What Is LDL?
But cholesterol isn't all dangerous. Your body needs it to protect its nerves and make healthy cells and hormones.
LDL is a tiny blob made up of an outer rim of lipoprotein with a cholesterol center. Its full name is "low-density lipoprotein."
LDL vs. HDL
Most of the cholesterol in your body is LDL. The rest is high-density lipoprotein (HDL) or “good” cholesterol. HDL takes LDL to your liver, where it’s flushed out of your body. High HDL levels might protect against heart attacks and strokes.
High LDL Cholesterol Diagnosis
A blood test can check your LDL, HDL, and total cholesterol levels. It also measures triglycerides, a type of fat that stores extra energy from your diet. High triglyceride levels can make you more likely to have heart problems.
Lower numbers are better when it comes to LDL cholesterol test results. The general guidelines for adults in the United States are:
- Less than 100 milligrams per deciliter (mg/dL): Optimal
- 100-129 mg/dL: Near or above optimal
- 130-159 mg/dL: Borderline high
- 160-189 mg/dL: High
- 190 mg/dL and above: Very high
If you have a condition like heart disease or diabetes, your doctor might recommend an LDL target of 70 mg/dL or below.
Risks of High LDL Cholesterol
High LDL cholesterol levels can make you more likely to have problems including:
- Coronary artery disease
- Peripheral artery disease
- Heart disease, including chest pain (angina) and heart attack
Guidelines used to focus on lowering "bad" cholesterol to a specific number. Now, you and your doctor will probably work together to come up with a way to lower it by a certain percentage. It's based on how likely it is that you’ll have heart disease or a stroke.
Doctors use a calculator to estimate your odds of those problems in the next 10 years. The calculator considers several things, including:
- Your cholesterol level
- Your age
- Your blood pressure
- Whether you smoke
- Whether you take blood pressure medicine
All of these things affect your chance of having a heart problem. Other risks include:
- A history of heart disease in your family
How to Lower High LDL Cholesterol
- A healthy diet. Try not to eat things that are high in saturated fat, cholesterol, or simple carbs such as sugar and white flour. Eat more fiber and plant sterols such as margarine or nuts.
- Regular exercise. The kind that gets your heart pumping is best.
- Weight loss. Losing even 5 to 10 pounds can improve your cholesterol levels.
- Quitting tobacco. If you have a hard time giving up smoking, your doctor can help you find the program that’s best for you.
- Medication. Some drugs, like statins, help keep your body from making cholesterol. Another, ezetimibe (Zetia), lowers the amount of cholesterol your body gets from food you eat. If you can’t take statins or have a severe form of high cholesterol, you might get shots of PCSK9 inhibitors. These meds help your liver remove more LDL from your blood.
