The Basics of Cholesterol

Cholesterol is a waxy, fat-like substance that is found in every cell of the body. It plays a crucial role in various bodily functions, such as building cell membranes and producing hormones. However, having high levels of cholesterol in the blood can increase the risk of developing heart disease and other health problems. In this section, we will explore the basics of cholesterol and how genetics can influence cholesterol levels.

Cholesterol is classified into two main types: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL cholesterol is often referred to as “bad” cholesterol because it can build up in the arteries, leading to atherosclerosis and an increased risk of heart disease. On the other hand, HDL cholesterol is known as “good” cholesterol because it helps remove LDL cholesterol from the bloodstream, reducing the risk of heart disease.

Genetics play a significant role in determining an individual’s cholesterol levels. Some people may have a genetic predisposition to high cholesterol levels, making them more susceptible to developing heart disease. Understanding your genetic risk factors can help you take proactive steps to manage your cholesterol levels and reduce your risk of heart disease.
