High cholesterol is inevitable for some
If you have very high cholesterol levels in your blood it may be due to a gene defect. This form of inherited high cholesterol is called familial hypercholesterolaemia (FH). This problem affects 1 in 500 people and can cause cholesterol levels higher than 7.5mmol/L (desired level is less than 5mmol/L) in an adult and can lead to early heart disease in the form of angina or heart attack.
