"High levels of LDL cholesterol increase the risk of heart attack and stroke. Often labelled bad cholesterol, LDL builds up over time on artery walls, narrowing them and restricting blood flow."
"Genetics are the main driver of higher LDL cholesterol levels. Diets have smaller effects and it's not necessarily the total calories that count; it's the amount of saturated fat."
"Obesity per se has minimal effect on LDL cholesterol levels. But it affects other blood lipids much more, particularly excess body fat linked to higher levels of triglycerides and remnant cholesterol."
"From the age of 40, people in the UK are eligible for an NHS health check, which includes a cholesterol test. Your GP can easily assess your overall cardiovascular risk."
Cholesterol, primarily produced by the liver, is essential for building cells and hormones. High levels of LDL cholesterol, often termed bad cholesterol, elevate the risk of heart attacks and strokes. Genetics significantly influence LDL levels, while diet plays a smaller role, particularly saturated fat intake. Lean individuals can still have high cholesterol due to genetic factors. Obesity impacts other blood lipids more than LDL, increasing cardiovascular disease risk. Regular health checks from age 40 can help assess overall cardiovascular risk, considering factors like diabetes and blood pressure.
