You can feel completely healthy and still have high cholesterol.
That’s one reason cholesterol screening is an important part of preventive healthcare. Unlike some health problems that cause noticeable symptoms, high cholesterol usually doesn’t give you a warning. A blood test may be the only way to find out that your cholesterol levels are higher than they should be.
The good news is that cholesterol is something you can monitor. When high levels are identified early, you and your healthcare provider can discuss lifestyle changes, treatment options, and ways to lower your long-term risk of heart disease.
What Is Cholesterol?
Cholesterol is a waxy substance that your body needs to function properly. Your body uses it to make certain hormones, vitamin D, and substances that help digest food.
Your liver produces cholesterol, and you also get it from some foods.
The problem isn’t cholesterol itself. Having too much of certain types of cholesterol in your bloodstream can increase your risk of cardiovascular disease.
That’s where regular screening comes in.
Why Is Cholesterol Screening Important?
High cholesterol often has no symptoms.
You may exercise regularly, eat a balanced diet, and feel perfectly fine while still having elevated cholesterol. Genetics, age, certain medical conditions, medications, and lifestyle factors can all influence your cholesterol levels.
A cholesterol test can identify changes that you wouldn’t necessarily notice on your own.
Knowing your numbers gives your healthcare provider an opportunity to assess your overall heart health and determine whether you need to make changes or have your cholesterol monitored more closely.
What Does a Cholesterol Test Measure?
A standard cholesterol test, often called a lipid panel or lipid profile, typically measures several different blood fats.
LDL Cholesterol
LDL is often called “bad” cholesterol because higher levels can contribute to plaque buildup in the arteries.
Over time, this buildup can narrow or block arteries and increase the risk of heart attack and stroke.
HDL Cholesterol
HDL is commonly known as “good” cholesterol. It helps transport cholesterol away from the bloodstream toward the liver, where it can be processed and removed.
Triglycerides
Triglycerides are another type of fat found in the blood. High triglyceride levels can be associated with an increased risk of cardiovascular problems, particularly when combined with other risk factors.
Total Cholesterol
Total cholesterol represents the overall amount of cholesterol in your blood and is considered alongside your other lipid measurements.
Your healthcare provider will look at these numbers together rather than relying on one result alone.
How Often Should You Get Your Cholesterol Checked?
There isn’t one testing schedule that applies to everyone.
The frequency of cholesterol screening can depend on your age, family history, existing health conditions, lifestyle, previous cholesterol results, and overall cardiovascular risk.
People with healthy cholesterol levels and a lower risk of heart disease may not need testing as frequently as people who have elevated cholesterol or are taking cholesterol-lowering medication.
If you’ve already been diagnosed with high cholesterol, your provider may recommend follow-up testing to see whether lifestyle changes or medication are working.
The best approach is to ask your healthcare provider how often you should have your cholesterol checked based on your individual risk factors.
Who May Have a Higher Risk of High Cholesterol?
Anyone can have high cholesterol, but certain factors can increase your risk.
These may include:
- Family history of high cholesterol
- Family history of heart disease
- A diet high in saturated or trans fats
- Physical inactivity
- Smoking
- Excess weight
- Diabetes
- Certain kidney or thyroid conditions
- Some medications
- Increasing age
Having one or more risk factors doesn’t mean you’ll develop heart disease. It does mean that regular preventive care may be especially important.
Can You Have High Cholesterol Without Symptoms?
Yes.
This is one of the most important things to understand about cholesterol.
High cholesterol usually doesn’t cause symptoms. You can’t reliably tell whether your cholesterol is elevated based on how you feel.
That means waiting until you experience chest pain, shortness of breath, or another concerning symptom isn’t a good strategy for monitoring cholesterol.
A simple blood test can provide information before cardiovascular disease becomes apparent.
What Can Cause High Cholesterol?
Cholesterol levels are influenced by a combination of genetics, lifestyle, and other health factors.
A diet high in saturated fats can contribute to higher LDL cholesterol. Lack of physical activity, smoking, and excess weight can also affect cardiovascular health.
Genetics matter, too. Some people inherit conditions that cause very high cholesterol even when they maintain healthy habits.
Certain medical conditions, including diabetes and hypothyroidism, may also affect cholesterol levels.
That’s why treating cholesterol isn’t always as simple as “eat better.” Your healthcare provider can help determine what’s contributing to your results.
How Can You Improve Your Cholesterol?
If your cholesterol is higher than recommended, your provider may suggest lifestyle changes.
These can include:
Eat a Heart-Healthy Diet
Focus on vegetables, fruits, whole grains, legumes, nuts, and other nutrient-rich foods. Limiting foods high in saturated fats can also help support healthier cholesterol levels.
Stay Physically Active
Regular physical activity can benefit cholesterol levels and overall cardiovascular health.
You don’t necessarily need an intense workout routine. Walking, cycling, swimming, and other activities you enjoy can help you stay active.
Maintain a Healthy Weight
If you’re overweight, even modest weight loss may benefit cholesterol and other cardiovascular risk factors.
Avoid Tobacco
Smoking damages blood vessels and increases cardiovascular risk. Quitting can have significant benefits for your heart and overall health.
Take Medication When Recommended
Lifestyle changes aren’t always enough, particularly for people with very high cholesterol or a high risk of cardiovascular disease.
If your healthcare provider recommends medication, take it as directed and discuss any concerns or side effects with them.
Cholesterol and Your Overall Heart Health
Your cholesterol number is only one piece of the cardiovascular health puzzle.
Your healthcare provider may also consider:
- Blood pressure
- Blood sugar
- Age
- Family history
- Smoking status
- Physical activity
- Weight
- Existing medical conditions
Looking at these factors together provides a more complete picture of your heart health.
Frequently Asked Questions
How do I know if I have high cholesterol?
The only reliable way to know is through a blood test. High cholesterol usually doesn’t cause noticeable symptoms.
Is high cholesterol dangerous?
High cholesterol, particularly elevated LDL cholesterol, can contribute to plaque buildup in the arteries and increase cardiovascular risk over time.
Does everyone need cholesterol screening?
Cholesterol screening is an important part of preventive healthcare, but the appropriate testing schedule varies from person to person. Your healthcare provider can recommend a schedule based on your risk factors.
Can diet lower cholesterol?
A heart-healthy eating pattern can help improve cholesterol levels for many people. However, some people may also need medication or additional treatment.
Can high cholesterol be hereditary?
Yes. Genetics can play a significant role in cholesterol levels. Some inherited conditions can cause very high cholesterol.
Don’t Wait to Check Your Numbers
High cholesterol doesn’t usually announce itself. You may feel fine while changes are quietly taking place in your cardiovascular system.
Regular cholesterol screening gives you information you can actually use. If your levels are healthy, you have a baseline to work from. If they’re elevated, you have an opportunity to address the issue with your healthcare provider.
If you haven’t had your cholesterol checked recently, ask your healthcare provider whether a lipid panel is appropriate for you. Knowing your numbers is a simple step toward taking better care of your heart.
