Recurrent dehydration and salt loss might be a mechanism that causes chronic kidney disease, whereby increased plasma osmolarity activates both intrarenal (polyol-fructokinase) and extrarenal (vasopressin) pathways to drive injury. The authors propose that water and salt influence blood pressure through the timing and combination of their intake, affecting plasma osmolarity and intrarenal and extrarenal mechanisms of renal injury.
