High cholesterol living patient overview
Informed by recognized medical guidance
Overview
High cholesterol means you have too much of a waxy, fat-like substance called cholesterol in your blood. This can build up in your blood vessels and increase your risk of heart disease and stroke.
Key facts
- High cholesterol often has no symptoms, so many people don't know they have it without a blood test.
- It can run in families but is also influenced by diet, weight, and physical activity.
- With the right lifestyle changes and treatment, you can lower your cholesterol and reduce your health risks.
Yes, high cholesterol is very common. Millions of people around the world have it, and many don't even know it.
High cholesterol can affect people of all ages, including children and older adults. It's more common in people who eat a diet high in saturated fats, are overweight, don't exercise much, or have a family history of high cholesterol.
Symptoms
- Chest pain or discomfort
- Shortness of breath
- Sudden weakness or numbness on one side of the body
- Sudden trouble speaking or understanding speech
- Sudden severe headache with no known cause
- ⚠Pain, pressure, or tightness in the chest that comes and goes
- ⚠Unexplained fatigue or dizziness
- ⚠Pain in the arms, back, neck, or jaw
Common symptoms
- High cholesterol itself usually does not cause any symptoms. Most people find out they have it from a routine blood test.
Symptoms in children
- In rare cases, children with very high inherited cholesterol may develop yellowish fatty bumps on the skin called xanthomas.
Symptoms in older adults
- Older adults may also have no symptoms, but they are at higher risk for heart disease and stroke if cholesterol is uncontrolled.
Causes
Main causes
- Eating a diet high in saturated and trans fats (found in fatty meats, full-fat dairy, fried foods, and processed snacks).
- Lack of physical activity
- Being overweight or obese
- Smoking and exposure to tobacco smoke
- Heavy alcohol use
Risk factors
- Family history of high cholesterol or heart disease at a young age
- Certain medical conditions like diabetes, kidney disease, or an underactive thyroid (hypothyroidism)
- Age – risk increases as you get older
- Being male or being a woman after menopause
When to see a doctor
See a doctor urgently if:
- If you have chest pain, shortness of breath, or any signs of a heart attack or stroke (call your local emergency number).
Book a routine appointment if:
- Adults are generally advised to have their cholesterol checked every 4 to 6 years, or more often if you have risk factors.
- If you have a family history of high cholesterol or heart disease, talk to your doctor about when to start screening.
Diagnosis
High cholesterol is diagnosed with a simple blood test called a lipid profile or lipid panel, which measures total cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol, and triglycerides.
Tests that may be done
- Lipid profile (blood test) – you may need to fast for 9–12 hours before the test.
What to expect at your appointment
Your doctor will draw a small sample of blood from your arm. Results usually come back in a few days. Your doctor will explain what your numbers mean and whether you need to take steps to lower your cholesterol.
Treatment
Treatment for high cholesterol usually starts with lifestyle changes. If these aren't enough, your doctor may recommend medication. The goal is to lower your LDL cholesterol and reduce your risk of heart disease and stroke.
Self-care at home
- Eat a heart-healthy diet low in saturated and trans fats, and rich in fruits, vegetables, whole grains, and lean proteins.
- Get at least 150 minutes of moderate-intensity exercise each week (like brisk walking).
- If you smoke, seek help to quit.
- Limit alcohol to no more than 1 drink per day for women and 2 drinks per day for men (or less).
- Maintain a healthy weight.
Medical treatments
If lifestyle changes aren't enough, doctors may prescribe medications that lower cholesterol. The most common are called statins. Other medicines include bile acid sequestrants, ezetimibe, and injectable drugs called PCSK9 inhibitors. The choice depends on your cholesterol level and overall health. Always take medications exactly as prescribed and talk to your doctor about any side effects.
When is surgery considered?
Surgery is not a typical treatment for high cholesterol itself. However, if you have severe blockages from cholesterol buildup, you may need a procedure like angioplasty or bypass surgery. Your doctor will discuss this if needed.
Living with this condition
Living with high cholesterol means making healthy choices every day. You can manage it by eating well, staying active, and taking any prescribed medications. Regular check-ups with your doctor help you stay on track.
Lifestyle tips
- Cook at home more often using healthy oils like olive or canola oil.
- Choose whole grains over refined ones (for example, brown rice instead of white rice).
- Snack on fruits, vegetables, nuts, or seeds instead of processed snacks.
- Read food labels and choose products with less saturated fat and no trans fat.
Diet and exercise
Focus on a Mediterranean-style diet: plenty of vegetables, fruits, whole grains, legumes, nuts, and olive oil. Include fish at least twice a week. Limit red meat, butter, and full-fat dairy. Exercise should combine aerobic activities (walking, swimming, cycling) with strength training twice a week.
Mental health and emotional wellbeing
Being diagnosed with a chronic condition can cause stress or anxiety. It's normal to feel worried about your health. Talk to your doctor or a counselor if you feel overwhelmed. Managing stress through mindfulness, hobbies, or time with loved ones can help.
Prevention
You can't always prevent high cholesterol, especially if you have a strong family history. But for most people, a healthy lifestyle can lower your risk. Even if you have inherited high cholesterol, treatment can keep it under control.
Screening programmes
Routine blood cholesterol screening is recommended starting at age 20, or earlier if you have risk factors. Regular screening helps catch high cholesterol early so you can take steps to manage it.
Complications
If left untreated
- Narrowing of the arteries (atherosclerosis) leading to reduced blood flow
- Heart attack (myocardial infarction)
- Stroke
- Peripheral artery disease (pain or numbness in your legs)
- Angina (chest pain from reduced blood flow to the heart)
Long-term outlook
The outlook for people with high cholesterol is very good when it's managed properly. With healthy lifestyle changes and, if needed, medication, most people can lower their cholesterol and greatly reduce their risk of heart disease and stroke. It's never too late to start taking care of your heart.
