The average American adult carries about 5.6 grams of cholesterol circulating in plasma at any given moment — roughly the weight of a U.S. nickel. Careful mass-balance modeling of what lipoprotein particles need for structural integrity, plus what specialized tissues actually draw from the bloodstream each day, suggests the body's true circulating requirement is closer to 1.5 to 2.7 grams. The two- to four-fold surplus isn't toxic in itself.
Imagine a man named John. John is 55 years old, active, and diligent about his health. He eats a Mediterranean diet and walks three miles every morning. At his last annual checkup, his doctor delivered what seemed like excellent news: his LDL cholesterol - the "bad" kind - was 80 mg/dL. In the world of standard medicine, that is a gold-star score. John felt invincible.
Imagine a man named Mark. Mark is 48 years old, and lately, he feels like a shell of his former self. Every day around 3:00 PM, he hits a "wall" of exhaustion that feels like swimming through deep mud. His "brain fog" makes it hard to focus at work, and he has completely lost the "spark" for his hobbies and his relationships. He is tired, moody, and just wants to nap.
If your body were a blockbuster movie, cholesterol would be the character everyone loves to hate. We usually hear about it as the "villain" of the story—the bad guy responsible for heart trouble and clogged pipes. But if cholesterol is so truly "bad," why is it found in every single cell of your body? Why does your body work so hard to keep it around?
Imagine your body is a car, and your health is tracked by an odometer. For most of us, that odometer ticks up slowly and steadily. We might drive for 50 or 60 years before the engine starts to show significant wear and tear. But for some children, the odometer is spinning wildly out of control from the moment they are born. This is the reality of Homozygous Familial Hypercholesterolemia, or HoFH.
