. Cholesterol is contained in foods we eat but generally people are advised that high cholesterol foods do not make a big difference to blood cholesterol levels. Eating a balanced, varied and healthy diet is more important. There are lots of foods that can actually help reduce cholesterol.

Increase your exercise/activity levels

Exercise lowers levels of bad LDL cholesterol and increase good HDL cholesterol, so it helps keep the arteries and the heart healthy, as well as reducing the risk of other health conditions.

Quit smoking

Cigarettes, cigars, tobacco and shisha all contain chemicals that harm the body, making bad LDL cholesterol stick to the artery walls, and lower good HDL cholesterol levels. There is lots of support and help for quitting smoking. Read more about why smoking affects cholesterol levels. For advice on quitting smoking, visit the Smoke Free website.

Cut down on alcohol

Alcohol turns into triglycerides and cholesterol in the liver, which raises levels of these and causes liver function to decrease, resulting in the liver being unable to remove cholesterol from the body. Read more about how to cut down your alcohol intake, or stop drinking altogether.

It may help to read stories from other people living with high cholesterol.

Diet for high cholesterol

Eating a healthy, balanced diet is important if you have a high cholesterol diagnosis, and this may help to prevent high cholesterol in the first place.

Reducing your consumption of saturated fats is important, which is likely to be found in these foods:

• Biscuits, baked goods, cakes

• Chocolate

• Processed meats i.e. sausages and bacon

• Full fat dairy i.e. cheese, milk, cream, yoghurt

• Animal fats i.e. butter, ghee, lard, suet, dripping

• Meat i.e. fatty types such as lamb, beef, duck and pork

• Other oils i.e. coconut oil and palm oil

This is because saturated fat can raise blood cholesterol and make the liver less able to remove cholesterol from the body. Read about how to eat less saturated fat.

Some foods are naturally high in cholesterol, such as eggs, offal and certain types of seafood, but it’s unlikely you need to cut down on these as it will make little or no difference to your overall blood cholesterol.

Some foods actually help reduce the amount of blood cholesterol, including:

• Soya i.e. soya milk, edamame beans, soya sausages, Quorn, etc

• Nuts

• Oats

• Sterol and stanol foods i.e. Benecol yoghurts and spreads

• Fruit

• Vegetables

• Oily fish

• Avocado

• Vegetable oils i.e. olive oil, rapeseed oil

• Seeds i.e. sunflower seeds, pumpkin seeds, etc

• High fibre foods i.e. wholemeal bread and cereals, pulses, skin-on potatoes

Read more about cholesterol lowering foods.

There are lots of foods that are high in unsaturated fat, which is a better type of fat for the body, such as oily fish, nuts and avocados. Read more about fats in foods.

Some people take vitamins and minerals as supplements for high cholesterol, such as omega 3, plant sterols and garlic. You should always check with your GP or nurse before taking high cholesterol supplements.

It is possible to reduce your blood cholesterol levels through subtle dietary changes. Read this personal story about how lifestyle changes can lower cholesterol.

Read general healthy eating advice from the NHS Change4Life website.

Exercise for high cholesterol

Regular physical activity is really important to a person’s overall health and wellbeing, especially if they have high cholesterol. Exercise increases the amount of good HDL cholesterol and decreases the amount of bad LDL cholesterol. Being physically active also helps lower blood pressure and helps reduce the risk of heart problems, stroke and diabetes.

There are lots of ways to get active – you don’t have to join a gym. Adults should try to achieve 150 minutes of exercise per week.

Read more information and advice about increasing your exercise levels.

High cholesterol and employment

High cholesterol is rarely a barrier to employment but you may wish to explain your high cholesterol diagnosis to your employer. You may need to take time off occasionally for medical appointments to have your cholesterol checked or you may have side effects from medication that make your working day difficult. Many people with high cholesterol work as normal and make recommended lifestyle changes to help reduce cholesterol levels.

Did you know
Eating too much saturated fat, smoking, drinking alcohol, and getting little or no exercise can lead to high cholesterol.

Glossary

Although we always try to explain things as simply and as clearly as possible, sometimes it’s necessary to use the correct medical terminology. Medical terms are often known for being tricky to pronounce and if you’re not an expert in the subject, they can also be a little difficult to understand. Below, we’ve put together a list of terms used on this page along with a brief explanation of what they mean to help make your understanding of high cholesterol as straightforward as possible.
