What Cholesterol Really Is

By Kim Bailey

Today's health gurus spend plenty of time talking about cholesterol. You might be surprised to find out that this substance is actually necessary for the body. It is used to build cell walls that help the body produce necessary substances like hormones and bile. However, the body doesn't need much cholesterol to function properly. When it begins to build up, it can have a detrimental effect on the cardiovascular system specifically and the rest of the body overall.

Cholesterol In Small Amounts Are Good

The good cholesterol becomes a problem when there are too much and the body is unable to eliminate this excess from the system. The excess cholesterol then builds up as a plaque in the arteries and in doing so blocks the flow of blood.

By interfering with the flow of blood through the body, high cholesterol places a strain on the heart by causing it to have to work much harder to keep blood flowing through the body and it is this strain on the heart that increase our risk of heart attack.

This is why monitoring cholesterol levels becomes so important throughout adulthood. When high levels are detected, a doctor and patient can work together to bring amount back down through diet, exercise and medication. The good news is that most people can prevent or reverse high levels through these methods, allowing the heart to return to normal function. The key factor is to track cholesterol on a regular basis, so you know if levels are beginning to rise as soon as possible.

Types

There is more than one type of cholesterol found in the body. The first is low density lipoproteins, or LDL. LDL delivers cholesterol to the body, so the lower the number of LDL, the better for the patient. High density lipoproteins, or HDL, help remove cholesterol from the bloodstream.

Needless to say that a higher HDL will therefore mean lower cholesterol and a healthier cardiovascular system. Experts figure the two numbers together to work out what an overall healthy cholesterol reading is.

Understanding what cholesterol is and how it can both benefit and negatively influence the cardiovascular system is an important step towards heart health. Regular monitoring of your cholesterol levels is an important step towards making the necessary changes for a healthier heart.

If you are unsure of where your levels are at, talk to your doctor about a cholesterol screening. This simple blood test can provide plenty of valuable information about how to keep your body in the healthiest condition possible.
