When it comes to heart health, many individuals have heard the term “high cholesterol.” Yet, there is often confusion surrounding the term and its relationship to another similar-sounding condition, hypercholesterolemia. Understanding these terms and their significance to cardiovascular health is important for anyone concerned about their well-being.
What Is High Cholesterol?
To begin, let’s address what high cholesterol is. Cholesterol is a type of fat (lipid) that is essential for various bodily functions. It helps to build cell membranes, produce certain hormones, and assist in the digestion of fats. Cholesterol is carried through the bloodstream by lipoproteins, which are classified into two main types:
Low-density lipoprotein (LDL), often referred to as “bad” cholesterol.
High-density lipoprotein (HDL), commonly known as “good” cholesterol.
When people refer to high cholesterol, they usually mean having an elevated level of LDL cholesterol in the bloodstream.
High LDL levels can lead to plaque buildup in the arteries, increasing the risk of heart disease, stroke, and other cardiovascular issues.
Cholesterol levels are typically measured in milligrams per deciliter (mg/dL) of blood, with the following general guidelines:
Desirable Total Cholesterol: Less than 200 mg/dL
Borderline High Total Cholesterol: 200-239 mg/dL
High Total Cholesterol: 240 mg/dL or more
High cholesterol itself is often considered a silent condition because it does not usually cause noticeable symptoms. This is why regular check-ups and blood tests are vital for identifying cholesterol imbalances.
What Is Hypercholesterolemia?
Now, let’s explore hypercholesterolemia. This term refers to a medical condition in which there is an abnormally high level of cholesterol in the blood. It is essentially a more technical and clinical way to describe high cholesterol.
Hypercholesterolemia can involve an increase in total cholesterol levels or just one of its components, most often the LDL (“bad” cholesterol).
There are two main types of hypercholesterolemia:
Primary Hypercholesterolemia: This is the most common form of the condition and is often inherited. It results from genetic mutations that cause the body to produce more cholesterol or process it less efficiently. Familial hypercholesterolemia, for example, is an inherited disorder that leads to high cholesterol levels from a young age.
Secondary Hypercholesterolemia: This type is a result of external factors like lifestyle, diet, or other medical conditions. For instance, individuals who are obese, have diabetes, or consume a diet high in saturated fats and trans fats are at a higher risk for secondary hypercholesterolemia.
Is Hypercholesterolemia The Same as High Cholesterol?
Now that we’ve defined both terms, you may be wondering: Are hypercholesterolemia and high cholesterol the same thing?
In essence, the answer is yes—they are referring to the same underlying condition: an elevated level of cholesterol in the blood.
Hypercholesterolemia is the medical term for what most people simply refer to as high cholesterol. However, there is a subtle difference in context. “High cholesterol” is a more general, everyday term used to describe the condition, while “hypercholesterolemia” is a more formal diagnosis used by healthcare professionals to refer to a cholesterol imbalance.
Both terms describe the same risk factor for cardiovascular diseases, and both require similar lifestyle changes or medical interventions to manage. If a person is diagnosed with hypercholesterolemia, they likely have high cholesterol as well.
Why Is Hypercholesterolemia/High Cholesterol Dangerous?
High cholesterol is dangerous because it can lead to plaque buildup in the arteries—a condition known as atherosclerosis.
Plaques are made up of cholesterol, fat, and other substances, and they can restrict blood flow to vital organs, including the heart and brain.
If a plaque ruptures, it can cause a blood clot to form, blocking blood flow completely and leading to serious events such as heart attacks or strokes. This is why managing cholesterol levels is a critical part of reducing cardiovascular risks.
Individuals with hypercholesterolemia are often at a higher risk for developing coronary artery disease, peripheral artery disease, and other cardiovascular conditions. The presence of high cholesterol can also contribute to other health issues such as high blood pressure and diabetes, which further increase the risk of heart disease.
Risk Factors for Hypercholesterolemia
Several risk factors can contribute to high cholesterol or hypercholesterolemia. These include:
Genetics: As mentioned earlier, familial hypercholesterolemia is an inherited condition that leads to elevated cholesterol levels.
Age and Gender: Cholesterol levels tend to increase with age, and men typically have higher cholesterol levels than women until women reach menopause.
Diet: A diet high in saturated fats, trans fats, and cholesterol can raise LDL cholesterol levels.
Obesity: Being overweight or obese can increase levels of LDL cholesterol while decreasing HDL cholesterol.
Physical Inactivity: Regular exercise helps raise HDL cholesterol and lower LDL cholesterol.
Underlying Health Conditions: Diabetes, hypothyroidism, kidney disease, and other conditions can contribute to higher cholesterol levels.
How to Manage Hypercholesterolemia or High Cholesterol
Managing high cholesterol or hypercholesterolemia typically involves a combination of lifestyle changes and, in some cases, medications.
Here are common approaches to managing the condition:
Dietary Changes:
Increase fiber intake: Foods high in soluble fiber, such as oats, beans, and fruits, can help reduce LDL cholesterol levels.
Limit unhealthy fats: Reducing intake of saturated fats (found in red meat, butter, and full-fat dairy) and eliminating trans fats (found in some processed foods) can help lower cholesterol.
Eat heart-healthy fats: Replace saturated fats with unsaturated fats found in foods like avocados, olive oil, and fatty fish.
Increase plant-based foods: A diet rich in fruits, vegetables, and whole grains can support healthy cholesterol levels.
Exercise: Engaging in regular physical activity—aiming for at least 30 minutes of moderate exercise most days of the week—can help raise HDL cholesterol and improve overall cardiovascular health.
Medications:
Statins: These are the most common drugs used to lower LDL cholesterol by inhibiting the liver’s ability to produce cholesterol.
Bile acid sequestrants: These medications bind to bile acids in the intestines, preventing the body from absorbing cholesterol.
PCSK9 inhibitors: These injectable drugs help lower LDL cholesterol, especially in individuals with genetic forms of hypercholesterolemia.
Cholesterol absorption inhibitors: These medications reduce the amount of cholesterol absorbed from the digestive tract.
Lifestyle Modifications: Other factors like quitting smoking, managing stress, and maintaining a healthy weight are crucial for managing cholesterol levels and reducing cardiovascular risks.
Conclusion
In summary, hypercholesterolemia and high cholesterol refer to the same condition—elevated cholesterol levels in the blood. However, the term “hypercholesterolemia” is the medical term, while “high cholesterol” is a more general term.
Regardless of which term you use, it is important to recognize the dangers of high cholesterol and take steps to manage it.
Lifestyle changes, medications, and regular check-ups can all play a vital role in keeping cholesterol levels in check and reducing the risk of cardiovascular diseases.
