Cholesterol plays an important role in the body in building tissues and organs and in the production of certain hormones and bile acids. A small part of all cholesterol is found in the blood in the form of fat particles, so-called lipoproteins. The desired amount of cholesterol is 5,0 mmol/l or lower. This does not increase the risk of cardiovascular disease. Cholesterol between 5 mmol/l and 6.5 mmol/l slightly increases the risk of cardiovascular disease. Cholesterol above 6.5 mmol/l increases the risk of cardiovascular disease. Based on a lipid profile and other tests, the cause of the high cholesterol can be further investigated.
