Cholesterol Levels and Ratios – Are Your Cholesterol Numbers Confusing You?

June 18, 2010 · Posted in cholesterol · Comment 

Cholesterol levels are being tested all over the world in order to determine risk factors for heart disease, yet  many people are confused by their cholesterol numbers and how they are expressed.  Part of this confusion may stem from the fact that literature originating in the United States gives cholesterol levels in units that are different from those used in Canada, Europe, and a good portion of the rest of the developed world.  So when you are looking for information to help you understand your test results, on the internet and elsewhere, you might not  understand the numbers that are reported in the American literature because they might look quite different from the cholesterol numbers on your lab report.

The United States reports cholesterol levels in mg/dL (milligrams per decilitre) of blood.  The rest of the world is using the measurement called mmol (or millimoles per litre).  Without going back to basic chemistry from high school, let’s just say  that they are different measurements. So is it any wonder that these two ways of expressing your cholesterol numbers are so different?

Here is how the two different systems of measurement stack up for desirable cholesterol numbers.

As expressed in the system of measurement used in the United States

Total cholesterol = less than 200 mg/dL LDL  = less than 100-129 mg/dL (below 100 is best) HDL  = more than 40 mg/dL (greater than 60 is considered protective against heart disease)

However, as expressed in the SI units (International System of Measurement) that most of the world is using the numbers are stated differently. (You can remember which letters refer to the good and the bad stuff by remembering it this  way…H stands for healthy  and L stands for lousy.)

Total cholesterol = less than 5.2 mmol/L LDL  = in the range of than 2.6 – 3.3 mmol/L (less than 2.6 is best) HDL  = in the range of more than 1 to 1.5 mmol/L (higher is better) mmol/L

Can you see the difference in how the cholesterol numbers are expressed?  The difference of course is in the units that are being measured. Think of it like metric and imperial measures. Your weight in pounds might be a three digit number but in kilograms it could be a two digit number. Same weight different measurements.

Understanding the Cholesterol Ratio

When used to determine if you have cholesterol risk factors for heart disease it is not the specific levels that are analyzed but rather the ratio of HDL in your total lipid profile. This number is called the cholesterol ratio and it gives an indication of how much of your total cholesterol is the “good” stuff.

The reason this is important is because the HDL is so beneficial, if it is present is sufficient quantities it  has a protective effect and  the LDL in your system cannot do as much damage.  So even if your LDL is higher than the desired levels, if the HDL is high as well and the ratio comes within the desired range then the risk of heart disease is less.

The goal is to keep the cholesterol ratio below 5:1; the optimum ratio is 3.5. The cholesterol ratio comes in at the same number no matter which system of measurement is used. The cholesterol ratio is obtained by dividing the total cholesterol number by the value given for the HDL. For example, if a you have a total cholesterol of 240 mg/dL and an HDL of 60 mg/dL,  the ratio is 4. Using the SI system of measurement if the total cholesterol is 7.20 mmol/L and the HDL is 1.8 mmol/L  the ratio is still 4.

You can see how this is a better way of understanding the cholesterol risk factors for heart disease and expressing it this way can prevent confusion that might result from not being familiar with the units that are used. This information is also helpful for understanding why the strategies recommended  for cholesterol imbalances work. Some of the best strategies are the ones that raise the HDL levels.  In particular, exercise has been found to be one of the best ways to improve the cholesterol ratio because it raises HDL levels.  By contrast smoking has been found to lower HDL levels so no exercise and smoking is a recipe for low HDL levels, a poor cholesterol ratio, and a higher risk for heart disease.

Cholesterol is found in every cell of the body and is essential for the maintenance of good health.  Low cholesterol levels have been associated with poor health so the goal is not to eliminate or reduce cholesterol entirely but to obtain the desirable levels of each type so that the protective benefits of the HDL can work for you in maintaining good health.

So don’t get mixed up when trying to understand your cholesterol levels.  No matter what way the numbers are expressed the message is the same.  You want to have enough of the good stuff and not so much of the bad stuff in order to reduce your risk factors for heart disease.

Cholesterol Levels And Ratios – Are Cholesterol Numbers Confusing You?

Cholesterol levels are being tested as part of regular health screening all over the world yet many people are confused by their cholesterol numbers and how they are expressed.

Here is how the two different systems of measurement stack up for desirable cholesterol levels.

* Total cholesterol = less than 200 mg/dL
* LDL = less than 100-129 mg/dL (below 100 is best)
* HDL = more than 40 mg/dL (greater than 60 is considered protective against heart disease)

However, as expressed in the SI units (International System of Measurement) that most of the world is using the numbers are stated differently. (You can remember which letters refer to healthy and lousy by remembering it this way…H stands for healthy lipoprotein and L stands for lousy lipoprotein.)

* Total cholesterol = less than 5.2 mmol/L
* LDL = in the range of than 2.6 – 3.3 mmol/L (less than 2.6 is best)

Diet to Lower Cholesterol – A Simple Explanation of Just What is Cholesterol

March 2, 2010 · Posted in cholesterol · Comment 

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 Importance Of Taking A Cholesterol Test

January 21, 2010 · Posted in cholesterol · Comment 

High cholesterol levels can be a sign of potential heart disease. High levels of HDL cholesterol can be a warning sign of hardening of arteries that can result in heart disease or a heart attack. Even though high cholesterol is a very serious and fatal condition, there are no symptoms to warn you if you are having high cholesterol levels.

To know your cholesterol levels you must take a cholesterol test. As high cholesterol levels can be life threatening, and coronary heart disease is a common occurrence when you have high levels of bad cholesterol you should get a cholesterol test regularly.

Cholesterol is made of two main types: HDL, or the good cholesterol which actually helps prevent heart disease and LDL or bad cholesterol which will clog your arteries and cause heart disease if present in high levels in your body. The right level of cholesterol should be 200mg/dl of LDL or less and at least a minimum of 40mg/dL of HDL or more.

Cholesterol test is done through a blood test that will tell you the levels of both types of cholesterol in your body. This test can be done at the hospital. There are also home test kits for cholesterol testing available. However, tests done in the hospital are more reliable and you should go to the hospital for your first cholesterol test.

If your cholesterol test result show that your bad cholesterol level is too high, your doctor can advise you on how to lower it. He will probably advise you to change your diet and do more exercise. If you cholesterol levels are very high or you have other medical condition like diabetes, he may prescribe you with cholesterol lowering medication. Most doctors recommend that anyone over the age of 20 should take a cholesterol test once every five years.

The Cholesterol Test Kit

Today there is a way to test your cholesterol levels without having to leave your home. A home cholesterol test kit can be purchased from any drug store. This home test kit consists of the tools required to conduct an accurate cholesterol test. With only a couple drops of your blood you will be able to tell the cholesterol levels present in your body in ten minutes time.

The home cholesterol test kit is FDA approved and is available over the counter for you to purchase and use when needed. It has a 97% accuracy rate and is very easy. The home cholesterol test kit cost about $25 for a pack of two test kits. Some cholesterol test kits are sold with only one test strip but the two tests package is more economical. Everyone who wants or needs to keep check their cholesterol level regularly without having to go to a hospital can use the handy cholesterol test kit.

Home Cholesterol Test Kit May Not Always Be Accurate

Although nowadays you can get all kinds of home kits for many medical problems, some of the results from the tests carried out by these kits may not be very accurate. However, the fault may not lie with the test kit itself, but it may lie in the way it is used. The home cholesterol test kit too seldom gives accurate results because it is usually administered wrongly.

That is the reason why doctors do not like to rely on the results of home cholesterol test. If you go for treatment for high cholesterol level, your doctor will ask you to take another test from the lab. The doctor will only proceed with treatment after they get the lab tests results.

The home cholesterol test kit may be useful if you can get your a physician to administer it for you. This is so that after the test is done, he can interpret the results for you. This is why it is better to take a lab test rather than simply buying a home cholesterol test.

Any home cholesterol test done with a home test kit should be repeated in the doctor’s lab for double confirmation, so that if your cholesterol home test results are actually not accurate, you will know it before you undergo any form of cholesterol lowering treatment.

If you do prefer a home cholesterol test kit than going to the hospital for a cholesterol test, you should still consult your doctor and have the test repeated before taking any form of drugs or medications.
