Have you ever reviewed your blood test results and noticed your cholesterol is too high? Or perhaps your doctor has mentioned, “Your ‘bad’ cholesterol is a bit elevated, and you need to get it under control”? You are certainly not alone—this is a very common experience for many. Today, at Nirogi Lanka, we are going to discuss Hypercholesterolemia. Put simply, this condition means the level of “bad” cholesterol in your body—known as Low-Density Lipoprotein (LDL)—has risen above the healthy range.
What exactly is Hypercholesterolemia? Let's break it down!
To be more precise, Hypercholesterolemia is a type of lipid disorder where the amount of LDL cholesterol in your blood becomes dangerously high. Think of LDL as excess fat that gradually builds up on the inner walls of your arteries. It’s very similar to how rust accumulates inside an old water pipe. This process is medically known as Atherosclerosis.
Imagine the plumbing in your garden: if sediment builds up inside the pipes, it restricts the flow of water. When blood vessels become clogged with fatty deposits, your blood circulation is severely hampered.
This Atherosclerosis is exactly why your risk for life-threatening conditions like heart attacks and strokes increases significantly. In fact, cardiovascular disease is the leading cause of death globally, and Atherosclerosis is a primary contributor to this.
What levels are considered Hypercholesterolemia?
You might be wondering, “At what point does my cholesterol level officially become Hypercholesterolemia?” Your doctor determines this not just by looking at your LDL number, but by weighing it against your other risk factors for cardiovascular disease.
Generally, these are the thresholds where LDL cholesterol is considered high:
- If you have no other risk factors, an LDL level of 190 mg/dL or higher.
- If you have one major risk factor, an LDL level above 160 mg/dL.
- If you have two or more risk factors, an LDL level above 130 mg/dL.
Depending on your personal heart disease risk, doctors may recommend keeping your LDL cholesterol levels as low as 116 mg/dL or even below 70 mg/dL.
So, what are these risk factors?
Your risk of heart disease is higher if you have the following:
- Age: Risk increases as you get older.
- High blood pressure: Having hypertension.
- Family History: If a close family member had heart disease caused by Atherosclerosis at a young age.
- Diabetes: Living with Diabetes Mellitus.
- Low HDL: Having low levels of High-Density Lipoprotein, or “good” cholesterol.
Are Hypercholesterolemia and Hyperlipidemia the same thing?
No, they are slightly different. Hypercholesterolemia is just one specific type under the broader category of Hyperlipidemia. With Hypercholesterolemia, we are specifically focused on high levels of LDL (bad) cholesterol. However, Hyperlipidemia covers elevated levels of any type of fat (lipids) in the blood, not just LDL.
Who is most at risk?
You are more likely to have high LDL cholesterol if you:
- Are over the age of 40.
- Are of South Asian, Filipino, or Vietnamese descent.
- Are a woman who is post-menopausal.
- Are female (in certain circumstances).
How common is Hypercholesterolemia?
It is actually a very common condition. Statistically, one in every twenty people may have it. In the United States, nearly one-third of adults report high LDL levels, and it is frequently seen in Sri Lanka as well.
How does it affect your body?
As we mentioned, Hypercholesterolemia can lead to serious cardiovascular problems, including:
- Stroke
- Coronary artery disease (which leads to heart attacks)
- Peripheral artery disease (issues with the blood vessels supplying your arms and legs)
What are the symptoms?
This is the dangerous part: Most people with Hypercholesterolemia experience no symptoms at all. You may feel perfectly fine, yet your cholesterol levels could be dangerously high inside your body.
However, in rare and severe cases, some people may develop yellow fatty deposits under the skin near the eyelids (Xanthelasma). Similar deposits, called Xanthomas, may appear around tendons or joints. In rare instances, you might see a white ring around the cornea of the eye (Corneal arcus). These physical signs are quite uncommon.
What causes Hypercholesterolemia?
Several factors play a role:
- Genetics: Some people inherit this condition, known as Familial Hypercholesterolemia.
- Diet: Consuming high amounts of saturated and trans fats (e.g., fried foods, processed snacks, certain meats, and bakery products).
- Lack of exercise: Leading a sedentary lifestyle.
- Tobacco use: Smoking or using other tobacco products.
- Other medical conditions:
- Obstructive liver disease
- Diabetes Mellitus
- Hypothyroidism (underactive thyroid)
- Anorexia nervosa
- Chronic kidney failure
- Nephrotic syndrome
- Certain medications: Drugs such as Amiodarone, Rosiglitazone, Cyclosporine, or Hydrochlorothiazide can sometimes raise your cholesterol levels.
How is it diagnosed?
During your annual physical exam, your doctor will typically:
- Review your medical history and family health background.
- Perform a physical examination.
- Order a Lipid Panel blood test, which usually requires fasting for several hours.
What kind of tests are performed?
Once your doctor has confirmed that your hypercholesterolemia isn't caused by underlying conditions, they might suggest genetic testing. If you are specifically diagnosed with Familial Hypercholesterolemia, your doctor may recommend that your family members also undergo genetic screening.
How is it treated?
The primary goal of treating hypercholesterolemia is to lower your LDL cholesterol levels to protect you from the risk of heart disease.
This can be managed in several ways:
- Increased physical activity: Aim for at least 30 minutes of daily activity, such as walking, running, or swimming.
- Maintaining a healthy weight: Reaching and keeping a weight appropriate for your height is vital.
- Reducing saturated fats: Minimize high-fat and oily foods in your diet.
- Managing stress: Find healthy ways to cope with daily stress.
- Cholesterol-lowering medication: Consistently take the medication prescribed by your doctor.
- Avoiding tobacco products:Quitting smoking is essential for your cardiovascular health.
- Controlling blood pressure and blood sugar levels.
- Lipoprotein apheresis: Reserved for severe cases, this procedure uses a specialized machine to filter out harmful lipoproteins from your blood before returning it to your body.
What to eat and what to avoid?
To effectively lower your LDL cholesterol, you can incorporate these dietary changes:
- Limit alcohol consumption: It is best to avoid alcohol as much as possible.
- Focus on fresh produce: Increase your intake of vegetables, leafy greens, fruits, and whole grains.
- Avoid high-saturated fat foods: Limit dairy products like cheese and butter, certain meats (especially red meat), and processed sweets like cakes and biscuits.
Try to fill your plate with colorful vegetables and fruits. Opt for boiled, steamed, or grilled options instead of fried foods. Even when using coconut oil, moderation is key for a heart-healthy diet at Nirogi Lanka.
What medications are used?
Your doctor may prescribe several types of medications to treat hypercholesterolemia:
- Statins: These are the most commonly prescribed medications.
- PCSK9 inhibitors.
- Ezetimibe.
- Bile acid sequestrants.
- Niacin.
- Bempedoic acid.
For those with Familial Hypercholesterolemia, doctors may also prescribe additional specialized treatments.
Are there side effects to treatment?
Like any medication, cholesterol-lowering drugs can cause side effects. However, the health benefits usually far outweigh these risks, and side effects are often manageable.
Common side effects may include:
- Constipation or diarrhea.
- Muscle or joint pain.
- Abdominal discomfort.
- Headaches.
Most importantly, if you experience any side effects, inform your doctor immediately. They can adjust your dosage or switch you to a different medication that suits you better.
How soon can I expect results?
After you start your treatment, your doctor will likely repeat a lipid panel after 8 to 12 weeks to see how your cholesterol levels have responded. Based on these results, they may adjust your medication, switch your prescription, or add a combination therapy to help you reach your goals.
How can I reduce my risk?
You can lower your risk of hypercholesterolemia-related complications by adopting a healthy lifestyle:
- Exercise regularly.
- Maintain a healthy weight.
- Choose a heart-healthy diet.
- Avoid tobacco products.
These habits help protect you not just from high cholesterol, but from many other chronic conditions as well.
What happens if I have hypercholesterolemia?
If you are diagnosed with high LDL cholesterol, it is a lifelong management process. However, don't be discouraged. Once you integrate healthy habits into your daily routine, it becomes a natural part of your life rather than a source of constant worry.
Start with small, sustainable steps. For example, enjoy a meat-free meal once a week, or take a short walk after dinner. When grocery shopping, prioritize items low in saturated and trans fats. Experiment with new vegetables or leafy greens you haven't tried before to keep your diet interesting and nutritious.
What is the long-term outlook?
If left untreated, hypercholesterolemia can lead to atherosclerosis (narrowing of the arteries), which significantly increases your risk of heart attack or stroke.
However, by adopting a healthy lifestyle and taking necessary medications to control your LDL cholesterol, you can significantly reduce your risk. Numerous medical studies show that individuals who effectively manage their cholesterol levels maintain excellent long-term health.
How do I take care of myself?
Because cholesterol management is a lifelong commitment, you must remain consistent with your lifestyle changes and adhere strictly to your prescribed medication.
Keep these in mind:
- Exercise most days of the week.
- Completely avoid all tobacco products.
- Steer clear of foods high in saturated or trans fats.
When should I see my doctor?
Never skip your follow-up appointments. Your doctor needs to monitor:
- If your cholesterol-lowering medication is working effectively.
- If you are experiencing any side effects.
- Your adherence to the recommended treatment plan.
If you experience severe side effects, your doctor can safely adjust your treatment. Regular check-ups are also crucial to ensure your cholesterol levels stay within a safe, healthy range.
What questions should I ask my doctor?
Don't hesitate to ask your doctor these questions during your visit:
- “What types of exercise are best for me to lower my cholesterol?”
- “Can you recommend a program to help me quit smoking?”
- “Can you refer me to a dietitian to help me refine my nutrition plan?”
Having high LDL cholesterol doesn't mean you are alone; it is a very common condition. Your doctor is your best partner in reaching your target levels.
