cholesterol exercise guidance

Overview

Cholesterol is a fatty substance found in your blood. Your body needs a small amount to build healthy cells, but too much can stick to your artery walls and narrow them. This can increase your risk of heart attacks and strokes. Exercise is one of the most important ways to improve your cholesterol levels.

Yes, high cholesterol is very common. Millions of people worldwide have it, and many are unaware because it causes no symptoms in the early stages.

Anyone can have high cholesterol, but it becomes more likely as you age. It affects people of all backgrounds, genders, and body types. A family history of high cholesterol raises your risk.

Symptoms

Common symptoms

• Most people with high cholesterol have no symptoms at all.
• Very rarely, you may notice fatty bumps on your skin or tendons, especially if you have a strong family history. They can appear as yellowish patches or lumps.

Symptoms in children

• Children typically have no symptoms. In some inherited forms, fatty deposits may appear on the skin around the eyes or joints.

Symptoms in older adults

• Older adults may have no symptoms as well. However, if cholesterol has narrowed arteries, they might experience chest pain, leg pain when walking, or shortness of breath.

Causes

Main causes

• Eating a diet high in saturated fats (found in fatty meat, butter, and full-fat dairy)
• Being physically inactive
• Having an inherited condition that causes your liver to make too much cholesterol
• Being overweight or obese

Risk factors

• Age over 40 (risk increases with age)
• Smoking or exposure to tobacco smoke
• High blood pressure
• Diabetes or pre-diabetes
• A family history of early heart disease
• A diet high in processed foods and trans fats

When to see a doctor

See a doctor urgently if:

• If you have any symptoms of a heart attack or stroke, call your local emergency number immediately. Do not wait.

Book a routine appointment if:

• If you are over 40, ask your doctor about a cholesterol blood test.
• If you have a family history of high cholesterol or heart disease, talk to your doctor about earlier screening.
• If you are worried about your cholesterol or heart health, book a routine appointment.

Diagnosis

A doctor diagnoses high cholesterol using a simple blood test called a lipid panel. This test measures the different types of cholesterol and fats in your blood.

Tests that may be done

• Lipid panel (also called lipid profile)
• A blood sample from your arm, often taken after fasting for 9 to 12 hours, though some newer tests don't require fasting
• A physical exam and questions about your family history, diet, and activity level

What to expect at your appointment

The blood test takes just a few minutes. Your doctor will discuss your numbers and use them to estimate your risk of heart disease. Based on that, they'll give you advice or prescribe treatment if needed.

Treatment

Treating high cholesterol usually starts with lifestyle changes. The most powerful change is adding regular exercise to your week. You also need to eat a heart-healthy diet, manage your weight, avoid smoking, and limit alcohol. Some people also need cholesterol-lowering medication if lifestyle changes aren't enough.

Self-care at home

• Aim for at least 150 minutes of moderate aerobic activity each week, such as brisk walking, riding a bike, swimming, or dancing.
• Add strength training two or more days per week using your own body, resistance bands, or weights.
• Break your exercise into 30-minute sessions on five or more days a week, or 10-minute bursts if that's easier.
• Choose activities you enjoy so you stick with them long-term.
• Combine exercise with a balanced diet rich in fruits, vegetables, whole grains, and healthy fats like olive oil and nuts.
• Maintain a healthy weight and lose weight if your doctor advises it.

Medical treatments

If lifestyle changes aren't enough, your doctor may prescribe cholesterol-lowering medication. These medicines work in different ways to reduce how much cholesterol your body makes or absorbs. Always take them exactly as directed and talk to your doctor about any side effects. Do not stop taking them without speaking to your healthcare team.

When is surgery considered?

Surgery is rarely used for high cholesterol alone. In very severe inherited cases, a procedure called lipid apheresis might be considered. This is a way of filtering cholesterol from the blood. It is only done at specialist centers for a small number of people.

Living with this condition

Living with high cholesterol means making healthy choices a habit. It doesn't have to be perfect. Start small, be consistent, and remember that every bit of activity helps.

Lifestyle tips

• Schedule exercise like an appointment, so you don't skip it.
• Take the stairs, walk while on the phone, or park farther away to add more steps.
• Plan your meals ahead to reduce the temptation of processed foods.
• Find a friend or family member to exercise with for motivation.
• Track your activity with a phone app or simple journal.

Diet and exercise

For heart health, the NHS recommends 150 minutes of moderate aerobic activity per week, plus strength training on two or more days. Moderate activity means your heart beats faster and you can still talk, but you're slightly out of breath. Over time, this can raise your good cholesterol and lower your triglycerides, a type of fat in your blood. Pair it with a diet that includes more vegetables, fruits, beans, nuts, and whole grains, and less red meat, full-fat dairy, and fried foods.

Mental health and emotional wellbeing

Learning you have high cholesterol can be stressful. You may feel anxious about your health. Remember that this condition is manageable. Exercise can actually reduce stress and improve your mood, so focusing on physical activity can help you feel more in control.

Prevention

You can prevent or delay high cholesterol in most cases by staying physically active, eating a heart-healthy diet, not smoking, limiting alcohol, and managing stress. Some forms of high cholesterol are inherited and can't be prevented, but they can be treated.

Vaccines

There is no vaccine that prevents high cholesterol. However, staying current with recommended vaccines, such as the flu shot, can help protect your heart from infections that might make heart problems worse.

Screening programmes

Regular cholesterol screening helps catch problems early. In the UK, adults aged 40 to 74 are offered a free NHS Health Check that includes a cholesterol test. In other countries, screening recommendations vary, so ask your doctor when you should be tested.

Complications

If left untreated

• Fatty deposits build up in your arteries, narrowing them and reducing blood flow.
• A blocked artery can cause a heart attack or stroke.
• Peripheral artery disease can develop, causing leg pain and increasing the risk of limb-threatening blockages.
• Reduced blood flow can damage your heart, brain, or kidneys over time.

Long-term outlook

The outlook is very positive. Many people lower their cholesterol significantly with regular exercise and healthy eating. With medication if needed, you can protect your arteries and live a long, active life. The key is to work with your healthcare team and stay consistent.
