High cholesterol (hypercholesterolemia) can be inherited, but it's often the result of unhealthy lifestyle choices, and thus preventable and treatable. A healthy diet, regular exercise and sometimes medication can go a long way toward reducing high cholesterol.
High cholesterol typically doesn't cause any symptoms. In the vast majority of cases, the only true symptoms it may cause are emergency events. For instance, a heart attack or stroke can result from the damage caused by high cholesterol over time. These events typically don’t occur until high cholesterol leads to the formation of plaque in your arteries.
FH is agenetic disorder that can be passed on to children by either one or both parents. Itis one of the most common inherited metabolic diseases in the world, found in about 1 in every 500 people. FH is caused by genetic mutations that lead to abnormalities on the surface of liver cells responsible for clearing LDL(bad cholesterol) particles from the blood.
