Whats Behind The New Recommendation

Diets & Healthy Eating : Eating Before a Cholesterol Test

This change has been coming for some time. It is driven by data from a dozen-plus studies that include more than 300,000 people whose cholesterol and other lipids were measured when they hadnt fasted. Their levels predicted cardiovascular risk, as well as, or possibly better than, fasting lipid levels.

Can You Check Cholesterol Without A Blood Test

During a cholesterol test procedure, a blood sample will have to be taken from a vein in your arm.

To do so, a tourniquet is tied around your arm just above the elbow. A needle is then inserted into a vein in your arm near the inside of your elbow. Once the needle is positioned, a small amount of blood is withdrawn and collected in a vial or a syringe.

After the blood is collected, the needle is removed from the vein, and the tourniquet is removed from your arm. A small cotton ball is pressed over the puncture site to stop any bleeding. A Band-Aid may be placed to protect clothing should a small amount of blood leak out of the puncture site.

How long does a cholesterol take?

Having blood tests drawn takes only a few minutes.

Does a cholesterol test hurt?

Blood tests cause a minimal amount of discomfort. Some people do have anxiety about having blood drawn and it may be worse than the pain of the procedure.

Ensuring Good Results For Your Next Test

  • 1Exercise for 30 minutes every day. Whether your cholesterol test results came out high or you’re just trying to maintain your good levels, you can help ensure a positive result at your next lipid test by making some basic lifestyle changes. Perhaps most importantly, physical activity is essential to raising levels of high-density lipoproteins or good cholesterol as it is often called. Aim for at least 30 minutes of aerobic exercise, such as brisk walking, cycling, jogging, or swimming, per day.XTrustworthy SourceMayo ClinicEducational website from one of the world’s leading hospitalsGo to source

    Why Are Cholesterol Tests Used

    A person can have too much cholesterol in their body. Often, people with high cholesterol have no symptoms.

    Cholesterol can combine with other substances in the blood and make a substance called plaque that clogs the arteries.

    The higher a persons cholesterol levels, the more likely they are to have health problems related to high cholesterol, including:

    Cholesterol is a waxy, fat-like substance. Your liver makes all the cholesterol your body needs. But you take in more cholesterol from certain foods, such as those from animals. If you have too much cholesterol in your body, it can build up in the walls of your arteries and eventually harden. This process, called atherosclerosis, actually narrows the arteries, making it harder for blood to travel through the vessels.

    Unfortunately, high cholesterol doesn’t cause symptoms. In later stages of atherosclerosis, though, you may suffer angina — severe chest pain from lack of blood flow to the heart. If an artery gets totally blocked, a heart attack results. A routine blood cholesterol test is a far better way of finding out what your cholesterol level is.

    When Should I Call My Doctor

    If you develop new risk factors for cardiovascular disease, contact your healthcare provider. They may have you undergo a lipid panel or more frequent lipid panel screening.

    A note from Cleveland Clinic

    Seeing an abnormal test result can be stressful. Know that having an abnormal lipid panel result doesnt necessarily mean you need treatment. While cholesterol and triglyceride levels can play a significant role in your overall health, many other factors contribute to your risk for cardiovascular disease. Your healthcare provider will take many factors about your health and history into consideration when determining the next steps. Together you will decide on a plan that works best for you.

    Why Do I Need A Lipid Panel Blood Test

    Cholesterol Testing, To Fast or Not To Fast?

    There are several reasons why you may need a lipid panel blood test. Healthcare providers use lipid panels often for screen and monitoring purposes.

    If you have one or more risk factors for cardiovascular disease, your provider may suggest frequent screening through the use of a lipid panel to try to catch elevated cholesterol levels before you have symptoms. Risk factors for cardiovascular disease include:

    • Being over age 45 if youre a man or you were assigned male at birth and over 50 if youre a women or you were assigned female at birth.
    • Having a high cholesterol result on a previous test.
    • Having diabetes or prediabetes.
    • Having a first-degree relative, such as a parent or sibling, who developed heart disease at an early age .

    Children can also have high cholesterol, so your child may need a lipid panel blood test. Cholesterol levels in children are linked to three factors: heredity, diet and obesity. In most cases, kids with high cholesterol have a parent who also has elevated cholesterol.

    While providers mostly use lipid panels for screening or monitoring cholesterol levels, providers sometimes use them as part of the diagnostic process for certain health conditions that can affect your lipid levels, including:

    If youre experiencing symptoms of any of these conditions, your provider may have you undergo a lipid panel blood test.

    Should You Fast Before A Cholesterol Test

    Several years ago it was announced that there is no benefit in fasting before a cholesterol test. What ever happened as a result of that study, if anything?

    Current cholesterol testing guidelines in the United States stipulate that fasting before a cholesterol test is preferred. But repeated studies have found no clinically significant differences between results from cholesterol tests done on a full stomach and those done after fasting.

    Fasting may provide a more accurate assessment of triglyceride levels, another measure of heart risk. But it doesnt matter if you eat before a cholesterol test if the main goal is to evaluate LDL and HDL cholesterol levels, said Dr. Mary Norine Walsh, the president-elect of the American College of Cardiology.

    One of the barriers to getting cholesterol testing done is that patients arrive at the doctors office not fasting, and then it doesnt get done, Dr. Walsh said. She runs the test even if patients have eaten before an appointment and encourages other doctors to do the same.

    Fasting is just one of those things that gets started and just carries on and on, said Dr. Borge G. Nordestgaard, the first author of the consensus document, which was . He noted that nonfasting triglycerides might be higher after someone eats fat, though not by much, and that the nonfasting sample would be more realistic, providing a better picture of what the average lipid levels in the patient are.

    What You Can Do About Abnormal Lipid Levels

    Lifestyle changes are the first thing to tackle to reduce your chance of heart disease. Your doctor may also recommend that you start taking prescription drugs to help your cholesterol level.

    Lifestyle habits to lower cholesterol

    A cholesterol-lowering diet can bring down bad cholesterol by up to 30%. A diet low in saturated fat and simple carbohydrates and that has no more than 200 miliigrams of cholesterol daily can lower LDL cholesterol. Fiber and plant sterols help, too.

    Keep these dietary tips in mind:

    • Cut saturated fat to less than 7% of your total calories.
    • Avoid trans fat completely. Check the ingredients label for âpartially hydrogenatedâ oils. Those are trans fats. Even if a product says “0 grams trans fat,” it can have a small amount of trans fat , and that adds up.
    • Read food labels. Products that say âlow cholesterolâ or âno cholesterolâ could be too high in saturated fats or sugar.

    Regular aerobic exercise can lower bad cholesterol and raise good cholesterol . If you smoke, quit.

    Lifestyle changes such as diet, exercise, and weight loss are also effective ways to improve your triglyceride levels. Ask your doctor for a sensible diet that will help. If you smoke, get suggestions on ways to help you quit.

    Medications and procedures

    New Guidelines Simplify Cholesterol Tests: No Fasting Needed

    Do I need to fast before a cholesterol test?

    Im supposed to have my cholesterol checked soon. Its a simple test, but Im not looking forward to it since it requires fasting overnight. And that means making a special early-morning trip to my doctors office.

    But new international guidelines say its OK even preferred to skip the overnight fast.

    To learn more about this small but oh-so-useful shift, I talked with cardiologist Dr. Samia Mora. She helped write the new guidelines, which were published this week in the European Heart Journal and summarized in JAMA Internal Medicine. Mora is director of the Center for Lipid Metabolomics at Brigham and Womens Hospital and associate professor of medicine at Harvard Medical School.
