What causes high cholesterol?

By age 10, children with FH often accept aortic lesions and thicker carotid arteries than siblings who didn't inherit the condition. Over time, the condition tin can pb to atherosclerosis (build-up of plaque) and narrowing of artery walls.

Plaques can be detected in almost a quarter of adolescents with FH. The signs of center disease can bear witness up decades earlier in people with FH compared to the general population, and their take chances for premature middle disease is 22 times greater.

Familial hypercholesterolemia can exist diagnosed through your cholesterol levels and your family history of high cholesterol or early-onset heart disease. The diagnosis can be confirmed by genetic tests.

Affecting approximately one in 500 people, hereditary high cholesterol is the result of a malfunctioning gene that causes simply half of the LDL receptors work to piece of work. Studies show that near 1 in 250 people may inherit a defective cholesterol-regulating gene from one parent.
