Concretely when Water isn't transformed in the Bladder, the fluids aren't ascending, which causes thirst. But because the thirst isn't due to a deficiency of fluids, it isn't relieved by drinking.
As for the vomiting, it is caused by the accumulation of Water in the Stomach since the Bladder doesn't process it correctly anymore.
