Informed by recognized medical guidance
Overview
High cholesterol is a condition where there is too much of a waxy, fat-like substance called cholesterol in your blood. It can build up in your arteries and increase your risk of heart disease and stroke.
Key facts
- High cholesterol often has no symptoms.
- A simple blood test can check your cholesterol levels.
- Workplace health programs can help you identify and manage your risk.
Yes. It is one of the most common health conditions affecting adults worldwide.
It can affect anyone, regardless of age or gender, but it becomes more common as we get older. People with a family history of high cholesterol, those who smoke, are overweight, or eat an unhealthy diet are at higher risk.
Symptoms
- Chest pain or pressure that is not relieved by rest or lasts more than a few minutes
- Difficulty breathing
- Pain in the arm, jaw, or neck
- Sudden numbness or weakness on one side of the body
- Sudden severe headache, vision problems, or difficulty speaking
- ⚠New or worsening symptoms like shortness of breath, palpitations, or dizziness — speak to a healthcare provider within the same day.
Common symptoms
- There are usually no symptoms. Many people do not know they have high cholesterol until they have a blood test.
Symptoms in children
- Rare, but some children may have a genetic condition that causes very high cholesterol, which can lead to fatty deposits under the skin or around the eyes.
Symptoms in older adults
- Same as adults — usually no symptoms. However, older adults may have a higher risk of heart attack or stroke due to cholesterol build-up.
Causes
Main causes
- Eating foods high in saturated and trans fats (like fatty meats and fried foods)
- Not being physically active enough
- Smoking
- Having a genetic condition that makes your body produce too much cholesterol (familial hypercholesterolaemia)
Risk factors
- Age over 40
- Obesity or being overweight
- Diabetes
- High blood pressure
- Family history of early heart disease
- An unhealthy diet
When to see a doctor
See a doctor urgently if:
- Chest pain or other signs of a heart attack or stroke — call emergency services immediately.
Book a routine appointment if:
- If you are over 40 and have not had a cholesterol check, ask your healthcare provider about getting one at your next appointment.
- You may also be checked as part of a workplace health screening.
Diagnosis
High cholesterol is detected with a blood test, usually after a short period of fasting. The test measures total cholesterol, LDL ('bad') cholesterol, HDL ('good') cholesterol, and triglycerides.
Tests that may be done
- Lipid panel (blood test)
- Your healthcare provider may also assess your overall heart disease risk using other factors like age, blood pressure, and family history.
What to expect at your appointment
You may be asked to fast (not eat or drink anything except water) for 9–12 hours before the test. The test is quick and involves a simple blood draw. Results are usually available within a few days.
Treatment
The main goal of treatment is to lower your risk of heart attack and stroke. This usually starts with lifestyle changes and, if needed, cholesterol-lowering medication.
Self-care at home
- Eat a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins
- Get at least 150 minutes of moderate exercise each week
- If you smoke, seek help to quit
- Keep a healthy weight
- Limit alcohol intake
Medical treatments
If lifestyle changes are not enough to lower your cholesterol to a safe level, your healthcare provider may suggest medication. Cholesterol-lowering drugs are usually taken once daily and work by helping your body remove or produce less cholesterol. Always take medications as prescribed and discuss any side effects with your doctor.
When is surgery considered?
Very rarely, some people with very high cholesterol due to genetics may need a procedure to filter cholesterol from their blood (such as apheresis) — this is used only in severe cases and is not typical.
Living with this condition
Living with high cholesterol means making long-term heart-healthy choices. Taking your medications, keeping active, and checking your cholesterol regularly can help you stay well.
Lifestyle tips
- Work with your employer to take part in workplace health screenings
- Use breaks at work to walk or stretch
- Choose healthier snacks like fruit or nuts instead of processed snacks
- Practice stress-management techniques like deep breathing or mindfulness
Diet and exercise
Focus on a Mediterranean-style diet with more vegetables, fruits, fish, nuts, and olive oil, and less red meat and processed foods. Aim for at least 30 minutes of moderate activity most days — even walking during your lunch break counts.
Mental health and emotional wellbeing
Receiving a diagnosis of high cholesterol may cause worry, but it is a manageable condition. Stress can also raise your blood pressure and indirectly affect cholesterol, so finding healthy ways to cope is important.
Prevention
In many cases, yes. A healthy diet, regular exercise, not smoking, and maintaining a healthy weight can help prevent or delay high cholesterol. Some genetic causes cannot be prevented, but they can be treated.
Screening programmes
Adults over 40 are often offered a cholesterol check by their GP. Some workplaces provide health screenings, which are a great opportunity to know your numbers.
Complications
If left untreated
- Heart disease
- Heart attack
- Stroke
- Peripheral artery disease (narrowing of leg arteries)
Long-term outlook
With the right lifestyle changes and treatment, most people with high cholesterol can greatly lower their risk of heart problems and live long, healthy lives. Regular check-ups make a big difference.
