High Cholesterol: What It Means and What to Do About It

Your cholesterol came back high. The lab report has numbers you don't fully understand, your provider circled something and said "we should keep an eye on this," and now you're trying to figure out how worried you should actually be. That's the situation most people are in when they start looking into cholesterol for the first time.

High cholesterol affects nearly 94 million U.S. adults age 20 and older, according to the CDC. Unlike conditions that make you feel sick, elevated cholesterol works quietly. You won't feel it building up in your arteries. By the time it causes a noticeable problem, the problem is usually serious: a heart attack, a stroke, or peripheral artery disease.

Key Facts

• Prevalence: About 38% of U.S. adults have total cholesterol above 200 mg/dL (CDC, 2023)
• Typical onset: Cholesterol levels tend to rise after age 20 and accelerate after 40, especially in women post-menopause
• Commonly confused with: Normal cholesterol variation, temporary dietary spikes
• When to see a provider: If your LDL is above 130 mg/dL or your total cholesterol is above 200 mg/dL

Symptoms of High Cholesterol

High cholesterol has no symptoms. None. You can't feel it. There's no pain, no fatigue, no signal that tells you plaque is building in your arteries. That's what makes it dangerous, and that's why regular screening matters.

The only way to know your cholesterol levels is through a blood test called a lipid panel. This test measures four things:

• Total cholesterol: A combined measure of all cholesterol in your blood
• LDL ("bad" cholesterol): The type that builds up in artery walls
• HDL ("good" cholesterol): The type that helps remove LDL from your arteries
• Triglycerides: A type of fat in your blood that contributes to artery hardening

Some people first discover they have high cholesterol when they experience a cardiovascular event. That's the worst way to find out. Xanthomas, yellowish deposits of cholesterol under the skin around the eyes or on tendons, can sometimes appear in people with very high cholesterol or familial hypercholesterolemia, but these are uncommon.

The USPSTF recommends cholesterol screening for all adults starting at age 20, with repeat testing every 4-6 years if levels are normal. More frequent testing is recommended if you have risk factors.

What Causes High Cholesterol

Cholesterol is a waxy substance your liver produces naturally. Your body needs it for cell membranes, hormone production, and digestion. Problems arise when there's too much LDL in your blood, either because your body produces too much or because your diet adds to it and your body can't clear the excess.

Modifiable factors:

• Diet high in saturated fat, trans fat, and dietary cholesterol (red meat, full-fat dairy, fried foods, processed baked goods)
• Lack of physical activity, which lowers HDL
• Excess weight, which raises LDL and triglycerides
• Smoking, which damages blood vessels and lowers HDL
• Excessive alcohol intake, which raises triglycerides

Non-modifiable factors:

• Genetics. Familial hypercholesterolemia is an inherited condition that causes very high LDL levels from birth. It affects about 1 in 250 people.
• Age. Cholesterol levels naturally rise with age.
• Sex. Before menopause, women tend to have higher HDL levels. After menopause, LDL often rises.

Contributing medical conditions:

• Type 2 diabetes (worsens lipid profiles)
• Hypertension (compounds cardiovascular risk when combined with high cholesterol)
• Hypothyroidism (underactive thyroid slows cholesterol clearance)
• Kidney disease
• Liver disease

How High Cholesterol Is Diagnosed

Diagnosis is based on a lipid panel, typically drawn after a 9-12 hour fast (though non-fasting panels are increasingly accepted for initial screening).

Target ranges for most adults:

• Total cholesterol: Below 200 mg/dL (desirable)
• LDL cholesterol: Below 100 mg/dL (optimal); below 70 mg/dL if you have heart disease or diabetes
• HDL cholesterol: Above 40 mg/dL for men, above 50 mg/dL for women; above 60 mg/dL is protective
• Triglycerides: Below 150 mg/dL

Your provider won't just look at cholesterol numbers in isolation. They'll assess your 10-year cardiovascular risk using a tool like the Pooled Cohort Equations (PCE), which factors in your age, sex, race, blood pressure, cholesterol levels, diabetes status, and smoking status. This risk score guides treatment decisions.

If your LDL is borderline, your provider may repeat the test in 3-6 months to confirm, particularly if you've recently changed your diet or started exercising.

Treatment Options for High Cholesterol

Lifestyle changes (first step for everyone):

• Switch to a heart-healthy diet. The DASH and Mediterranean diets both improve lipid profiles. Prioritize fruits, vegetables, whole grains, fish, nuts, and olive oil. Reduce saturated fat to less than 7% of total calories.
• Exercise. At least 150 minutes per week of moderate-intensity aerobic activity can raise HDL by 5-10% and lower LDL and triglycerides.
• Lose weight. Even a 5-10% reduction in body weight improves cholesterol numbers.
• Quit smoking. Quitting raises HDL within weeks.
• Limit alcohol. One drink per day for women, two for men.

Medication (when lifestyle changes aren't sufficient or risk is high):

• Statins are the first-line medication for most people with elevated LDL. They reduce LDL by 30-50% and have decades of evidence supporting cardiovascular benefit. Common drug classes include high-intensity and moderate-intensity statins.
• Ezetimibe blocks cholesterol absorption in the intestine and is often added when a statin alone doesn't reach target LDL.
• PCSK9 inhibitors are injectable medications for people with very high LDL who don't respond adequately to statins and ezetimibe. They can reduce LDL by an additional 50-60%.
• Fibrates and omega-3 fatty acid prescriptions target high triglycerides specifically.
• Bile acid sequestrants are an older class that binds cholesterol in the gut. Used less frequently now but still an option.

Your provider will recommend treatment based on your overall risk profile, not just your LDL number.

When to See a Provider

Get screened if you're over 20 and haven't had a lipid panel in more than 5 years. Get screened sooner if you have a family history of early heart disease (before age 55 in men, 65 in women), diabetes, high blood pressure, or if you smoke.

If you're already on cholesterol medication and your numbers haven't improved after 6-12 weeks, follow up. The medication may need adjustment, or there may be an absorption or adherence issue worth discussing.

Seek immediate medical attention if you experience chest pain, sudden shortness of breath, weakness on one side of your body, or sudden difficulty speaking. These could be signs of a heart attack or stroke.

How Ascend Treats High Cholesterol

Cholesterol management at Ascend Mind and Body is handled through our primary care team, led by Dr. Jason Saylor, DO. We see patients for initial screening, ongoing management, and medication adjustments at our Wesley Chapel and Tampa offices.

We look at cholesterol as part of your total cardiovascular risk, not as a standalone number. If you're also managing hypertension or type 2 diabetes, we build a coordinated plan instead of treating each condition in a silo.

Your first visit includes a thorough review of your lipid panel history, any medications you've tried, your diet and exercise patterns, and your family history. We set realistic targets based on your individual risk, not on a generic chart.

Currently accepting Aetna in-network, with BCBS, Humana, Medicare, and additional carriers in the credentialing process. See our new patients page to get started.
