What causes high cholesterol?

Cholesterol is required by your body for a number of vital functions including the structure and function of cells.

Traditional cholesterol testing only gives your total cholesterol level, and is not the most useful indicator of whether you are at risk of diseases caused by hypercholesterolaemia (high cholesterol) such as heart disease and stroke.

Cholesterol Tests

At the Walk-in Clinic, we provide a comprehensive cholesterol profile, which is a good indicator of whether your cholesterol levels need adjustment through diet and exercise or require medication.

Your total cholesterol is made up of LDL cholesterol (low-density lipoprotein) and HDL (high-density lipoprotein). A high level of LDL cholesterol directly increases your risk of heart disease, stroke and other diseases.

A high level of HDL cholesterol, however, is a favourable result, as this helps to protect against heart disease. HDL is helpful because it “scours” the walls of blood vessels, cleaning out cholesterol that might be clogging them.

The third element that you should test for is triglycerides. Triglycerides are the chemical form in which most fats exist in the body and are used for energy and for other body functions. However, a high level can contribute to life-threatening diseases like heart disease and stroke.


High levels of cholesterol can be caused by various factors, including:

  • Genetic factors (family history): Some individuals inherit a genetic predisposition for high cholesterol, known as familial hypercholesterolemia, which can lead to elevated levels regardless of diet.
  • Diet: Consuming foods high in saturated and trans fats, such as fried foods, red meat, full-fat dairy products, and baked goods, can raise cholesterol levels.
  • Lack of exercise: Regular physical activity helps lower “bad” LDL cholesterol and raise “good” HDL cholesterol.

What is cholesterol?
Cholesterol is a substance made by the liver. It is waxy and similar in consistency to fat. It is also found in food. Cholesterol is found in the cell membranes of every part of the body, and is crucial for normal bodily functioning.
There are a number of possible causes of high cholesterol, but it can indicate that the body is working harder than normal to maintain balance. Certain diets (especially those high in saturated fats) can raise cholesterol levels, as can lack of exercise or overweight. In some cases, high cholesterol is inherited from family members.
HDL, known as “good cholesterol”, supports the liver’s filtration and cleansing of cholesterol. LDL (“bad cholesterol”) just circulates cholesterol. Thus, HDL is actually a protector, whereas LDL can accumulate as plaque and clog arteries.
