ELI5: Why do people still urinate even if they are dehydrated?
gpt
The cells in your body create small amounts of waste that get dumped into your blood stream. Your kidneys filter that out and that creates your pee. That process continues during mild dehydration.

Dehydration has stages. Signs that things are getting really serious include stopping sweating then stopping peeing. If you stop urinating then your body has decided its worth letting your body become toxic to hold onto moisture.
