What causes high cholesterol?

Published

on

Cholesterol is both good and bad. At normal levels, it is an essential substance for the body. However, if concentrations in the blood get too high, it becomes a silent danger that puts people at risk of heart attack.

Cholesterol is found in every cell of the body and has important natural functions when it comes to digesting foods, producing hormones, and generating vitamin D. It is manufactured by the body but can also be taken in from food. It is waxy and fat-like in appearance.



There are two types of cholesterol; LDL (low-density lipoproteins, bad cholesterol) and HDL (high-density lipoproteins, good cholesterol).

In this article, we will explain the role of cholesterol. We will also discuss the causes of high cholesterol, and its symptoms, treatment, and prevention.

Fast facts on cholesterol:

  • Cholesterol is an essential substance that is produced by the body but is also ingested from animal-derived foods.

  • The greatest risk factors for high cholesterol are modifiable lifestyle choices – diet and exercise.

  • Having high cholesterol does not usually produce any symptoms.

  • If lifestyle changes are unsuccessful or cholesterol levels are very high, lipid-lowering drugs such as statins may be prescribed.

    What is cholesterol?

    Cholesterol is an oil-based substance and does not mix with the blood, which is water-based. It is carried around the body by lipoproteins.

    Two types of lipoprotein carry the parcels of cholesterol:

    • Low-density lipoprotein (LDL) – cholesterol carried by this type is known as “bad” cholesterol.

    • High-density lipoprotein (HDL) – cholesterol carried by this type is known as “good” cholesterol.

    Cholesterol has four primary functions, without which we could not survive, these are:

    • contributing to the structure of cell walls

    • making up digestive bile acids in the intestine

    • allowing the body to produce vitamin D

    • enabling the body to make certain hormones

    Causes of high cholesterol

    High cholesterol is a significant risk factor for coronary heart disease and a cause of heart attacks. A build-up of cholesterol is part of the process that narrows arteries, called atherosclerosis, in which plaques form and cause restriction of blood flow.

    Reducing intake of fat in the diet helps manage cholesterol levels. In particular, it is helpful to limit foods that contain:

    • Cholesterol – from animal foods, meat, and cheese.

    • Saturated fat – found in some meats, dairy products, chocolate, baked goods, deep-fried, and processed foods.

    • Trans fats – found in some fried and processed foods.

    Being overweight or obese can also lead to higher blood LDL levels. Genetics can contribute to high cholesterol – very high LDL levels are found in the inherited condition familial hypercholesterolemia. Abnormal cholesterol levels can also arise due to other conditions, including:

    • diabetes

    • liver or kidney disease

    • polycystic ovary syndrome

    • pregnancy and other conditions that increase levels of female hormones

    • underactive thyroid gland

    • drugs that increase LDL cholesterol and decrease HDL cholesterol (progestins, anabolic steroids, and corticosteroids).
