Hyponatremia is one of the most tested — and most misunderstood — electrolyte disorders. This episode breaks it down into a clear algorithm using volume status, osmolality, and urine studies so you can solve hyponatremia questions with confidence on exams and on the wards.

You’ll learn how to:

• Distinguish real vs “fake” hyponatremia in under a minute
• Use volume status and urine studies to pinpoint the cause
• Recognize classic vignettes like SIADH, cerebral salt wasting, and adrenal insufficiency
• Avoid the most dangerous board trap: osmotic demyelination syndrome
