Water imbalance, in which output exceeds intake, causing an imbalance in body fluids, is termed dehydration true salts are lost from the body in perspiration, feces, and urine. - adh secretion but no activity: in ndi, adh is secreted with normal stimuli (eg, increased plasma osmolality) but renal principle cells are insensitive to the adh action to increase water permeability insensitivity may involve mutations in the genes encoding the vasopressin 2 (v2) receptor, the g protein coupled with v2, or the aquaporin-2 channel.
