Hyperlipidemia means one or more types of fat in the blood are too high.
Academy topic
Hyperlipidemia
Blood fats understood through medicine and daily life.
This page explains hyperlipidemia in a calm, practical way. It starts with the main ideas. You can then learn more about blood tests, heart and blood-vessel risk, treatment, daily habits, and follow-up.
Epidemiology
High blood fats are common. They usually cause no symptoms, and many people do not know they have them.
U.S. adults
About 1 out of every 4 has low-density lipoprotein (LDL) cholesterol at or above 130 milligrams per deciliter (mg/dL).
Total cholesterol
More than 100 million people in the United States have high total cholesterol.
Inherited high cholesterol
Familial hypercholesterolemia (FH) is an inherited condition. One form, called heterozygous FH, affects about 1 out of every 250 to 300 people. Many people who have it have not been diagnosed.
Key takeaways
02
It usually causes no symptoms. A blood test called a lipid panel is the main way to find it.
03
High LDL cholesterol can build up in artery walls over time and raise the risk of heart attack and stroke.
04
Diagnosis and treatment depend on the blood-fat pattern, overall risk, family history, other health conditions, and possible other causes.
05
Treatment may include daily habit changes, medication, or both.
06
The goal is to lower long-term risk with a plan that can be checked and adjusted over time.

What is hyperlipidemia?+
Hyperlipidemia means one or more types of fat in the blood are too high. These fats are called lipids. They include cholesterol and triglycerides.
Cholesterol and triglycerides are not the same. A person may have high LDL cholesterol, high triglycerides, or both. Dyslipidemia is a broader term for any unhealthy blood-fat pattern, including low high-density lipoprotein (HDL) cholesterol.
Basic physiology+
Fats cannot travel through the blood by themselves. They move inside particles called lipoproteins.
LDL cholesterol
Low-density lipoprotein (LDL) carries most of the cholesterol in the blood. The liver removes LDL from the blood through LDL receptors.
Triglyceride-carrying particles
Chylomicrons carry triglycerides from food. Very-low-density lipoprotein (VLDL) carries triglycerides made by the liver to other parts of the body.
HDL cholesterol
High-density lipoprotein (HDL) picks up cholesterol from body tissues and helps carry it back toward the liver.
Liver
The liver helps control blood fats. It makes cholesterol and VLDL, removes leftover lipoprotein particles, and is involved in how many cholesterol-lowering medicines work.
Why it happens+
High blood fats can come from genetics, daily habits, other health conditions, medicines, or a combination of these.
family history and inherited conditions such as familial hypercholesterolemia
eating patterns high in saturated fat, trans fat, processed carbohydrates, or added sugars
physical inactivity and long periods of sitting
excess weight or insulin resistance
diabetes, metabolic syndrome, low thyroid function, kidney disease, or nephrotic syndrome
tobacco, heavy alcohol use, and certain medicines
A clinician decides when testing for an inherited condition or another cause is needed.
Symptoms and signs+
Most people with high blood fats have no symptoms. The condition is usually found with a routine lipid panel.
Very high or inherited blood-fat disorders can sometimes cause visible deposits. These may include fatty lumps over tendons, yellowish areas around the eyelids, a pale ring around the colored part of the eye, or small skin bumps. These signs are uncommon, and most people have a normal physical exam.
Sometimes the first sign is a complication, such as a heart problem, stroke, poor blood flow to the legs, or inflammation of the pancreas.
What can happen over time+
Some cholesterol-carrying particles can enter artery walls. Over time, they can help form fatty plaque. This buildup is called atherosclerosis. Risk rises when LDL cholesterol is higher and stays high for longer.
Heart
Plaque can raise the risk of chest pain, heart attack, heart muscle damage, and death from heart disease.
Brain
Plaque can raise the risk of an ischemic stroke or a temporary stroke-like event.
Blood vessels
Plaque can reduce blood flow in the legs, neck arteries, and other blood vessels.
Pancreas
Triglycerides at or above 1,000 mg/dL can be linked to sudden inflammation of the pancreas, called acute pancreatitis.
Medication and lifestyle medicine can lower heart and blood-vessel risk.
When to seek urgent care+
Seek urgent or emergency care for:
- chest pain or severe trouble breathing
- sudden weakness, numbness, facial droop, trouble speaking, or another possible stroke symptom
- severe illness that may be acute pancreatitis, especially when triglycerides are very high
Do not try to manage a possible heart attack, stroke, or acute pancreatitis at home.
How hyperlipidemia is diagnosed+
Diagnosis starts with a blood test called a lipid panel. It usually reports total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, and non-HDL cholesterol. Non-HDL cholesterol is total cholesterol minus HDL cholesterol.
Most screening tests do not require fasting. A fasting test is preferred when triglycerides need a closer look, when triglycerides are above 400 mg/dL, or when a clinician wants a fasting starting result.
The numbers are interpreted with the person's overall heart and blood-vessel risk. A clinician may also review family history, other possible causes, and selected tests. These may include lipoprotein(a), apolipoprotein B, or a computed tomography (CT) scan that measures calcium in heart arteries.
| Finding | What it may mean |
|---|---|
| LDL cholesterol at or above 190 mg/dL | This is very high and should prompt an evaluation for familial hypercholesterolemia. |
| Triglycerides at or above 500 mg/dL | This is severe hypertriglyceridemia, meaning triglycerides are very high. |
| Triglycerides at or above 1,000 mg/dL | This level is linked to acute pancreatitis. |
Living with hyperlipidemia+
After medication is started or changed, a lipid panel is often repeated in 4 to 12 weeks. Once treatment and blood-fat levels are stable, follow-up is often every 6 to 12 months. A 12-month interval may be appropriate for some stable patients.
Follow-up may include medication use and side effects, food and movement, weight, blood pressure, blood sugar, new symptoms, other health conditions, cost, and access to care.
Medication treatment+
Statins are the first-choice medicines for lowering LDL cholesterol. Other medicines may be added or used in selected situations. The choice depends on the blood-fat pattern, overall risk, response, side effects, and safety. The full Treatment section explains how medication and daily habits work together.
Lifestyle treatment+
Daily habits are a foundation of care for unhealthy blood-fat levels. They remain important before, during, and after medication treatment. The full Treatment section explains the main areas to consider.
Questions to ask your physician+
- What do my cholesterol and triglyceride results mean?
- What is my short- and long-term risk for heart and blood-vessel disease?
- Could another health condition, medicine, or substance be affecting my results?
- Should I be checked for familial hypercholesterolemia?
- Do I need a lipoprotein(a) test or an apolipoprotein B test?
- Would a heart-artery calcium scan help with my treatment decision?
- Do I need medication now?
- Which medicines fit my risk, other health conditions, and preferences?
- Which food and movement changes matter most for my results?
- What should I know about sleep, stress, tobacco, alcohol, and supplements?
- When should my lipid panel be repeated?
- What symptoms or side effects should prompt a call or urgent care?
Frequently asked questions+
Can I have hyperlipidemia if I feel fine?
Yes. High blood fats usually cause no symptoms. A lipid panel is the main way to find them.
Do I need to fast before a lipid panel?
Not always. Most screening can use a nonfasting test. Fasting is preferred when triglycerides need a closer look, when they are above 400 mg/dL, or when a clinician wants a fasting starting result.
Will daily habit changes be enough?
Sometimes they may be the first treatment. Many people also need medication. The decision depends on LDL cholesterol, triglycerides, overall risk, and other health conditions.
What if I develop muscle symptoms while taking a statin?
Tell the prescribing clinician. The clinician may review when the symptoms started, how severe they are, whether another cause is possible, and what happened during any earlier statin trials. A blood test for muscle injury is used only in selected situations.
Are store-bought fish oil or red yeast rice the same as prescription treatment?
No. Store-bought fish oil has not been shown to lower heart and blood-vessel events. A prescription medicine called icosapent ethyl has shown benefit in selected patients. Red yeast rice products can vary in strength and quality and are not regulated as medicines by the U.S. Food and Drug Administration.
Treatment
Two pillars, one plan.
Contrada treats high blood fats through traditional medicine and lifestyle medicine together. The balance depends on the blood-fat pattern, overall risk, other health conditions, safety, feasibility, and physician judgment.
Traditional medicine treatment
Measure risk, choose treatment, and follow the response.
Care may include a lipid panel, a review of heart and blood-vessel risk, and testing for inherited or other causes. Selected people may need additional blood tests or a heart-artery calcium scan. Medication and follow-up are added when appropriate.
Statins are the first-choice medicines for lowering LDL cholesterol. Other medicine groups used in selected situations include:
- ezetimibe, which lowers cholesterol absorbed from the intestine
- antibody medicines that help the liver remove more LDL cholesterol
- inclisiran, which also helps the liver remove more LDL cholesterol
- bempedoic acid, which lowers cholesterol production in the liver
- bile acid sequestrants, which lower LDL cholesterol but may raise triglycerides
- selected triglyceride-lowering medicines, including icosapent ethyl, fibrates, and prescription omega-3 fatty acids
Medication choice should consider the person's risk, pregnancy, kidney and liver function, diabetes, human immunodeficiency virus (HIV) medicines, side effects, cost, ability to follow the plan, and preferences.
Lifestyle medicine treatment
Daily life as part of the treatment plan.
Lifestyle medicine should be practical, safe, and matched to the person and blood-fat pattern.
Nutrition
Mediterranean, Dietary Approaches to Stop Hypertension (DASH), vegetarian, vegan, and Portfolio-style eating patterns may improve blood fats. Replacing saturated fat with unsaturated fat, eating more soluble fiber and plant protein, and limiting processed carbohydrates and added sugars may help.
Movement
Aerobic activity, strength training, and less sitting can improve blood fats and heart health.
Sleep
Sleep length, sleep quality, insomnia, and obstructive sleep apnea belong in a full heart-risk review.
Stress and recovery
Ongoing stress, depression, anxiety, and related barriers can affect heart risk and the ability to follow treatment.
Relationships and community
Support, food access, transportation, the ability to understand health information, affordability, and access to care can affect whether a plan is realistic.
Substances
Tobacco raises heart and blood-vessel risk. Heavy alcohol use can raise triglycerides and pancreatitis risk. People with high triglycerides are advised to avoid alcohol. Evidence about cannabis remains limited and conflicting. Medicines and supplements should also be reviewed.
Very high triglycerides may require strict limits on dietary fat, alcohol, and added sugars. Care from a lipid specialist and registered dietitian nutritionist is strongly recommended in severe cases.
