As a cardiologist, I often meet patients who are unsure how to interpret their lipid results or conflicting advice online. High cholesterol is one factor associated with cardiovascular disease, but misconceptions remain about how cholesterol works and how it can be managed.
Understanding the basics can help you have an informed conversation with your healthcare professional about your own cardiovascular risk.
Five Cholesterol Facts to Know
1. High cholesterol usually has no symptoms
You generally cannot feel your cholesterol level rising. A blood lipid test measures cholesterol and other blood fats and is used to assess your levels. Whether the test needs fasting depends on the tests ordered and your clinician’s advice.
2. The body makes cholesterol as well as getting it from food
The liver produces much of the cholesterol in the body, while food also contributes. The balance varies between people and can be influenced by genetics, diet, medicines, and other health factors.
3. LDL and HDL are different types of cholesterol-carrying particles
Low-density lipoprotein (LDL): Higher LDL levels can contribute to plaque buildup in artery walls, increasing cardiovascular risk.
High-density lipoprotein (HDL): HDL helps carry cholesterol from the blood and tissues back to the liver. HDL is one part of a person’s overall risk profile; a higher HDL number does not by itself remove cardiovascular risk.
4. A healthy body weight does not guarantee healthy cholesterol levels
Cholesterol levels are affected by more than body weight. Genetics, diet, activity, some medical conditions, and medicines can all play a role, so people at any body size may benefit from screening as advised by their clinician.
5. Inherited conditions can cause very high LDL
Familial hypercholesterolemia (FH) is an inherited condition that can impair the body’s ability to clear LDL cholesterol. It can cause high LDL from an early age and may require early assessment and treatment.
Evidence-Informed Ways to Manage Cholesterol
Cholesterol management is tailored to each person’s lipid levels and cardiovascular risk. Lifestyle changes can help, and medication may also be recommended when appropriate.
Dietary choices
- Limit saturated and trans fats: Reduce foods high in saturated or trans fats and replace them where practical with unsaturated-fat sources such as olive oil, nuts, seeds, and avocado.
- Choose foods with soluble fiber: Oats, barley, beans, lentils, fruit, and vegetables can be part of a heart-healthy eating pattern. Soluble fiber can help lower LDL cholesterol.
Physical activity and tobacco
- Stay physically active: Many adults are advised to aim for at least 150 minutes of moderate-intensity aerobic activity per week, as their health and ability allow. Ask your clinician what level of activity is suitable for you.
- Stop smoking: Quitting tobacco supports cardiovascular health and lowers heart and blood-vessel risk. A healthcare professional can help you find cessation support.
Medicines and clinical follow-up
If lifestyle measures alone are not enough to manage your risk, your clinician may recommend medicines such as statins. Statins reduce the liver’s cholesterol production and lower LDL cholesterol; the choice of treatment depends on your individual risk, health history, and preferences. Do not start or stop prescribed medicine without discussing it with your healthcare professional.
Schedule a Cardiovascular Evaluation
If you have a family history of early heart disease, have received an abnormal lipid result, or have questions about your blood pressure or cholesterol, discuss them with a healthcare professional. Dr. Mangesh Gaikwad can review your individual risk factors and discuss suitable next steps.
