High Cholesterol Explained

High Cholesterol Explained

What is High Cholesterol?

High cholesterol, also known as hypercholesterolemia, is a condition where there is an excessive amount of cholesterol—a waxy, fat-like substance—in the blood. Cholesterol is necessary for the production of cell membranes, certain hormones, and vitamin D. However, too much cholesterol can build up in the arteries, leading to atherosclerosis, which increases the risk of heart disease, stroke, and other cardiovascular issues.

Classifying High Cholesterol

High cholesterol is classified as a chronic condition and is often associated with an increased risk of cardiovascular diseases. It’s not a disease by itself but a risk factor for other illnesses like coronary artery disease and stroke.

Types of High Cholesterol

1. Low-Density Lipoprotein (LDL) Cholesterol: Known as “bad” cholesterol, high levels can lead to plaque buildup in the arteries.
2. High-Density Lipoprotein (HDL) Cholesterol: Known as “good” cholesterol, HDL helps remove LDL cholesterol from the arteries.
3. Triglycerides: Another type of fat in the blood, high levels of triglycerides combined with high LDL or low HDL can increase the risk of heart disease.

High Cholesterol Health Signs and Symptoms

High cholesterol typically doesn’t cause symptoms, which is why it is often referred to as a “silent” condition. However, long-term high cholesterol may lead to:

• Chest pain (angina) due to restricted blood flow to the heart.
• Fatty deposits (xanthomas) on the skin, especially around the eyes.
• Heart attack or stroke, which can be the first noticeable signs of the condition.

High Cholesterol Causes

• Genetics: Familial hypercholesterolemia is an inherited form of high cholesterol.
• Unhealthy Diet: High intake of saturated fats, trans fats, and cholesterol can increase blood cholesterol levels.
• Lack of Exercise: Physical inactivity lowers HDL and raises LDL.
• Obesity: Being overweight increases the levels of LDL and triglycerides while lowering HDL.
• Smoking: Cigarette smoking lowers HDL cholesterol and damages blood vessels.
• Other Conditions: Diabetes, kidney disease, hypothyroidism, and liver disease can all raise cholesterol levels.

High Cholesterol Stages

1. Beginner: Slightly elevated cholesterol levels (total cholesterol between 200-239 mg/dL), often manageable with lifestyle changes.
2. Medium: Moderate levels (total cholesterol between 240-299 mg/dL), may require medication in addition to lifestyle changes.
3. Advanced: Severe elevation (total cholesterol 300 mg/dL or higher), associated with a high risk of cardiovascular events and typically requires medication.

How to Prevent High Cholesterol?

• Eat a heart-healthy diet: Focus on fruits, vegetables, whole grains, and lean protein sources. Limit saturated and trans fats.
• Exercise regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
• Maintain a healthy weight: Even a small amount of weight loss can lower cholesterol levels.
• Quit smoking: Smoking cessation improves HDL cholesterol and reduces heart disease risk.
• Limit alcohol intake: Excessive drinking can raise cholesterol levels, especially triglycerides.

High Cholesterol Diagnosis

High cholesterol is diagnosed through a lipid panel or lipid profile, which measures:

• Total cholesterol
• LDL cholesterol
• HDL cholesterol
• Triglycerides

How to Test for High Cholesterol

• Blood Test (Lipid Panel): The primary test to diagnose high cholesterol. This test requires fasting for 9-12 hours beforehand.
• Advanced Lipid Testing: Measures the particle size of LDL cholesterol, which can provide more insight into cardiovascular risk.

What Type of Health Professionals Treat High Cholesterol?

• Primary Care Physicians: Often the first to diagnose and manage high cholesterol.
• Cardiologists: Specialists in heart health who manage patients with high cholesterol and cardiovascular risks.
• Endocrinologists: Manage high cholesterol related to metabolic disorders, such as diabetes.
• Dietitians/Nutritionists: Provide guidance on dietary changes to manage cholesterol levels.

Reasons to See a High Cholesterol Health Professional

• High cholesterol levels after a lipid test.
• Family history of high cholesterol or heart disease.
• Symptoms of heart disease such as chest pain, shortness of breath, or palpitations.
• Uncontrolled cholesterol levels despite lifestyle changes.

Process to Find the Right Cholesterol Specialist

• Referrals: Your primary care doctor may refer you to a cardiologist or lipid specialist.
• Research: Check credentials and expertise in managing high cholesterol and related cardiovascular conditions.
• Insurance: Ensure that the specialist is covered by your health insurance.

How to Prepare to See a Health Specialist?

• Bring your medical history: Include any family history of high cholesterol or heart disease.
• Prepare a list of medications: Include all prescriptions, over-the-counter medications, and supplements you take.
• Symptom log: Record any symptoms you experience, such as chest pain or fatigue.

What Questions to Ask a Doctor?

• What is my cholesterol level, and what does it mean?
• How can I lower my cholesterol without medication?
• Do I need to take cholesterol-lowering medications?
• What are the side effects of these medications?
• How often should I get my cholesterol checked?

What Type of Treatments Exist?

1. Lifestyle Changes: Dietary improvements, regular physical activity, and smoking cessation.
2. Medications:
   • Statins: Lower LDL cholesterol by inhibiting liver enzyme production.
   • Ezetimibe: Reduces cholesterol absorption in the intestines.
   • PCSK9 Inhibitors: Newer medications that lower LDL by increasing the liver’s ability to remove it from the blood.
   • Bile Acid Sequestrants: Help the body remove cholesterol through bile.
3. Combination Therapy: Patients with severely elevated cholesterol may require multiple medications.

High Cholesterol Clinical Trials

Ongoing clinical trials often focus on novel cholesterol-lowering drugs or treatment combinations. Examples include trials investigating new forms of PCSK9 inhibitors, gene therapy, and plant-based cholesterol management methods.

How to Monitor High Cholesterol?

• Home Cholesterol Test Kits: Provide basic cholesterol readings; however, they are not as accurate as clinical tests.
• Regular Blood Tests: Get a lipid panel every 4-6 months, or as recommended by your healthcare provider.
• Blood Pressure Monitors: High cholesterol is often associated with high blood pressure, so monitoring both is essential.

How to Manage High Cholesterol

• Medication adherence: Take cholesterol-lowering medications as prescribed.
• Diet: Follow a heart-healthy diet low in saturated fats and high in fiber.
• Exercise: Regular physical activity helps lower LDL and raise HDL cholesterol.
• Routine check-ups: Regularly visit your doctor to monitor cholesterol levels and overall heart health.

How to Care for Someone with High Cholesterol

• Encourage healthy eating: Help prepare meals low in saturated fats, trans fats, and cholesterol.
• Support an active lifestyle: Join in on daily physical activities.
• Medication management: Ensure they take their prescribed medications regularly and monitor for side effects.
