Electrolytes - Hypophosphatemia and Hyperphosphatemia

Phosphorus doesn’t always get the spotlight—but on test day, it’s a game changer. From energy metabolism to bone health, imbalances can wreck patients and trip you up on the shelf.

In this episode, Chris and Mars break down the most high-yield phosphorus scenarios you need to master: Refeeding Syndrome, DKA after insulin therapy, Hungry Bone Syndrome, antacid and binder use, Fanconi syndrome, CKD-related hyperphosphatemia, tumor lysis syndrome, and post-thyroidectomy hypoparathyroidism. 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 crash
• How insulin in DKA unmasks total body phosphate depletion
• The difference between Hungry Bone Syndrome and surgical hypoparathyroidis ...
