What Is LDL Cholesterol?

Cholesterol is a substance that is found in all the cells of the human body and is among the fats in the bloodstream. Though cholesterol is necessary for bodily functions, it is dangerous if not kept in moderation, and LDL (low-density lipoprotein) cholesterol is the most harmful type.

  1. Cholesterol

    • Cholesterol is needed to form cell membranes and certain hormones in the human body. But its waxy texture and its inability to be dissolved by the blood can turn it into artery-clogging plaque. A high level of cholesterol in the blood could cause coronary heart disease.

    Lipoproteins

    • Lipoproteins transport cholesterol throughout the body by enveloping and carrying the insoluble material along the water-based solution within the bloodstream, and they are necessary for it to be moved to where it is needed.

    LDL

    • LDL is the prevalent cholesterol carrier in the blood. They are the carriers that transport cholesterol from the liver to tissues in the general area of the liver, and from there to the arteries.

    Significance

    • Because LDL is responsible for holding and carrying cholesterol to the arteries, the conjunction of the two often finds itself retained in them if the levels are too high. Then, the LDL cholesterol starts to build up and form plaque within the arteries, causing cardiovascular problems.

    Misconceptions

    • The actual cholesterol that is LDL cholesterol is not bad, as it is the same cholesterol that is considered healthy. What makes it dangerous is the fact that it is being transported to areas in which blood flow must be high, and its concentration and size in these areas are likely to cause health problems.

    Health Problems

    • Tests are routinely done to measure levels of LDL cholesterol. High levels could lead to increased plaque, causing atherosclerosis, a narrowing and rigidity of arteries, which in turn will increase the likelihood of a person suffering vascular disease, heart attack or stroke.
