Erin is only 17 years old and her total cholesterol is 600 mg/dL. Why do you think her cholesterol is so much higher than the others in her family who have familial hypercholesterolemia?

Familial hypercholesterolemia is a genetic disorder defined by having high levels of cholesterol in the blood. Maybe Erin doesn't care that much on having this disease. His lifestyle is not healthy. He does not exercise and eats everything he wants not thinking about the consequences that it may give.
