High Cholesterol (Hypercholesterolemia) Care in Florence, AL
Hypercholesterolemia is the medical term for high cholesterol, a condition where fatty substances build up in your blood at levels that can contribute to narrowed arteries over time. Cholesterol itself isn't inherently harmful. In fact, your body needs a certain amount of it to build cells and produce important hormones. Your liver actually makes all the cholesterol your body needs on its own, though cholesterol from food can add to that supply.
Like many cardiovascular risk factors, high cholesterol typically causes no symptoms, so it's usually discovered through routine bloodwork rather than because someone feels unwell. Dr. Naidu looks beyond a single number, considering your LDL, HDL, triglycerides, family history, and other risk factors together to understand what your results actually mean for your heart.
Whether your numbers came back high, you have a family history of early heart disease, or you simply haven't been checked in a while, request an appointment and let's get you scheduled.
Understanding Cholesterol
What Causes High Cholesterol?
High cholesterol can result from a combination of diet, physical activity level, body weight, age, and genetics. Diets high in saturated and trans fats tend to raise LDL cholesterol, since these fats prompt the liver to produce more cholesterol than the body actually needs. On the other hand, diets rich in fruits, vegetables, whole grains, and healthy fats tend to support more balanced cholesterol levels.
A sedentary lifestyle is another contributing factor, since regular physical activity tends to raise protective HDL cholesterol while helping lower LDL and triglycerides. Body weight plays a role as well, since carrying excess weight, particularly around the midsection, is linked to higher LDL and lower HDL levels.
Age and biological sex also influence cholesterol patterns. Levels tend to rise gradually as people get older, and hormonal shifts, such as those that occur around menopause, can shift cholesterol balance as well. Genetics can play an especially significant role for some people. In familial hypercholesterolemia, an inherited tendency toward high LDL cholesterol exists regardless of diet or activity level, meaning even people with generally healthy habits can have significantly elevated numbers. This is one of several reasons routine screening matters for everyone, not just people who appear to have obvious risk factors.
What Is the Difference Between LDL and HDL Cholesterol?
LDL cholesterol is often called "bad" cholesterol because of its tendency to deposit along artery walls when levels run high. Think of LDL as the primary carrier that transports cholesterol from the liver to the rest of the body. When there's more LDL circulating than the body needs, the excess can settle into artery walls and contribute to plaque formation, gradually narrowing the space available for blood to flow through.
HDL cholesterol works in the opposite direction. It acts something like a cleanup crew, gathering excess cholesterol from the bloodstream and arteries and carrying it back to the liver, where it can be processed and removed from the body. Because of this protective role, higher HDL levels are generally considered beneficial for cardiovascular health.
Triglycerides are a related but distinct measurement. They aren't technically cholesterol, but rather another type of fat in the blood that represents stored energy. High triglyceride levels, especially when combined with high LDL or low HDL, can further increase cardiovascular risk. When cholesterol is checked, all of these numbers, LDL, HDL, and triglycerides, are considered together as a complete picture rather than looked at individually, since the balance between them tells a more complete story than any single number alone.
How Is High Cholesterol Diagnosed?
Hypercholesterolemia is diagnosed through a simple blood test called a lipid panel, which measures total cholesterol along with LDL, HDL, and triglycerides. This test usually requires fasting beforehand, since eating can temporarily affect some of the numbers, particularly triglycerides.
Because high cholesterol causes no symptoms, routine screening bloodwork is really the only reliable way to catch it before it contributes to bigger problems. Most healthy adults are advised to have their cholesterol checked periodically starting in early adulthood, even without any known risk factors, since levels can be elevated at any age.
The frequency of testing often depends on individual risk factors, including family history, previous results, and other health conditions like diabetes. People with a strong family history of high cholesterol or early heart disease may need more frequent monitoring than the general population. Once a diagnosis is made, ongoing testing also helps track whether cholesterol levels are moving in a healthier direction over time, giving both patients and healthcare providers useful feedback on how well current habits and any other management strategies are working.
What Health Problems Can High Cholesterol Lead To?
Over time, untreated high cholesterol contributes to a gradual buildup of plaque inside the arteries, a process called atherosclerosis. As this buildup progresses, it narrows the space available for blood to flow through, restricting circulation to whatever tissue or organ that artery supplies.
When this process affects the arteries supplying the heart, it can contribute to reduced blood flow to the heart muscle itself, which can eventually lead to chest discomfort or more serious cardiac events. The same underlying process can affect arteries throughout the body, including those supplying the legs and brain, meaning the impact of high cholesterol isn't limited to any single organ.
Because this progression happens gradually, often over many years, the risk builds quietly in the background long before any noticeable problems appear. This is part of why ongoing management matters even when someone feels completely healthy and shows no outward signs of trouble. The good news is that this process can be meaningfully slowed, and sometimes even partially improved, which is why catching and monitoring elevated cholesterol early tends to lead to better long-term outcomes than discovering it after complications have already developed.
How Can I Support Healthy Cholesterol Levels Day to Day?
Diet is one of the most direct ways to influence cholesterol levels on a daily basis. Reducing saturated and trans fats, found in items like fatty meats, full-fat dairy, and many fried or packaged foods, can help lower LDL cholesterol over time. Meanwhile, increasing fiber-rich foods like fruits, vegetables, and whole grains supports healthier overall levels.
Regular physical activity is another meaningful habit, since it tends to raise protective HDL cholesterol while also helping lower LDL and triglycerides. Even moderate activity, like brisk walking several times a week, can make a measurable difference over time for many people.
Maintaining a healthy weight supports better cholesterol balance as well, since carrying excess weight is linked to higher LDL and lower HDL levels. Avoiding tobacco use is equally important, since smoking specifically lowers protective HDL cholesterol while damaging blood vessel walls, making it easier for cholesterol to deposit and form plaque.
Routine screening remains an essential habit alongside these lifestyle choices, since cholesterol changes happen gradually and can't be felt day to day. Checking in periodically with bloodwork helps confirm whether these daily habits are actually translating into healthier numbers, and allows adjustments to be made before small imbalances become bigger concerns.
Frequently Asked Questions
Does high cholesterol cause noticeable symptoms?
Typically, no. High cholesterol usually causes no aches, fatigue, or physical signs at all, so someone can feel completely healthy while elevated levels quietly contribute to changes in their arteries. Unfortunately, the first noticeable sign of long-term untreated high cholesterol is sometimes a serious cardiovascular event, which is why routine screening is so much safer than waiting for symptoms.
Do I only need to worry about cholesterol if I'm overweight?
No. Excess weight is a contributing factor, but genetics plays a substantial role for many people. In familial hypercholesterolemia, LDL runs high regardless of diet or activity level, so even people at a healthy weight with active lifestyles can have elevated numbers. Plaque buildup in the arteries can also begin much earlier in life than most people realize.
When should I have my cholesterol checked?
Guidelines generally recommend screening starting in early adulthood, then every several years for most average-risk adults. More frequent testing makes sense if you have a family history of high cholesterol or early heart disease, diabetes, other cardiovascular conditions, or previous borderline results. If you can't remember your last check, or you've never been tested, it's a simple thing to bring up at your next appointment.
