Dyslipidemia: causes, symptoms, treatment, diet and complications

Dyslipidemia is a common condition in which the levels of fats or fat-carrying particles in the blood become abnormal. This may mean having too much LDL (“bad”) cholesterol, high triglycerides, high non-HDL cholesterol, elevated lipoprotein(a), or, in some cases, lower-than-desirable HDL cholesterol.

The condition is important because abnormal lipid levels can contribute to the gradual buildup of fatty deposits inside the arteries. Over time, this process, called atherosclerosis, can increase the risk of coronary artery disease, heart attack, stroke and peripheral artery disease. The latest 2026 American College of Cardiology/American Heart Association guideline considers dyslipidemia more broadly than simply “high cholesterol,” because several types of atherogenic particles can contribute to cardiovascular risk.

One of the tricky things about dyslipidemia is that it often causes no noticeable symptoms. A person may feel completely healthy while their cholesterol or triglycerides are gradually affecting their blood vessels. That is why a lipid profile and an assessment of overall cardiovascular risk are so important.

What is dyslipidemia?

Dyslipidemia means having an abnormal amount or balance of lipids in the blood. Lipids include cholesterol and triglycerides, which the body needs for important functions such as producing hormones, building cell membranes and storing energy.

The main measurements considered when evaluating dyslipidemia include:

• LDL cholesterol: Often called “bad” cholesterol because elevated levels can contribute to plaque formation in arteries.
• HDL cholesterol: Often called “good” cholesterol. However, current guidance emphasizes that HDL is primarily a risk marker rather than a treatment target by itself.
• Triglycerides: A type of fat used by the body for energy. High levels can increase cardiovascular risk and, when extremely elevated, can increase the risk of acute pancreatitis.
• Non-HDL cholesterol: Represents cholesterol carried by several potentially harmful lipoproteins.
• Lipoprotein(a), or Lp(a): A largely inherited lipid-related risk factor that can contribute to cardiovascular disease.

Dyslipidemia can involve one abnormal lipid measurement or several at the same time.

What is the main cause of dyslipidemia?

There is no single cause of dyslipidemia. It can result from genetics, lifestyle factors, other medical conditions or certain medicines.

Dyslipidemia is broadly divided into primary dyslipidemia and secondary dyslipidemia.

Primary dyslipidemia is usually related to inherited genetic changes that affect how the body produces, transports or removes lipids. Familial hypercholesterolemia is one example. People with inherited lipid disorders may have very high cholesterol levels even when they eat reasonably well and maintain a healthy lifestyle.

Secondary dyslipidemia develops because of another factor. Common contributors include:

• A diet high in saturated fats and highly processed foods
• Excess body weight or obesity
• Physical inactivity
• Diabetes or insulin resistance
• Hypothyroidism
• Chronic kidney disease
• Liver disease
• Excessive alcohol intake
• Certain medications
• Smoking
• Some hormonal or metabolic disorders

The National Library of Medicine notes that a sudden change or worsening in a lipid profile should prompt consideration of secondary causes such as diet, disease or medication.

So, if your cholesterol or triglycerides are unexpectedly high, it is not always enough to simply change your diet. A doctor may need to look for an underlying condition.

What are the symptoms of dyslipidemia?

Most people with dyslipidemia have no symptoms at all. This is one of the main reasons the condition can go unnoticed for years.

In many cases, dyslipidemia is discovered during a routine blood test called a lipid profile.

Severe or longstanding lipid abnormalities can sometimes produce visible signs. These may include:

• Xanthomas: Yellowish deposits of fat under the skin or around tendons.
• Xanthelasma: Yellowish cholesterol deposits around the eyelids.
• Arcus senilis: A gray or white ring around the outer edge of the cornea. It becomes more common with age but can sometimes be associated with lipid abnormalities in younger people.
• Lipemia retinalis: A rare eye finding associated with extremely high triglyceride levels.
• Symptoms of peripheral artery disease: Leg pain or cramping during walking that improves with rest.
• Angina: Chest discomfort caused by reduced blood flow to the heart.
• Symptoms of a transient ischemic attack or stroke: These occur when atherosclerosis affects blood vessels supplying the brain.

These are not symptoms that occur in everyone with dyslipidemia. In fact, most people will not have any outward signs until cardiovascular disease has already developed.

Is dyslipidemia the same as high cholesterol?

No. Dyslipidemia and high cholesterol are related, but they are not exactly the same thing.

High cholesterol generally refers to having an elevated cholesterol level, particularly LDL cholesterol. Dyslipidemia is a broader term that describes an abnormal lipid profile.

For example, a person can have:

• High LDL cholesterol
• High triglycerides
• Low HDL cholesterol
• High non-HDL cholesterol
• Elevated lipoprotein(a)
• A combination of several lipid abnormalities

Therefore, someone can have dyslipidemia even when their total cholesterol is not particularly high.

This broader understanding is reflected in the 2026 ACC/AHA dyslipidemia guideline, which covers high cholesterol, high triglycerides, elevated Lp(a) and other atherogenic particles.

How is dyslipidemia diagnosed?

Dyslipidemia is usually diagnosed with a lipid profile, a blood test that measures different types of cholesterol and triglycerides.

Depending on your age, medical history and cardiovascular risk, your healthcare professional may also consider tests such as:

• Blood glucose or HbA1c
• Thyroid function tests
• Liver function tests
• Kidney function tests
• Lipoprotein(a)
• Apolipoprotein B
• Blood pressure measurement
• Other cardiovascular risk assessments

The 2026 ACC/AHA guideline recommends measuring Lp(a) at least once in a lifetime and using selective ApoB testing when it can improve risk assessment and treatment decisions.

The important point is that there is no single cholesterol number that determines treatment for everyone. Your age, blood pressure, diabetes status, smoking history, family history and existing cardiovascular disease all influence the recommended approach.

What are the complications of dyslipidemia?

The most important complications of untreated or poorly controlled dyslipidemia are related to atherosclerosis, the buildup of plaque in the walls of arteries.

Over time, plaque can narrow arteries or become unstable and rupture, potentially causing a blood clot.

Possible complications include:

Coronary artery disease

When plaque develops in the arteries supplying the heart, blood flow can become restricted. This may cause angina and increase the risk of a heart attack.

Heart attack

If an atherosclerotic plaque ruptures and a clot blocks blood flow to part of the heart muscle, a myocardial infarction, commonly called a heart attack, can occur.

Stroke and transient ischemic attack

Dyslipidemia can contribute to plaque formation in arteries supplying the brain. If blood flow becomes blocked, it can result in an ischemic stroke. A temporary blockage may cause a transient ischemic attack (TIA).

Peripheral artery disease

Atherosclerosis can affect arteries supplying the legs. People may experience leg pain or cramping when walking, cold feet or other circulation-related symptoms.

Acute pancreatitis

Extremely high triglyceride levels can increase the risk of acute pancreatitis, a potentially serious inflammation of the pancreas.

Cardiovascular death

Severe untreated lipid abnormalities can contribute to cardiovascular disease and increase the risk of cardiovascular death. Appropriate lipid-lowering treatment can substantially reduce cardiovascular risk.

What organ does dyslipidemia affect?

Dyslipidemia does not primarily affect just one organ. Its most important long-term effects involve the blood vessels and cardiovascular system.

Excess atherogenic lipoproteins can contribute to plaque formation in arteries throughout the body. As a result, dyslipidemia can affect organs indirectly by reducing or blocking their blood supply.

The heart may be affected when coronary arteries become narrowed. The brain may be affected when arteries supplying the brain develop plaque or become blocked. The legs can be affected through peripheral artery disease.

The liver also plays a central role in lipid metabolism because it produces, processes and clears many lipoproteins. However, when people ask which organ is “affected” by dyslipidemia, the main concern is usually the cardiovascular system and the arteries rather than damage to a single organ.

What is the best treatment for dyslipidemia?

The best treatment depends on which lipid is abnormal and how much cardiovascular risk you have.

For many people, treatment begins with lifestyle changes. However, lifestyle changes are not always enough, particularly when LDL cholesterol is very high, dyslipidemia is inherited or a person already has cardiovascular disease.

The major treatment approaches include:

1. Heart-healthy eating

Reducing saturated and trans fats while eating more vegetables, fruits, whole grains, beans, legumes, nuts, seeds and healthy sources of unsaturated fat can help improve the lipid profile.

2. Regular physical activity

Exercise can support healthy cholesterol levels, improve cardiovascular fitness and help with weight management. Activities such as brisk walking, cycling, swimming and strength training can be incorporated according to individual ability.

3. Weight management

If excess weight is contributing to abnormal triglycerides or cholesterol, gradual and sustainable weight loss can improve metabolic health.

4. Medicines when appropriate

Statins remain the foundation of pharmacological treatment for many people who require lipid-lowering medication. If LDL cholesterol remains above the recommended level despite lifestyle changes and statin therapy, additional medicines such as ezetimibe, bempedoic acid or PCSK9-targeting therapies may be considered depending on the person’s risk and clinical situation.

People with severe hypertriglyceridemia may require specific treatment to reduce both cardiovascular risk and the risk of pancreatitis.

Medication should be chosen by a healthcare professional rather than started based solely on a cholesterol number.

Does dyslipidemia go away?

Sometimes it can improve substantially, but whether it completely goes away depends on the cause.

If dyslipidemia is primarily related to diet, inactivity, excess weight or another reversible factor, lipid levels may improve significantly after the underlying problem is addressed.

If an underlying condition such as hypothyroidism or diabetes is contributing, treating that condition may also improve the lipid profile.

Inherited dyslipidemias are different. Genetic conditions such as familial hypercholesterolemia generally do not disappear because the underlying genetic tendency remains. They usually require long-term monitoring and, in many cases, ongoing treatment.

Even when cholesterol numbers improve, continuing healthy habits and follow-up testing is important. Dyslipidemia is better thought of as a condition that can often be controlled rather than something that can always be permanently cured.

What is the best diet for dyslipidemia?

There is no single “dyslipidemia diet” that works identically for everyone. The most useful approach is a sustainable, heart-healthy eating pattern that reduces saturated fat and highly processed foods while increasing fiber-rich plant foods and healthy fats.

A typical plate can include:

• Plenty of vegetables
• Fresh fruit
• Whole grains such as oats, brown rice and whole-wheat products
• Beans, chickpeas, lentils and other legumes
• Nuts and seeds in appropriate portions
• Fish and other lean protein sources
• Low-fat or reduced-fat dairy where appropriate
• Unsaturated plant oils instead of butter or other sources of high saturated fat

Try to reduce foods such as:

• Fried foods
• Processed meats
• Fatty cuts of meat
• Butter and large amounts of ghee
• Full-fat dairy products
• Commercial baked goods containing saturated or trans fats
• Sugary drinks
• Excess sweets and refined carbohydrates
• Highly processed foods

The American Heart Association’s 2026 dietary guidance emphasizes vegetables, fruits, whole grains, healthy protein sources, unsaturated fats and minimally processed foods while limiting saturated fat, added sugar and excess sodium.

For people trying to lower LDL cholesterol, replacing saturated fats with unsaturated fats is particularly helpful. Foods such as nuts, seeds, fish and liquid plant oils can be useful alternatives to foods rich in saturated fat.

Fiber is also valuable. Whole grains, beans, vegetables and fruits can contribute dietary fiber, which can help improve cholesterol levels.

How to get rid of dyslipidemia?

If you have been diagnosed with dyslipidemia, the goal is not simply to “get rid of cholesterol.” Your body needs cholesterol to function. The goal is to bring harmful lipid levels into an appropriate range and reduce your long-term cardiovascular risk.

A practical approach includes:

1. Get a complete lipid profile.
2. Find out which lipid is abnormal.
3. Discuss your overall cardiovascular risk with a doctor.
4. Look for secondary causes such as diabetes, thyroid disease, kidney disease or medication effects.
5. Improve your diet, particularly by reducing saturated fat and highly processed foods.
6. Exercise regularly according to your fitness and medical status.
7. Maintain a healthy body weight.
8. Avoid tobacco products.
9. Take prescribed medication consistently if medication is recommended.
10. Repeat lipid testing when advised to see whether treatment is working.

The latest guidelines emphasize earlier management of abnormal atherogenic lipid levels because prolonged exposure over many years can increase cardiovascular risk.

Can dyslipidemia be prevented?

Not every case can be prevented. Genetic conditions can cause significant lipid abnormalities even in people who follow an excellent lifestyle.

However, many lifestyle-related contributors can be addressed.

Eating a balanced diet, remaining physically active, maintaining a healthy weight, avoiding tobacco, controlling blood pressure and diabetes, and having cholesterol checked when recommended can all help reduce cardiovascular risk.

People with a strong family history of high cholesterol or premature heart disease should speak with their healthcare professional about earlier or more frequent screening.

When should you see a doctor?

You should discuss your lipid results with a healthcare professional if your LDL cholesterol, triglycerides or other lipid measurements are elevated.

Medical evaluation is especially important if:

• Your LDL cholesterol is very high.
• You have a strong family history of early heart disease or stroke.
• You have diabetes, high blood pressure or kidney disease.
• You have already had a heart attack, stroke or peripheral artery disease.
• Your triglycerides are very high.
• You develop symptoms such as chest pain, unexplained shortness of breath or sudden neurological symptoms.

Chest pressure or pain, sudden weakness on one side of the body, difficulty speaking, sudden vision loss or other possible heart attack or stroke symptoms require urgent medical attention.

Frequently asked questions about dyslipidemia

Is dyslipidemia dangerous?

Dyslipidemia can be dangerous when it remains untreated because abnormal lipid levels can contribute to atherosclerosis and increase the risk of heart attack, stroke and peripheral artery disease. The actual risk varies considerably between individuals.

What is the main cause of dyslipidemia?

There is no single main cause. Genetics, unhealthy diet, obesity, physical inactivity, diabetes, hypothyroidism, kidney or liver disease, alcohol and certain medications can all contribute. Inherited disorders can cause severe dyslipidemia even in otherwise healthy people.

What is the best treatment for dyslipidemia?

The best treatment is individualized. It usually involves heart-healthy lifestyle changes and, when indicated by cardiovascular risk and lipid levels, cholesterol-lowering medication. Statins remain a foundation of medication-based treatment for many patients. Other lipid-lowering medicines may be added when necessary.

Is dyslipidemia the same as high cholesterol?

No. High cholesterol is one form of dyslipidemia. Dyslipidemia can also involve high triglycerides, low HDL cholesterol, elevated non-HDL cholesterol, elevated Lp(a) or combinations of these abnormalities.

Does dyslipidemia go away?

It can improve significantly when caused by modifiable factors such as diet, excess weight or physical inactivity. However, inherited forms may require lifelong management. Even when levels improve, regular monitoring is important.

What are the complications of dyslipidemia?

The major complications are atherosclerotic cardiovascular disease, coronary artery disease, heart attack, ischemic stroke and peripheral artery disease. Very high triglycerides can also increase the risk of acute pancreatitis.

What is the best diet for dyslipidemia?

A heart-healthy diet rich in vegetables, fruits, whole grains, beans, legumes, nuts, seeds, fish and unsaturated fats is generally recommended. Saturated fats, trans fats, highly processed foods and excess added sugars should be limited.

What organ does dyslipidemia affect?

Dyslipidemia mainly raises concern about the arteries and cardiovascular system. It can affect the heart, brain and legs indirectly by contributing to atherosclerotic narrowing or blockage of their blood vessels.

Can exercise lower dyslipidemia?

Regular physical activity can support healthier lipid levels and cardiovascular health. Exercise works best as part of a broader treatment plan that includes an appropriate diet, weight management and medication when needed.

Should everyone with dyslipidemia take statins?

No. Whether a statin is appropriate depends on LDL levels, existing cardiovascular disease, age, diabetes, family history and overall cardiovascular risk. A healthcare professional should determine whether medication is appropriate.

The bottom line

Dyslipidemia is more than simply having “high cholesterol.” It describes a range of abnormalities involving cholesterol, triglycerides and other lipoproteins that can increase the risk of cardiovascular disease.

The biggest challenge is that dyslipidemia often has no symptoms. You may feel perfectly well while abnormal lipid levels are contributing to plaque buildup inside your arteries.

The good news is that dyslipidemia is often manageable. A heart-healthy diet, regular physical activity, healthy weight, avoidance of tobacco and appropriate medical treatment can substantially reduce cardiovascular risk. For some people, medication is an essential part of that strategy.

If your lipid profile is abnormal, don’t focus on one number in isolation. The right treatment depends on your complete lipid profile, medical history and overall cardiovascular risk. Getting evaluated early gives you the best opportunity to control dyslipidemia before it contributes to serious complications.
