All Wales Familial Hypercholesterolaemia Service




Familial Hypercholesterolaemia (FH) is a common inherited condition affecting around 1 in 250 of the UK population. It is caused by an abnormal gene which results in very high cholesterol levels in the blood.

People with FH, if untreated, are at an increased risk of early coronary heart disease. The FH Wales Service identifies and treats individuals and families in Wales.
