Hypercholesterolemia, also called high cholesterol, is the presence of high levels of cholesterol in the blood. [1] It is a form of hyperlipidemia (high levels of lipids in the blood), hyperlipoproteinemia (high levels of lipoproteins in the blood), and dyslipidemia (any abnormalities of lipid and lipoprotein levels in the blood). [1]
Hyperlipidemia is abnormally high levels of any or all lipids (e.g. fats, triglycerides, cholesterol, phospholipids) or lipoproteins in the blood. [2] The term hyperlipidemia refers to the laboratory finding itself and is also used as an umbrella term covering any of various acquired or genetic disorders that result in that finding. [3]
The human body makes one-eighth to one-fourth teaspoons of pure cholesterol daily. A cholesterol level of 5.5 millimoles per litre or below is recommended for an adult. The rise of cholesterol in the body can give a condition in which excessive cholesterol is deposited in artery walls called atherosclerosis. This condition blocks the blood flow ...
Levels are high if: Total cholesterol is 240 or higher. LDL cholesterol is 160 or higher. HDL cholesterol is under 40 for men, or under 50 for women. Why cholesterol build-up is harmful.
HDL cholesterol is “good” cholesterol and high levels of it can lower the risk of heart disease and stroke. Interventional cardiologist and Reveal Vitality founder Dr. Christopher Davis, ...
Normal LDL cholesterol levels are associated with the build-up of atherosclerotic plaques in our arteries even in those with so-called optimal risk factors by current standards: blood pressure ...
For instance, someone's total cholesterol may be high, but this may be due to very high HDL ("good cholesterol") cholesterol levels,—which can help prevent heart disease (the test is mainly concerned with high LDL, or "bad cholesterol" levels). So, while a high total cholesterol level may help give an indication that there is a problem with ...
Those with higher levels of HDL-C tend to have fewer problems with cardiovascular diseases, while those with low HDL-C cholesterol levels (especially less than 40 mg/dL or about 1 mmol/L) have increased rates for heart disease. [8] [needs update] Higher native HDL levels are correlated with lowered risk of cardiovascular disease in healthy people.
