Cholesterol is a fatty substance that is essential for many important functions in the body. Although it is often associated with negative health effects, cholesterol is necessary for the body to function properly. Here are some of the functions of cholesterol:

• Cell membrane formation: Cholesterol helps your cell membranes form protective layers that control what can enter or leave your cell.

• Bile production: Cholesterol helps your liver make bile, which is necessary for digesting food.

• Hormone and vitamin D production: Cholesterol supports your bodys production of certain hormones, including sex hormones, and vitamin D.

While cholesterol is necessary for the body to function properly, too much of it can be harmful. High levels of low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, can lead to plaque buildup in the arteries and increase the risk of cardiovascular disease, including heart attack and stroke. Therefore, it is important to maintain healthy cholesterol levels through a balanced diet, regular exercise, and medication if necessary.
