[Thirst and fluid metabolism in old age].
Water balance depends on an intact regulating mechanism for volume and osmolality. While thirst has a very important function in osmoregulation, in repletion of volume deficits it is of little importance. A thirst deficit is common in old persons and often a cause of dehydration in geriatric patients. Diagnosis, treatment and prevention of dehydration are discussed.
