So those numbers the doctor gave you. What exactly do they mean? What is the relationship between your HDL and LDL and why is it important to use the two to determine your cardiac risk? And what types of Cholesterol is she talking about?
Total cholesterol is both your HDL and LDL together. That doesn’t really tell you much. You need to know the number for each and examine the relationship between the two to determine your cardiac risk. More than 30% should be HDL cholesterol. To figure out the percentage take your HDL number and divide by the total number. Percentages between 30-40% are excellent and over 40% shows a very low risk of heart attack. If the percentage is less than 20% you are more at risk and if the percentage is 10% or below you are in great danger of having a heart attack.
For most of us cholesterol can be managed with a healthy lifestyle. If your levels of cholesterol are on the high side it could mean your body is giving you a warning and it would be a good idea to review the type of lifestyle you live. It is recommended that you visit your physician on a regular basis to keep a keen eye on your levels.
The purpose of this website is to inform, educate and provide healthful options so you can make better decisions on how to obtain a healthy cholesterol level.
While most people talk about “cholesterol levels” there is in fact more than one type of cholesterol. In fact, there are several different body functions and several different substances that make up our understanding of “cholesterol.”
As with some fats, cholesterol cannot be dissolved in the blood. Instead, molecules called lipoproteins carry cholesterol to and from cells. Molecules are made from an outer layer of protein and an inner core of both cholesterol and triglycerides, which is another form of fat.
Lipoproteins equip the cholesterol to move around the body. The two main types of lipoproteins are:
1) High Density Lipoproteins (HDL)
• HDL transports cholesterol from cells back to the liver.
• HDL is either reused or converts to bile acids and disposed. This is known as “good” cholesterol. You want to ensure that your levels of this cholesterol remain high for optimum heart health, since having too low levels of HDL – even when other cholesterol levels are normal – may lead to heart problems. As you work to lower your “bad cholesterol” it is important to also take steps and to keep your HDL levels normal.
• HDL aids to ensure protection from the risk of heart attack and/or stroke. HDL consists of more protein than triglycerides or cholesterol, and aids to remove LDL from your artery walls.
2) Low Density Lipoproteins (LDL)
• LDL carries approximately 60-70% of cholesterol around the body and are known as “bad” cholesterol.
• Studies have shown that high cholesterol leads to much higher risk of heart attack and/or stroke. But exactly what is a high level. Drug companies keep lowering the numbers adding more confusion. Other factors involved in this risk are age, gender, smoking, family history of heart disease, and diabetes mellitus.
Obviously, when we speak of having “cholesterol levels” we mean more than one number. To maintain optimum health, you will need to know your levels of both LDL and HDL and will need to work hard to keep both levels in healthy ranges.
This is actually a simplified answer for the types of cholesterol. Actually according to Dr. Ron Rosedale there is no “good” or “bad” cholesterol, cholesterol is just cholesterol. The LDL proteins come in different sizes though and it is the small particles that can potentially be a problem because they can squeeze through the lining of the arteries, oxidize and become rancid. He also says that some HDL particles are better than others. So he thinks just knowing your total cholesterol level tells you very little and even knowing the LDL and HDL levels doesn’t really tell the whole story.
