What cholesterol is and what cholesterol blood tests show

Your doctor will make a treatment recommendation based on your level of heart disease risk. Guidelines do not use a single cholesterol level to determine treatment options.

  • If you already have coronary heart disease with symptoms such as chest pain or a previous heart attack, taking medication to reduce your low density lipoprotein cholesterol is very beneficial and possibly life-saving.
  • If you have been hospitalized due to heart attack or stroke, you will start treatment before you leave the hospital. The latest 2018 cholesterol guidelines recommend using a high-intensity statin , such as higher doses of;rosuvastatin or atorvastatin to get cholesterol levels below 70 mg/dL. You will be encouraged to follow a heart-healthy diet, exercise, lose weight and stop smoking, if needed.
  • If you do not have a diagnosis of heart disease but your cholesterol levels are high, your doctor will look at your other risk factors, and may determine your 10-year risk of cardiac disease. Usually, lifestyle changes like a healthy diet and exercise are implemented for the first 6 to 12 months. Diet and exercise can drop cholesterol levels by roughly 10 percent.

Who Is It Best For

Anyone with a heart valve problem, murmur, or history of heart attack. Lower percentages of blood pumped by the left ventricle may indicate dysfunction and increased risk of congestive heart failure.

A blood test measures levels of this abrasive amino acid, which irritates the lining of arteries, opening them up to infiltration by LDL and leading to plaque and blood clotting.

Facts You Should Know About Cholesterol Tests

  • Cholesterol is a naturally occurring substance in the body that is an important part of normal body function.
  • Cholesterol has two main types: HDL, or good cholesterol, that protects against heart disease, stroke and peripheral vascular disease; and LD, or bad, cholesterol, which increases the risk of these conditions.
  • Cholesterol tests measure total cholesterol as well as HDL and LDL levels in the blood. Triglycerides, another type of fat present in the bloodstream, may also be measured.
  • Cholesterol tests are usually ordered and blood drawn in a doctor’s office. There are also home test kits available. It is important to be fasting for the tests to be accurate. Typically, a fasting test is performed first thing in the morning before the individual has eaten anything for the day. Fasting typically requires 12 hours without food. Water, plain tea or coffee are permitted, and hydration is required. No other liquids are acceptable during the fasting period. Patients cannot add sugar, artificial sweeteners, cream, or milk to drinks.
  • If you take OTC, prescription, or herbal supplements discuss these with your doctor prior to the test.
  • Cholesterol test results should be discussed with the health-care professional to determine if treatment of high cholesterol is necessary to decrease the risk of heart disease and stroke.

What Is A Lipid Panel

A lipid panel measures levels of different kinds of fats in the blood.;

  • Total cholesterol, which is the amount of the different types of cholesterol added together. Cholesterol is a fatty substance that the body needs some of. But too much cholesterol can cause problems.
  • High-density lipoprotein cholesterol, often called “good” cholesterol. HDL helps the body get rid of extra cholesterol.
  • Low-density lipoprotein cholesterol, often called “bad” cholesterol. LDL that builds up in the bloodstream can clog blood vessels and increase the risk of heart disease.
  • Triglycerides, which store energy until the body needs it. If the body holds on to too many triglycerides, blood vessels can get clogged and cause health problems.

Can You Lower Triglycerides Naturally Without Drugs

Cholesterol tests are blood tests that measure the amount of cholesterol in the body. The health care professional may order only a cholesterol test with results showing:

  • The total cholesterol,
  • HDL, and

    Can Test Results Be Wrong

    In some cases, cholesterol test results can be wrong. For example, a study published in the Journal of the American College of Cardiology found that one common method for calculating LDL cholesterol levels often produces inaccurate results.

    Improper fasting, medications, human error, and a variety of other factors can cause your test to produce false-negative or false-positive results. Testing both your HDL and LDL levels typically produces more accurate results than checking your LDL alone.

    High cholesterol can be treated with lifestyle changes and medication. Lowering high levels of LDL in your blood can help you avoid problems with your heart and blood vessels.

    To help lower your cholesterol levels:

    • Quit smoking tobacco and limit your alcohol consumption.
    • Avoid high-fat and high-sodium foods, while maintaining a well-balanced diet. Eat a wide variety of vegetables, fruits, whole-grain products, low-fat dairy products, and lean sources of protein.
    • Exercise regularly. Try to do 150 minutes of moderate intensity aerobic activity per week, as well as two sessions of muscle strengthening activities.

    Your doctor may put you on a therapeutic lifestyle changes or TLC diet. Under this meal plan, only 7 percent of your daily calories should come from saturated fat. It also requires you to get less than 200 mg of cholesterol from your food each day.

    Some foods help your digestive tract absorb less cholesterol. For example, your doctor may encourage you to eat more:
