This is because of reduced water conservation by kidneys -LCB- reduction in Nephron numbers and reduced sensitivity of these nephrons to ADH -RCB- coupled with the reduced thirst sensitivity seen in older adults.

-RCB- elevated sodium level within kidneys, either as a result of pathological bottleneck such as reduced number of nephrons, or simply due to heightened intake - or both - may activate pro-inflammatory cytokines and chemokines in proximal tubular cells, may cause oxidative stress by activating ROS - producing NADH oxidase enzymes, or blood vessel constriction by inhibiting kidney arginine transport and nitric oxide synthesis; elevated renal inflammation, oxidative stress and restricted blood flow all can impair the efficacy of sodium excretion, more so combined (if extensive, it can also result in post-natal reduction of nephron units)
