High cholesterol levels. Computer illustration of balls of cholesterol in a blood vessel. Cholesterol is a lipid, a fat-like substance. High blood levels of LDL (low-density lipoprotein) cholesterol compared to HDL (high-density lipoprotein) cholesterol are thought to raise the risk of atherosclerosis, the build-up of fatty deposits on artery walls. This is a major cause of heart attack and stroke. | |
