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.
Statins— among the most commonly prescribed medications for lowering cholesterol — block a substance your liver needs to make cholesterol. This causes your liver to remove cholesterol from your blood. Statins may also help your body reabsorb cholesterol from built-up deposits on your artery walls, potentially reversing coronary artery disease.
