What Is Cholesterol?

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.

Too Much of a Good Thing
The problem is that the body cannot effectively eliminate cholesterol from the body when it is found in excess. Instead, the substance remains in the bloodstream, forming a plaque in the arteries that makes it much more difficult for blood to pass through freely. When blood cannot flow as easily, the heart must work that much harder to keep the blood moving through the body. This puts a strain on the heart, and places the person at much higher risk for cardiovascular disease and a 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. A higher HDL generally means a healthier cardiovascular system. The numbers are figured individually and then factored together for a complete cholesterol level that provides a good indication of the overall health of the cardiovascular system.

Understanding cholesterol is an important step in keeping your cardiovascular system working in top condition. Regular monitoring of levels will let you know if you are on the right track with your health or if you need to make modifications to your diet and lifestyle 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.
