Does anyone know what causes urine to become more concentrated when you don't drink enough water?
I have a few ideas, I was thinking it was a release of ADH from the pituitary gland, but I'm not very sure.
Thanks.

That will be the lack of water.

The ADH should definitely be one thing that would have an effect.

Mainly ADH
Also aldosterone

low water --> ADH --> aldosterone --> distal convoluted tubule more permeable --> water comes back --> urine more concentrated
