High Cholesterol

High cholesterol is a medical condition in which there is an abnormally high level of cholesterol in the blood. Cholesterol is a type of fat (lipid) that is an essential part of all cells in the body. It is made mainly by the liver and is necessary for the normal functioning of cells. When there is too much cholesterol in the blood, it can build up in the walls of the arteries and cause them to narrow and harden, resulting in a condition known as atherosclerosis. This can lead to a number of serious health problems, such as coronary artery disease, stroke, and peripheral artery disease. High cholesterol is a major risk factor for heart disease and stroke. High cholesterol can be caused by a number of factors, including an unhealthy diet, lack of physical activity, smoking, and certain medical conditions. It is also commonly inherited. Treatment for high cholesterol typically involves lifestyle changes, such as eating a healthier diet, exercising more, and quitting smoking, as well as medications. It is important to treat high cholesterol, as it can reduce the risk of developing serious health problems.
