What You Should Know About Cholesterol Testing
When should I undergo a cholesterol test? What would the results say about my health? How many tests are there and which will give me the best results?
Unlike any other health tests, cholesterol testing does not diagnose disease. Instead, it reveals the risks of developing heart disease. Cholesterol testing is considered necessary in preventive health care for individuals over 20 years of age. The test should be repeated once every five years for healthy individuals.
Cholesterol testing, along with HDL, LDL and triglyceride testing is called the lipoprotein profile.
Cholesterol testing is done several times a year for individuals who are on a prescribed diet and for those who are taking cholesterol lowering medications.
Usually blood samples are drawn from the arm. Sometimes blood samples are taken from the fingertip. The samples are analyzed by a cholesterol testing device. Cholesterol tests are used to monitor the progress in lowering the cholesterol level.
Test results are grouped in three types:
* Desirable – the cholesterol level of 200 mg/dL below is regarded to be desirable because it has a low risk of heart disease.
* Borderline high – a total cholesterol level of 200 mg/dL to 240 mg/dL is at fair risk of having heart disease. Your doctor may decide to give you have a lipid profile in order to determine which cholesterol level is high.
* High Risk – a 240 mg/dL cholesterol level is considered to be at high risk of heart disease. Expect a lipid profiling if your cholesterol level is this high. It is more likely that you will be given a cholesterol lowering medication along with a low cholesterol diet.
Cholesterol tests are usually given when the individual is healthy because the blood cholesterol level of an individual who has an acute illness, (after a heart attack or after surgery or accident) is likely to be low. Individuals are advised to wait at least six weeks after any illness before taking cholesterol tests. Pregnant women are also advised to wait six weeks before having their cholesterol level measured.
A Brief Explanation of Cholesterol Ratios:
Cholesterol ratios consist of total cholesterol. Total cholesterol includes low level lipoprotein cholesterol levels (LDL cholesterol), triglycerides and high density lipoprotein cholesterol level (HDL cholesterol).
Cholesterol is measured by milligrams of cholesterol per deciliter of blood (mg/dL). Usually, only the total cholesterol amount is given when a person is tested for cholesterol. Sometimes you are given the HDL cholesterol and the total cholesterol results.
The desirable total cholesterol level is 200mg/dL and the beneficial amount of HDL is more than 40mg/dL.
There are two important cholesterol ratios. These they are LDL/HDL cholesterol ratios and total cholesterol/HDL cholesterol ratios.
In the latter cholesterol ratios, your cholesterol result is given by the total cholesterol divided by the HDL cholesterol. According to the American Heart Association, the desirable amount should be below 5:1 with the optimal amount of 3.5:1 or 3.5 to 1.
The LDL/HDL is done by dividing LDL cholesterol by the HDL cholesterol. The desirable amount in this ratio should be 3.5 below. The American Heart Association recommended that physicians must use complete numbers for total cholesterol/HDL cholesterol in determining the appropriate treatment.
A normal cholesterol level as suggested by the National Institute of Health:
* total cholesterol – 200mg/dL
* LDL – 100mg/dL
* HDL (man) – 40mg/dL above
* HDL (woman) – 50mg/dL above
* Triglycerides – 150mg/dL
It is important to remember to fast the night before, prior to taking a lipid profile test (a test that profiles the HDL cholesterol, triglycerides and total cholesterol) the next day.

Why You Should Be Lowering Blood Cholesterol Naturally
Lots of people want to know about ways to lower cholesterol naturally. Fortunately, there are answers available. It is important to first know there is no magic pill for reducing cholesterol levels. What is essential is that you are keeping to a diet that is particularly designed to lower cholesterol levels. To lower the level of cholesterol in your body you should also get some exercise on a regular basis.
What is Cholesterol?
Cholesterol is a substance that is soft and waxy and can be seen in the cells of your body.
Our bodies make use of cholesterol to function efficiently. The body also makes use of cholesterol in making other valuable substances such as Vitamin D and hormones that help to properly digest food.
Understanding Normal Cholesterol Levels
Doctors use a specially graded chart to determine whether or not yours can be considered normal cholesterol level or whether your cholesterol level is too high.
If you have lower than 200 mg/dL, it means your cholesterol level is under control. If the chart shows that your level is higher than 200 mg/dL but lower than 239 mg/dL, then it is not bad but you still need to be careful. If your cholesterol level is in excess of 240 mg/dL, then you have high cholesterol.
You can find many natural means that you can use to reduce cholesterol if you find that your level of cholesterol is on the higher side. However, not all cholesterol is bad. HDL cholesterol is beneficial to you. LDL cholesterol is the one that is considered harmful.
Ways of Lowering LDL Cholesterol
Low density lipoprotein, also called LDL, is the cholesterol that is considered bad for health. It carries cholesterol to the body tissues that use it to function. When you regularly consume excessive amounts of cholesterol your body often struggles to utilize it all. At this time LDL releases the surplus into the blood stream. This can be problematic as the extra cholesterol that is released keeps building up in the arteries. This constant build up leads to formation of plaque.
It is important to know how to lower ldl cholesterol by making dietary changes. It is best to avoid eating high cholesterol foods. You can easily find foods that help to lower cholesterol levels. Whole grains and oatmeal are some of the best.
How to lower Cholesterol Naturally
If you have been told that you have high cholesterol, but do not wish to take any kind of cholesterol medication, there are many alternative ways that you could use to reduce your levels of cholesterol naturally. One of the most valuable thing you can do is to eat plenty of foods that will reduce cholesterol levels and avoid those foods that are confirmed to be loaded with cholesterol. Some amount of exercise is a good option but it is best if used in conjunction with a diet that excludes high cholesterol foods.
Reducing your cholesterol by natural means will not happen overnight. But if you are determined, it is just a matter of time that you will see those cholesterol readings falling.
Lowering cholesterol naturally is not as effective for all. Many individuals would be advised to take medication. It is good to know though that you can reduce your cholesterol with medication and combine it with natural lowering methods as well. It is best to get your doctor’s advice before you embark upon any program for lowering your cholesterol using natural methods or with the prescribed medication
Lowering cholesterol naturally does take time but it can be achieved. You can find many different foods that can help you to keep normal cholesterol numbers. However, several individuals will have need of medication as well as natural cholesterol reducing measures.
Testing Cholesterol Level
Cholesterol is a substance which is found naturally in our blood and as a part of cell membranes. It is made by our liver but we can also get it with food we eat – animal products like meats, dairy fats, and egg yolks. Cholesterol is needed to make hormones and vitamin D. But cholesterol can also contribute to plaque formation in our blood vessels, a process called atherosclerosis and to increased risk of heart disease. In general cholesterol levels are largely determined by genetics – having a low level of cholesterol in our blood is natural and healthy but having a high cholesterol level can be dangerous.
To understand how cholesterol can contribute to atherosclerosis and heart disease, we should first understand where it is present and how it is carried around our body. Cholesterol is transported in the bloodstream with lipoproteins. Lipoproteins are special proteins of which two types are important in cholesterol transportation. High-density lipoproteins (HDL) transport cholesterol away from blood vessels (good for us), while low-density lipoproteins (LDL) can penetrate walls of our blood vessels, deposit cholesterol and form plaque (bad for us).
There are also other types of lipoproteins like very-low-density lipoproteins (VLDL), which are similar to low-density lipoproteins, but can more easily penetrate walls of our blood vessels; intermediate-density lipoproteins (IDL) like very-low-density lipoproteins, these also carry triglycerides and cholesterol; and chylomicrons which carry only a small percentage of cholesterol and are mostly rich in triglycerides (another type of fat).
High levels of LDL, IDL and VLDL lipoproteins contribute to increased risk of heart attack because these types of lipoproteins actually harm arteries. On the other hand, higher levels of HDL lipoproteins reduce risk of heart attack because these lipoproteins transport cholesterol away from the blood stream.
To keep cholesterol at safe levels we should focus on reducing LDLs while increasing HDLs. This can usually be done by taking care of what kind of food we eat. In order to know if we need to regulate our cholesterol level we should first measure it. For people older than 20 years it is advised to test cholesterol level every 5 years and adults over 45 years should have cholesterol test every few years.
The level of cholesterol in our blood is determined with a blood test. It can be done clinically or at home. There are many home cholesterol test kits available. Some tests measure only the total cholesterol level while others can measure also HDL and LDL levels. The cholesterol level in our blood is measured in units mmol/l. It is important to measure both types, LDL and HDL, because their ratio is also important – LDL to HDL ratio should be less than 4. Sometimes also the Cholesterol/HDL ratio is calculated. It is determined by dividing the total cholesterol level by the HDL cholesterol level and for most people this ratio should be below 5:1. The ideal Cholesterol/HDL ratio is below 3.5:1.
Normal cholesterol levels are the following:
- Total cholesterol level: less than 5.5 mmol/l
- LDL level: less than 3.5 mmol/l
- HDL level: greater than 1.0 mmol/l
- LDL to HDL ratio: less than 4
- Triglycerides level: less than 2.0 mmol/l
Cholesterol level can be lowered naturally. Foods rich in soluble fiber like fruits and vegetables, in particular citrus fruits and apples, have been shown to help decrease blood cholesterol level by binding it to fibers and thus preventing it from being absorbed into the body. Patients who have not improved their cholesterol levels with natural ways like with dietary and lifestyle changes can use cholesterol medications to regulate their cholesterol level.
Before investing in home cholesterol test kits, we should consult our doctor. Even when cholesterol testing is done by trained professionals in a lab, there can be significant variability in test results. The variability may be even greater with home cholesterol test kits, especially if we’re not fasting when we take the test. Home cholesterol test kits are widely available. They are practical, we can easily determine our total, HDL and LDL cholesterol levels in few minutes. However, we should be also aware of the accuracy of such home tests. Usually it is at least 95% but can vary. And we should also remember that home cholesterol tests don’t replace clinical cholesterol tests – nor do they offer an overall assessment of other risk factors for cardiovascular disease.

Diet to Lower Cholesterol – A Simple Explanation of Just What is Cholesterol
Many people understand that cholesterol is either bad for you or good but beyond that, they do not understand just exactly what is cholesterol. Doctors will give you a long explanation which only they can comprehend but cholesterol can be simplified in one statement. Cholesterol is a waxy material that the liver fabricates which is carries out a number of responsibilities for the health of our bodies.
When we consume foods in our daily diet, our liver takes the food and turns it into cholesterol which helps aid in developing bile salts to digest the fat, build cell walls, and to create vitamin D. So why would we worry about eating too many foods that produce too much cholesterol in our body? The answer lies in the fact that too much of anything is essentially bad for you. If we understand what is cholesterol, we can better steer clear of consuming to much cholesterol.
The Bad And Good Cholesterol.
One easy way to watch our cholesterol level is to understand what foods that we eat in our daily diet which produce the good cholesterol bad cholesterol. Foods that carry animal fat such as dairy and meats carry bad cholesterol, Foods such as vegetables, fruits, and whole grains carry no cholesterol at all.
When we eat foods that have too much bad cholesterol it can cause some major damage such as the hardening of our arteries. This occurs when too much bad cholesterol is in our system because it builds up plaque which blocks the arteries and prevents blood flow.
Good cholesterol behaves very differently than bad cholesterol because its main goal to keep our bodies healthy. What the good cholesterol does is carry the surplus of cholesterol we have in our bodies to the liver so it can create bile salt and expel it from our system.
High Cholesterol Is Caused By What?
When we ask our doctor about our cholesterol level, it is usually because we are worried about having a high cholesterol level. Having a high cholesterol level can be caused for many different reasons but the main cause is age. You see, our cholesterol level goes up as we get older.
There are many things that can cause us to get high cholesterol levels. One thing is we may inherit from our parents. If your parents have high cholesterol, you should ask your doctor to be tested to make sure if you have it or not. Another thing is doing physical activity. When we exercise and do any other physical activity, this causes our good cholesterol levels to rise thus keeping us healthy.
When we are looking at the causes and cures for high cholesterol, we often find a direct link between the food we eat and our cholesterol levels. If we eat foods rich in fiber, vegetables, beans, fish, and fruits we can keep the good cholesterol levels up within our body. We also need to try and avoid eating foods that promote high cholesterol levels within our body like meat and dairy products.When we go to the doctor and he gives us our cholesterol reading, many do not understand just exactly what he is talking about. Many people know that cholesterol is either good for you or bad, but many do not understand what is cholesterol. Cholesterol is simply a waxy matter that the liver creates which handles a number of duties in our body.

The Dangers And Causes Of High Cholesterol
As most of us may have read about, cholesterol is the fatty, wax like substance present in our cells and blood steam. Cholesterol has an important part in our body. This is because it produces cell membrane and contributes to a number of hormones as well. However, cholesterol can be dangerous to us if it is present in large amounts in our body.
The Two Types of Cholesterol
There are two types of cholesterol, one is the good cholesterol known as HDL or high density cholesterol and the other is the bad cholesterol known as LDL or low density cholesterol. The good cholesterol HDL, should be in levels of minimum 40md/dL or more and the bad cholesterol should be less than 200mg/dL.
The bad cholesterol is the cholesterol responsible for causing dieses including clogged arteries and can provoke a coronary heart disease.
What Causes High Cholesterol In Your Body?
High cholesterol level in your body is primarily due to the food products you consume which contain trans fat, saturated fats and cholesterol. This is the major cause of raising cholesterol levels in the blood stream. However, there is more than one cause of high cholesterol. Besides the foods you consume, excess weight, genes, gender and age all can cause high cholesterol levels.
Obesity is one of the major cause of high cholesterol as it occurs when the body mass is mostly made up of fat. Fat in turn, contain cholesterol. That is why, it is important to keep an ideal weight at all times.
Family’s health history transmitted through the genes is also a cause of high cholesterol levels. So, if anyone in your family has suffered from high cholesterol, you may have a tendency to suffer from it too. High cholesterol caused by heredity can be controlled with medication under a doctor’s supervision.
Men are found to be more prone to high levels of cholesterol in their teens while women become more prone to high cholesterol after menopause. Both men and women can control their cholesterol levels and maintain a normal level of cholesterol with proper health care and diet and with the right medication.
How To Prevent High Cholesterol
As most of the causes of high cholesterol are our own negligence in our diet and physical activities, we could easily manage our cholesterol level by modifying our diet and daily activities. We should pay more attention to the food we consume everyday and the amount of exercise we do everyday. This will help prevent and improve the levels of bad cholesterol in our body and maintain it at the right level.
Another factor that causes high cholesterol levels is triglyceride, which is a form of fat. It comes from food and is also made in your body. People with high triglycerides will often have a high total cholesterol level too.
The Importance of Understanding Your Cholesterol Level
It is extremely important to know your cholesterol levels. This is because having untreated high cholesterol can make you very prone to heart attacks and strokes. Although obesity is one of the most obvious causes of high cholesterol, just because you have an ideal weight does not mean that you have the right cholesterol level.
Basically your level of cholesterol can be categorized in one of three categories of cholesterol levels, which are: desirable, borderline risk, or high risk. You are considered as being in the desirable category if your total cholesterol is less than 200mg/dL, and the risk of getting a heart attack is relatively low, unless if you have other risk factors for the condition.
If your cholesterol is between 200 and 239mg/dL, you are considered in the borderline risk category. About a third of all people are in this category. If you are in the borderline category, you should check your cholesterol level at least once a year, especially if your HDL is less than 40mg/dL and/or you don’t have other risk factors for heart disease.
Lastly, if your cholesterol level is at 240mg/dL or more, you are in the high risk category. This means your risk of heart attack and stroke is very high. You will also have twice the risk of other coronary problems. If you are in this category, you must be more careful and start taking steps to improve your condition.
The most important to remember is lower LDL cholesterol, means lower total cholesterol level. Take all of the possible measures to keep your LDL cholesterol as low as possible. If you still are not able to lower your cholesterol, you can ask your doctor to prescribe medications to assist you in this process.
