1/ Clinical Question: A person with chronic liver disease and alcohol misuse disorder is admitted to the hospital and is found to be hyponatremic. How can we formulate a differential and sort through various probable diagnoses? Also, what the heck is even beer potomania!? 2/ Background: Getting ready for my Peds and Medicine AIs, and for me, hyponatremia is this vague, nebulous concept creating a clinical syndrome of fatigue, muscle cramping, nausea, vomiting, headaches, and disorientation.
