Is "thick blood" a diagnosis? Here, I explain why this term is a medical oversimplification—and what really lies behind thrombosis, hypercoagulability, and anticoagulation. In this episode, I discuss: — Why "thick blood" doesn't exist as a disease—and what lies behind this concept — Dehydration and hematocrit: when blood is actually thicker — Polycythemia vera and thrombocytosis—the real pathology — Atrial fibrillation: a clot in the ear and why you need an anticoagulant, not a "blood thinner" — The coagulation system: — Congenital and acquired thrombophilias Join me!
