A quiet weekend on call begins with the retirement of Dr. Flow, a urologist who made the difficult look simple. A search for the perfect farewell wine—Pee No More—is abruptly interrupted by a sodium of 122. At the bedside, memorized algorithms begin to unravel under real clinical pressure. Through conversation, we explore ADH, aquaporins, and the physiology behind hyponatremia.

Why does volume override tonicity—and how can treatment itself become dangerous?

In Part 1 of Sodium Doom, we move beyond flowcharts and begin to truly understand sodium.

In medicine, we often order tests reflexively, trusting that numbers will guide us toward truth. But what happens when a test is elevated — or completely normal — and the patient remains a mystery? In this episode, we explore C-reactive protein, a familiar marker that is often misunderstood. Through one challenging patient, we uncover what CRP truly measures — and what it does not. And in doing so, we are reminded that not all suffering can be captured in a laboratory value.

In this episode of The Clinical Etymologist, we explore a common clinical paradox—anemia in the presence of abundant iron. Through a real bedside conversation, we move beyond memorized lab patterns and uncover the physiology that explains them. What does it mean when ferritin is high, yet the patient remains anemic? Why does the body hide iron during inflammation, and what role does hepcidin play in this process? Together, we follow iron’s journey—from absorption to storage—and discover where the system breaks down. By the end, anemia of chronic disease will no longer be a pattern to memorize, but a story you understand.
