The history of medicine is partly a history of what gets named. Scurvy existed for centuries before James Lind's 1747 trial, but sailors didn't die from a vitamin C deficiency — they died from something that had no unified identity, no category that made it treatable rather than inevitable. The philosopher Ian Hacking called this 'making up people,' but the same logic applies to making up diseases: once a condition acquires a stable name and classificatory home, it begins to shape what clinicians look for, what patients report, and which sufferers get counted. The sociologist Peter Conrad spent decades documenting 'medicalization' — the process by which ordinary human variation gets reclassified as pathology — and what he found was not a conspiracy but something more mundane and more consequential: category creation is not neutral description, it is also prescription. It determines who receives care, who gets excused from work, whose distress is legible to an institution. The practical edge of this is uncomfortable: every diagnosis you give is not just a finding but an act of classification that opens certain futures and forecloses others.

Think of the last patient whose presentation didn't quite fit the category you used. What did the category make visible — and what did it quietly delete?
