I've created a short video on the approach to hyponatremia in the clinic. It is aimed at young physicians. Within 10 minutes you'll learn how to figure out the cause of hyponatremia in your patient, by assessing volume status, and measuring sodium and osmolality in urine. The video has a few examples, but the approach can be applied to all causes of a hypotonic hyponatremia. Let me know what you think!
