                                While high cholesterol is a well-known risk factor for heart disease, an extremely low level can be just as dangerous. This is because the body vitally requires this waxy, fat-like substance to function, meaning a complete absence, or dangerously low levels (hypocholesterolemia), would be fatal and catastrophic for human physiology.
