Cholesterol is a fatty substance present in the blood, and while the body needs it to build healthy cells, elevated levels can pose significant health risks. The medical terms for high cholesterol levels are hypercholesterolemia or hyperlipidemia, which refer to an increased concentration of cholesterol and other fats, such as triglycerides, in the bloodstream.Â
Action is necessary when your total cholesterol level exceeds 5 mmol/L. Elevated cholesterol can raise the risk of cardiovascular diseases, including heart disease and blood vessel-related conditions, by up to 40%. Individuals with high blood pressure, diabetes, existing heart conditions, hereditary hypercholesterolemia, or who smoke are at an even greater risk.
