What are blood lipids?
- Lipids are fat-like substances found in your blood and body tissues.
- Your body needs small amounts of lipids to work normally.
How are my blood lipids measured?
- A blood test called a complete lipid profile is done.
- It is recommended that this test be done after an overnight fast.
What happens if my lipids are too high?
An excess amount of blood lipids can cause fat deposits in your artery walls, increasing your risk for heart disease.
Are there different kinds of lipids?
Cholesterol is the main lipid. It is made up of different parts such as:
- LDL cholesterol, or “bad” cholesterol, is the main lipid that causes damaging buildup and blockage in your arteries.
- HDL cholesterol is actually a “good” type of cholesterol that helps to prevent cholesterol from building up in your arteries.
- Triglyceride is another lipid that may increase your risk for heart disease.
What are healthy lipid levels?
- Your total cholesterol should be less than 200.
- Your HDL cholesterol should be 40 or higher.
- Your LDL cholesterol should be less than 100. Ask your doctor.
- Your triglyceride level should be less than 150.
If my lipids are not at the right levels, what can be done to improve them?
- Your doctor may recommend that you follow a diet low in saturated fats and cholesterol.
- You may also need to increase your activity level.
- In some cases, you may also need to take a medication to help lower your lipid levels.

A lipid profile is a blood test that measures the amount of cholesterol and fats called triglycerides in the
blood. These measurements give the doctor a quick snapshot of what's going on in your blood. Cholesterol and
triglycerides in the blood can clog arteries, making you more likely to develop heart disease. Thus, these tests can help predict your risk of
heart disease and allow you to make early lifestyle changes that lower cholesterol and triglycerides. A report typically contains the following items, in this order: Some reports also include: Total Blood (Serum) Cholesterol In general, doctors recommend that you try to keep this number under 200 mg/dL. Levels over 200 mg/dL -- depending on the breakdown of
LDL versus HDL -- may mean you are at higher risk for heart disease. Having a total cholesterol level over 240 mg/dL may double the risk of heart disease. Low-density lipoprotein (LDL) Low-density lipoprotein is
bad cholesterol. Think of the "L" in LDL as "lousy." High LDL levels increase the risk of heart disease. Your actual LDL goal depends on whether or not you have existing risk factors for heart disease, such as diabetes or high blood pressure. But in general, LDL results
are as follows:How to Read Your Lipid Panel
Based on your risk for heart disease, your doctor will discuss with you strategies for lowering your LDL by a certain percentage. Those strategies will include lifestyle changes -- including dietary changes and exercise -- as well as the use of cholesterol lowering
medication. Together, you and your doctor will decide on the appropriate strategies for your particular situation. High-Density Lipoprotein (HDL) High-density lipoprotein (HDL) is good cholesterol. Think of the "H" in HDL as "healthy" to remember this cholesterol type as the good kind.
HDL helps carry bad cholesterol out of the bloodstream and arteries. It plays a very important role in preventing clogged arteries. So, the higher the HDL number, the better.
In general, HDL levels of 60 mg/dL or higher are considered to be good. Likewise, levels below 40 mg/dL are considered a risk factor for heart disease. But it's important to discuss with your doctor what level is best in your particular case.
Certain medications, including steroids, blood pressure drugs known as beta blockers, and some ‘water pills’ can interfere with HDL levels. Make sure your doctor always knows about all the medications you are taking.
Triglycerides
Triglycerides are a type of blood fat that has been linked to heart disease and diabetes. If you have high triglycerides, your total cholesterol and LDL levels may be high, as well.
- Normal: less than 150 mg/dL
- Borderline-High: 150-199 mg/dL
- High: 200-499 mg/dL
- Very High: 500 mg/dL
Lifestyle plays a large role in your triglyceride level. Smoking, excessive drinking, uncontrolled diabetes, and medications such as estrogen, steroids, and some acne treatments can contribute to high triglyceride levels. However, in some cases, genes or an underlying disease can be the cause.
Total Cholesterol to HDL Ratio
This number is not always listed on a cholesterol report. Some doctors use this instead of the total cholesterol level to help decide on an approach to lowering cholesterol. However, the American Heart Association recommends that focussing on actual values rather than ratios is more useful in determining treatment.
Very Low-Density Lipoprotein (VLDL)
This is a type of bad cholesterol that contains the
highest amount of triglycerides. The higher your VLDL level, the more likely you are to have a heart attack or stroke. The VLDL level is not always included in cholesterol reports. There is no simple or direct way to measure VLDL. Most labs estimate it by dividing the triglyceride level by 5. However, this is not valid if the
triglyceride level is over 400. Normal VLDL levels range from 5 - 40 mg/dL. Keep in mind your cholesterol report offers a general guideline only. What's normal for you may not be OK for someone else. Your doctor will look at all your cholesterol numbers together
with your other risk factors to develop a specific strategy for you. Your goal depends on your age, family history of heart disease, and whether or not you have other risk factors for heart disease, such as diabetes, high blood pressure, and weight problems. Results may even vary depending on the lab a doctor uses. Always ask your doctor
to help you interpret test results. Adults aged 20 and older should have their cholesterol and triglyceride levels checked once every five years. However, your doctor may suggest doing this more often if you have certain risk factors such as diabetes, high blood pressure, obesity, or a family history of heart disease.What's Your Goal?
