You’ll learn the classic presentations, the underlying pathophysiology, and the treatment pearls that show up again and again.We cover:Why refeeding syndrome causes a dangerous phosphate crashHow insulin in DKA unmasks total body phosphate depletionThe difference between Hungry Bone Syndrome and surgical hypoparathyroidismKey pitfalls of antacids and phosphate bindersWhat to do when CKD or tumor lysis drives phosphate dangerously highPerfect for med students gearing up for the surgery shelf—this one locks in both the physiology and the test-day clues.
