What Is Hdl Cholesterol
Now that you understand what LDL cholesterol is and how it impacts your health, it is time to learn about HDL cholesterol. What is HDL cholesterol? It is an abbreviation for the term high-density lipoproteins.
Is HDL good or bad? HDL is considered to be good cholesterol. High-density lipoproteins transport cholesterol to the liver where it is used to create hormones and vitamins. Any excess cholesterol is then removed from the body to reduce the risk of a variety of health conditions.
When excess cholesterol is moved from the body, the risk of illness and disease is minimized. Your kidney health will improve. Your risk of a heart attack or stroke will also be decreased. Knowing how to lower your LDL levels and how to increase HDL levels can improve your health.
When Should You Contact Your Healthcare Provider About Your Cholesterol Levels
In truth, your healthcare provider will probably talk to you about your numbers first. As always, contact your provider if you have any new or worsening pain or other uncomfortable feelings. Make sure you know what medications you take and what they are expected to do. Call the provider if you have a reaction to the medicine.
Before you go to the office, and after you have had a cholesterol test, it helps to have a list of questions prepared about your test results and any proposed treatment.
A note from Cleveland Clinic
When considering cholesterol numbers, its important to remember that you really have the ability to make those numbers go in your favor. What you choose to eat, how much you are able to move and how you deal with lifes ups and downs are things that you can influence.

Cholesterol is both good and bad. At normal levels, it is an essential substance for the body. However, if concentrations in the blood get too high, it becomes a silent danger that puts people at risk of heart attack.
There are two types of cholesterol:
- low-density lipoproteins , or bad cholesterol
- high-density lipoproteins , or good cholesterol
What Are The Different Types Of Cholesterol
There are two types: high-density lipoprotein and low-density lipoprotein . As a general rule, HDL is considered good cholesterol, while LDL is considered bad. This is because HDL carries cholesterol to your liver, where it can be removed from your bloodstream before it builds up in your arteries. LDL, on the other hand, takes cholesterol directly to your arteries. This can result in atherosclerosis, a plaque buildup that can even cause heart attack and stroke.
Triglycerides make up the third component of cholesterol and act as unused calories that are stored as fat in the blood. Eating more calories than you burn can cause triglycerides to build up in the bloodstream, increasing your risk for heart attacks.

How To Lower Cholesterol: Low
Low-carbohydrate diets may help improve HDL cholesterol levels. The National Institutes of Health conducted a study that found while both low-fat and low-carb dieters lost weight over the two-year study period, low-carb dieters also improved their HDL cholesterol levels. The problem with low-carb diets is that they may be difficult to adhere to. Consult your doctor about the best healthy eating plan to manage your cholesterol.
Effects Of High Cholesterol
The higher the level of LDL cholesterol in your blood, the greater your chance is of getting coronary heart disease. The higher the level of HDL cholesterol in your blood, the lower your chance is of getting heart disease.
Coronary heart disease is a condition in which plaque builds up inside the coronary arteries. This limits the flow of oxygen-rich blood to your heart muscle.
Eventually, an area of plaque can rupture . This causes a blood clot to form on the surface of the plaque. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery.
If the flow of oxygen-rich blood to your heart muscle is reduced or blocked, angina or a heart attack may occur.

How To Lower Ldl Cholesterol
Lifestyle and diet changes are the main ways to prevent or lower high LDL. A trial of eating a low-fat diet, regular aerobic activity, maintaining a healthy weight, and smaller waist circumference is an appropriate first step. It is best to set a timeline to achieve your goals with your doctor. In some cases, if those lifestyle changes are not enough, your physician may suggest a cholesterol lowering medication, such as a statin. If you are considering over-the-counter herbal or ayurvedic medications for cholesterol, please discuss those with your physician first as well.
Rarely, very high LDL is genetic and passed down in families. This is called familial hypercholesterolemia and is caused by a genetic mutation that decreases the livers ability to clear excess cholesterol. This condition can lead to very high LDL levels, and heart attack or stroke at a young age in multiple generations. Those individuals may require special medical treatment for prevention and treatment of atherosclerotic cardiovascular disease.
Remember, knowledge is the first step. If you dont know your cholesterol levels, get tested. That will give you and your physician a starting point for lifestyle changes and medications if needed. In the meantime, adopt a heart-healthy lifestyle, and do it with friends and family no matter their ages. Theres no time like the present to prevent heart disease.

Know Your Cholesterol Levels
Before we discuss how to lower your LDL levels, you must first learn what your total cholesterol is. The average normal cholesterol level for adults is under 200. According to the CDC, approximately ninety-four million American adults have high than normal total cholesterol levels.
If you have higher than normal cholesterol readings, you are at an increased risk of developing health problems, which is why it is important to understand the importance of knowing your LDL vs HDL readings. Knowing your cholesterol readings is the first step toward a reduced risk of disease and even death. In addition to this, you should know your LDL HDL ratio as it can be used as an indicator of your overall health.

How Often Should You Test Your Cholesterol
The U.S. Preventive Services Task Force and the American Heart Association recommend that men ages 45 to 65 and women ages 55 to 65 get tested every one to two years.
The test for non-HDL cholesterol isn’t usually part of screening for your total cholesterol, but your healthcare provider may ask you to check these levels if you have high blood pressure, diabetes, or other risk factors for heart disease.
Getting Help For Your Child
If you are worried about your child’s weight, consider consulting with a registered dietitian or expressing your concerns with your pediatrician.
Children can benefit from getting involved in meal planning, shopping, and cooking, reducing intake of sweetened beverages, and learning how to eat more fruits and vegetables. Being a good role model and getting the entire family on board is also important for making changes and providing your child with confidence.

Whats Your Cholesterol Level Anyway
A standard lipid blood test usually measures the concentration of total cholesterol, HDL cholesterol, and triglycerides levels. The LDL-cholesterol level is typically estimated from these numbers using a well-established formula that has been more recently revised and improved by researchers at Johns Hopkins.
So what are your target numbers? According to Michos, an ideal LDL cholesterol level should be less than 70 mg/dl, and a womans HDL cholesterol level ideally should be close to 50 mg/dl. Triglycerides should be less than 150 mg/dl. As Michos notes, total cholesterol levels well below 200 mg/dl are best.
Why Is Cholesterol Important To Our Bodies
Every cell in the body needs cholesterol, which helps the cell membranes form the layers. These layers protect the contents of the cell by acting as the gatekeeper to what things can enter or leave the cell. It is made by the liver and is also used by the liver to make bile, which helps you digest foods. Cholesterol is also needed to make certain hormones and to produce vitamin D. Your liver makes enough cholesterol to meet your bodys needs for these important functions.

Why Cholesterol Matters For Women
Ah, cholesterol and triglycerides. We hear about them all the time. Even foods that might seem good for you on the surface, like fruit-filled yogurt or bran muffins, can contribute to abnormal levels if they contain too much saturated fat or refined sugar, says Erin Michos, M.D., associate director of preventive cardiology at the Ciccarone Center for the Prevention of Heart Disease.
Whats more, many women are at risk for high cholesterol and dont realize it. Approximately 45 percent of women over the age of 20 have a total cholesterol of 200 mg/dl and above, which is considered elevated but a survey by the American Heart Association found that 76 percent of women say they dont even know what their cholesterol values are, Michos says.
Scarier still: Triglycerides, a type of blood fat typically measured alongside cholesterol, are even more risky in women compared with men. This is a problem because womens cholesterol levels can fluctuate quite a bit after menopause and tend to increase with age, putting us at greater risk of heart disease and stroke. Knowing your cholesterol numbers and how to control them is a big step toward staying healthy.
Does Hdl And Ldl Equal Total Cholesterol
Asked by: Virginie Willms
When your cholesterol is checked, you get a number for total cholesterol, one for the HDL level, and one for the LDL level. Your total cholesterol will be more than the sum of the HDL and LDL numbers. Either a high HDL number or a high LDL number can make your total cholesterol number high.

How To Lower Cholesterol: Know Your Fats
The American Heart Association recommends that just 25% to 35% of your daily calories come from fats such as those found in fish, nuts, and vegetable oils. For healthy people, saturated fat should comprise no more than 7% of your total calories. On a 2,000 calorie-a-day diet, that’s about 140 calories worth of saturated fat. If you need to lower your LDL cholesterol, limit saturated fat to 5% to 6% of calories, or about 11 to 13 grams of saturated fat on a 2,000-calorie diet. Reduce trans fats to less than 1% of your total daily calories. This means avoiding fried foods and many junk foods.
What Does Ldl Cholesterol Do
LDL is considered the bad cholesterol. It carries cholesterol to your arteries, where it may collect in the vessel walls and contribute to plaque formation, known as atherosclerosis. This can lead to decreased blood flow to the heart muscle , leg muscles , or abrupt closure of an artery in the heart or brain, leading to a heart attack or stroke. Over a third of the US population has high LDL cholesterol. Diagnosis is made via blood testing, so if you dont check, you wont know.
For LDL, the lower the number the better. A good goal to keep in mind is less than 130 mg/dL if you dont have atherosclerotic disease or diabetes. It should be no more than 100 mg/dL, or even 70mg/dL, if you have any of those conditions or high total cholesterol. Its very important to set your own target cholesterol levels with your doctor. Obesity, a large waist circumference, a sedentary lifestyle, or a diet rich in red meat, full-fat dairy, saturated fat, trans fats, and processed foods can lead to high LDL cholesterol.

What Causes High Cholesterol
Your liver produces cholesterol, but you also get cholesterol from food. Eating too many foods that are high in fat can increase your cholesterol level.
Being overweight and inactive also causes high cholesterol. If you are overweight, you most likely have a higher level of triglycerides. If you never exercise and arent active in general, it can lower your HDL .
You family history also affects your cholesterol level. Research has shown that high cholesterol tends to run in families. If you have an immediate family member who has it, you could have it, too.
Smoking also causes high cholesterol. It lowers your HDL .

What Are Hdl And Ldl
Good cholesterol is one of the groups of lipoproteins present in blood. HDL aids in the transport of cholesterol and triglycerides to the liver for excretion or re-utilization. Thus, good cholesterol prevents cardiovascular diseases by preventing the blockage of arteries.
Bad cholesterol is also a type of lipid present in the blood and if present in large amounts can cause health problems as it tends to accumulate in the arteries and cause blockage.
In fact, not all LDL causes atherosclerosis. There are two types of LDL: small dense LDL and large buoyant LDL. It is the small dense LDL that is more atherogenic. Small dense LDL enters the walls of blood vessels. When LDL gets oxidized, plaque builds up in the arterial walls, causing the obstruction of blood vessels.

How To Increase Hdl Cholesterol
Although HDL levels are driven by family genetics, you can improve HDL levels in three key ways:
- If you are a smoker, research clearly shows that quitting smoking can increase HDL.
- Adopting a heart-healthy diet low in fat and high in fiber can also modestly raise your HDL.
- Aerobic exercise can also have positive effects on HDL. Have trouble exercising? Find a buddy research shows it helps motivate you. That exercise can be as simple as increasing the amount of walking you do each week.
Lastly, although primarily used to decrease high LDL, some statin medications may potentially increase HDL levels moderately. Any medical treatment option should be discussed with your doctor. Importantly, high HDL does not protect you from the untoward effects of high LDL.
What Are Cholesterol Levels
- LDL cholesterol is often referred to as “bad” cholesterol because too much of it can build up in your arteries and form plaques, which increases the risk of heart disease .
- HDL cholesterol is often referred to as “good” cholesterol as it carries cholesterol to the liver to be broken down and excreted.
Since your total cholesterol is a combination of your LDL cholesterol and your HDL cholesterol, ideally you want to keep your LDL levels low and your HDL levels high. There are many factors that can influence your cholesterol, including, diet, exercise, weight, genetics, and other health conditions.

What Affects Cholesterol Levels
There are a variety of factors that can affect cholesterol levels. Some risk factors are within your control, while others are not:
- Genetics: These factors include familial hypercholesterolemia and a family history of heart disease.
- Sex: Males often have higher levels of LDL. After menopause, a woman’s LDL levels can also increase.
- Weight: People who are overweight or obese are at increased risk of having high cholesterol.
- Sedentary lifestyle: Lack of physical activity can increase the risk of overweight and obesity and, in turn, increase cholesterol levels.
- Diet: Overall diet quality can affect cholesterol in a negative way, including eating too many saturated and trans fats and not enough fiber.
- Age: Your body’s ability to clear cholesterol can be impacted as you age.
- Race and ethnicity: There are different rates of high cholesterol based on race/ethnicity and sex, with the highest rates among males in Hispanics and the highest rates among females in non-Hispanic Whites.
- Smoking: Smoking can increase your bad cholesterol and lower your good cholesterol.
- Other medical conditions: Having a previous history of high cholesterol, heart disease, or diabetes can increase your risk of developing high cholesterol.
What Are ‘normal’ Cholesterol Levels
The only way to know your cholesterol levels is through a blood test. You need to know your total cholesterol , as well as HDL and LDL. Triglycerides are another type of fat, related to, but different from cholesterol. High levels of triglycerides are also linked to heart disease. Here are what the numbers mean:
- Less than 200 is desirable
- Between 200 and 239 is borderline high
- From 240 up is considered high
- Less than 100 is optimal
- Between 100 and 129 is almost optimal
- Between 130 and 159 is borderline high
- Between 160 and 189 is considered high
- And 190 and above is deemed to be very high
- 60 and above is optimal
- Less than 40 for men is considered low
- Less than 50 for women is considered low
- Avoid full-fat dairy products. Instead, opt for skim milk, lower fat cheese, lower fat yogurt and trans-fat free spreads.
- Substitute heart healthy plant oils for butter and lard.
- Eat lean proteins: fish, skinless chicken, and lean meats. Avoid marbled meats and bacon.
- Body weight: Losing weight can help lower cholesterol. Regular exercise can increase HDL and lower LDL . Thirty minutes per day can have healthy benefits.
- Smoking: Dont do it.
Biology: We cant control
- Age: As we all age, cholesterol rises.
- Gender: After menopause, women are at greater risk for higher cholesterol.
- Heredity : Your genes can determine how much cholesterol your liver produces.
- Diabetes: This disease can alter the balance of LDL and HDL cholesterol.
