High cholesterol is the main culprit of cardiovascular disease, and it has been found through surveys that for every 1% increase in cholesterol, the risk of having coronary heart disease increases to 2%. Common causes of high total cholesterol include improper diet, excessive intake of foods containing high cholesterol, such as heart, liver and other animal offal, causing high total cholesterol, which is the main cause of high total cholesterol; and hereditary hypercholesterolemia and certain diseases, such as obstructive jaundice, which causes high total cholesterol due to obstructed bile drainage.
