Familial Hypercholesterolemia

Disease database

Elevated LDL cholesterol levels, premature coronary artery disease, xanthomas, corneal arcus, aortic stenosis, and myocardial infarction are all terms associated with a genetic disorder known as Familial Hypercholesterolemia (FH). This condition affects the body’s ability to regulate cholesterol levels, leading to a higher risk of heart disease at an early age. In this article, we will explore the causes, symptoms, diagnosis, and treatment options for FH, as well as provide valuable insights and tips for managing this disease.

Understanding Familial Hypercholesterolemia

Familial Hypercholesterolemia is an inherited disorder that affects the way the body processes cholesterol. Cholesterol is a waxy substance that is essential for the body’s normal functioning, but when levels become elevated, it can lead to the development of fatty deposits in the arteries, increasing the risk of heart disease.

Individuals with FH have a genetic mutation that impairs the liver’s ability to remove LDL (low-density lipoprotein) cholesterol from the blood. As a result, LDL cholesterol levels remain elevated, leading to the accumulation of plaque in the arteries and increasing the risk of premature coronary artery disease.

Recognizing the Symptoms

One of the challenges with FH is that it often goes undiagnosed until a cardiovascular event occurs. However, there are some signs and symptoms that may indicate the presence of this condition:

  • Xanthomas: These are fatty deposits that appear as yellowish bumps on the skin, typically around the eyes, elbows, knees, and buttocks.
  • Corneal Arcus: A white or grayish ring that forms around the cornea of the eye.
  • Aortic Stenosis: Narrowing of the aortic valve, which can lead to chest pain, shortness of breath, and fainting.
  • Myocardial Infarction: Also known as a heart attack, this occurs when blood flow to the heart is blocked, leading to damage or death of heart muscle.

If you or a family member experience any of these symptoms, it is crucial to seek medical attention for further evaluation and testing.

Diagnosing Familial Hypercholesterolemia

Diagnosing FH involves a combination of clinical evaluation, family history assessment, and laboratory tests. A healthcare provider will typically perform a physical examination to look for physical signs of FH, such as xanthomas or corneal arcus. They will also review the patient’s family history to identify any patterns of early heart disease.

Laboratory tests, including a lipid profile and genetic testing, are essential for confirming the diagnosis. A lipid profile measures cholesterol and triglyceride levels in the blood, while genetic testing can identify specific gene mutations associated with FH.

Treatment Options and Management

While FH cannot be cured, it can be effectively managed to reduce the risk of cardiovascular events. Treatment options for FH typically involve a combination of lifestyle modifications and medication:

  • Dietary Changes: Adopting a heart-healthy diet low in saturated fats and cholesterol can help manage cholesterol levels. This includes consuming plenty of fruits, vegetables, whole grains, and lean proteins.
  • Regular Exercise: Engaging in regular physical activity can help improve cholesterol levels, strengthen the heart, and maintain a healthy weight.
  • Medication: Statins are commonly prescribed to individuals with FH to lower LDL cholesterol levels. In some cases, additional medications such as ezetimibe or PCSK9 inhibitors may be recommended.

It is important for individuals with FH to work closely with their healthcare provider to develop a personalized treatment plan that addresses their specific needs and risk factors.


Familial Hypercholesterolemia is a genetic disorder that significantly increases the risk of premature coronary artery disease. Recognizing the symptoms and seeking early diagnosis is crucial for effective management and reducing the risk of cardiovascular events. By adopting a heart-healthy lifestyle and working closely with healthcare professionals, individuals with FH can lead fulfilling lives while minimizing the impact of this condition. Remember, knowledge is power, and understanding FH empowers individuals to take control of their health and make informed decisions.
