    Great video, I would add an emphasis on another form of osmotic diuresis and that being from urea nitrogen in the setting of high protein intake. Not uncommon, young healthy men during bulking season will try to consume >2g/kg of protein thinking this protein goes to their muscle. A large part of that is converted into nitrogen containing compounds that they just pee out. Yes, you're peeing out that 16oz steak and chicken breast. Good way to know this is occuring is history and looking at their osm free water clearance and electrolyte free water clearance. These are usually discordant to a significant degree. Also, if someone has primary polydipsia for a prolonged period of time, they can wash out their medullary interstitium and respond to water deprivation like someone with partial nephrogenic DI due to gradient disruption.
