High Cholesterol Explained: LDL, HDL, Healthy Numbers and the New 2026 Targets
Written by Cherlie Joseph, MSN, FNP-BC · Medically reviewed by Naurah Gaspard, DNP, FNP-C, FNP-BC · Updated November 2026
High cholesterol usually means too much LDL ("bad") cholesterol in your blood, which slowly builds plaque in your arteries and raises your risk of heart attack and stroke. It causes no symptoms, so a simple blood test called a lipid panel is the only way to find it. Under the 2026 ACC/AHA guideline, most adults are aiming for an LDL under 100 mg/dL, and people at higher risk aim for under 70 or even under 55.

What cholesterol is and why LDL matters most
Cholesterol is a waxy fat your body needs to build cells and hormones. Your liver makes most of it, and the rest comes from food. It travels through your blood in particles called lipoproteins:
- LDL (low-density lipoprotein) carries cholesterol into artery walls. Over years, extra LDL becomes plaque that narrows arteries. This is the main number your provider treats.
- HDL (high-density lipoprotein) helps carry cholesterol back to the liver. Higher is generally better, but medicines that raise HDL have not been shown to prevent heart attacks, so it is not a treatment target.
- Triglycerides are a different blood fat that rises with sugar, refined carbs, alcohol and insulin resistance.
- Non-HDL cholesterol is total cholesterol minus HDL. It captures every particle that can build plaque and is now used alongside LDL.
High cholesterol does not cause chest pain, fatigue or any warning signs on its own. Some people with very high inherited levels have yellowish deposits on the eyelids or tendons, but most people feel completely fine.
Healthy cholesterol numbers and the 2026 LDL goals
In March 2026, the American College of Cardiology, American Heart Association and nine other groups released a new dyslipidemia guideline. The big change: it brings back specific LDL goals instead of just "take a statin." Your goal depends on your risk, not just your number.
| Your situation | LDL goal |
|---|---|
| No heart disease, borderline or intermediate 10-year risk | Under 100 mg/dL |
| No heart disease, high risk (10% or more over 10 years) | Under 70 mg/dL |
| Prior heart attack, stroke or stent (clinical ASCVD) | Under 70 mg/dL |
| ASCVD at very high risk | Under 55 mg/dL |
The guideline also switches to the AHA PREVENT calculator to estimate 10-year and 30-year risk for adults 30 to 79. It uses your age, blood pressure, cholesterol, diabetes status, smoking and kidney function. Adults 40 and older with diabetes, chronic kidney disease (stage 3 or worse) or HIV are advised to start cholesterol-lowering treatment. An LDL of 190 mg/dL or higher often points to an inherited condition called familial hypercholesterolemia and is treated regardless of the calculator.

- Lipid panel: total cholesterol, LDL, HDL, triglycerides and non-HDL. Fasting is usually not required unless your triglycerides were high before.
- Lipoprotein(a), or Lp(a): the 2026 guideline recommends checking it once in every adult. It is mostly genetic, so one test is usually enough, and a high result raises your risk even when LDL looks fine.
- ApoB: counts plaque-forming particles. It can help if you have diabetes, high triglycerides or metabolic syndrome and already meet your LDL goal.
- Coronary artery calcium (CAC) scan: a quick CT scan that can help when the decision to start a statin is unclear.
Your provider may also check A1c, a metabolic panel and thyroid function, because diabetes, kidney disease and an underactive thyroid can all raise cholesterol.
How to lower cholesterol: lifestyle and medicines
Lifestyle comes first and keeps helping even after medicine starts. The changes with the best evidence are swapping saturated fat (fatty red meat, butter, fried foods) for unsaturated fats like olive oil, nuts and fish; eating more soluble fiber from oats, beans, lentils and fruit; staying active most days; not smoking; and losing weight if you carry extra.
Statins such as atorvastatin and rosuvastatin are first-line medicines. They lower LDL by roughly 30% to 50% or more depending on the dose, and they have strong evidence for preventing heart attacks and strokes. Most are inexpensive generics.
If a statin plus lifestyle does not reach your goal, or you cannot tolerate one, add-on options include ezetimibe, bempedoic acid (Nexletol) and PCSK9 inhibitor injections such as evolocumab (Repatha) and alirocumab (Praluent). Brand prices and insurance coverage change often, so check the manufacturer's website for current savings programs.
Muscle aches are the side effect people worry about most. Many aches turn out not to be caused by the statin, and switching drugs or adjusting the dose often solves the problem. Do not stop on your own; talk with your provider first.
Getting your cholesterol care online in Florida
At OurTopClinic, a nurse practitioner licensed in your state can review your recent lipid panel, help you understand your risk, order labs at a nearby Quest or Labcorp, and renew non-controlled cholesterol medicines like statins and ezetimibe when it is safe to do so. A refill is never guaranteed; your provider decides based on your history and labs. Most people on a stable dose recheck a lipid panel 4 to 12 weeks after starting or changing a medicine, then every 3 to 12 months as needed.
Get in-person care or call 911 if you have:
- Chest pain, pressure or squeezing, especially with sweating, nausea or shortness of breath
- Sudden weakness or numbness on one side, a drooping face or trouble speaking
- Severe muscle pain or weakness with dark, cola-colored urine while taking a statin
- Pain in the calf or leg that comes on suddenly with a cold, pale foot
Frequently asked questions
What is a normal cholesterol level?
For most adults, an LDL under 100 mg/dL, HDL of 40 mg/dL or higher for men and 50 mg/dL or higher for women, and triglycerides under 150 mg/dL are considered healthy. Your personal LDL goal may be lower depending on your heart risk.
Can I lower my cholesterol without medication?
Often, yes, especially if your LDL is only modestly high and your overall risk is low. Diet changes, more fiber, exercise and weight loss can lower LDL meaningfully. People at high risk or with very high LDL usually need medicine as well.
How often should I get my cholesterol checked?
Healthy adults are generally checked every 4 to 6 years starting around age 20. If you have high cholesterol, diabetes, or take a cholesterol medicine, your provider will check it more often.
