Magnesium derangements are sneaky but high-yield! In this episode, Chris and Mars break down hypomagnesemia and hypermagnesemia across classic scenarios you’ll see on the wards and on exams. Learn why magnesium is the key to fixing refractory hypokalemia and hypocalcemia, how alcohol, PPIs, and refeeding syndrome trigger dangerous lows, and why CKD patients with laxatives or OB patients on mag drips can tip into life-threatening highs. We cover exam-ready pearls like Torsades treatment, reflex monitoring, and safe bowel prep alternatives.
