Underlying causes of the syndrome of inappropriate antidiuresis stratified according to anatomical location. The etiologies in bold are more common in ambulatory patients and should be considered actively. The other causes should be assessed based on clinical signs using imaging of the head, nasal sinuses, chest, and abdomen. Created with BioRender.com. *There is also evidence that drugs associated with stimulating AVP release could, instead or additionally, enhance the effect of AVP on the kidney, thereby causing a nephrogenic form of inappropriate antidiuresis.

“We are now at the beginning of an age where we will have more information than we can possibly process. But let me remind you: Information is not knowledge. Knowledge is not wisdom. And wisdom is not foresight. Each grows out of the other, and we need them all. Before you become too entranced with gorgeous gadgets, remember that the goal is not to have more information, but to have more understanding.” — Arthur C. Clarke
