Dehydration in the elderly: a short review

R J Lavizzo-Mourey. J Natl Med Assoc. 1987 Oct.

Abstract

Dehydration is the most common fluid and electrolyte problem among the elderly. The usual causes of water loss are frequently absent in dehydrated elderly patients. Age-related changes in total body water, thirst perception, renal concentrating ability, and vasopressin effectiveness probably predispose to dehydration. Dehydration related to infection, high-protein tube feedings, cerebral vascular accidents, and medication-related hypodypsia are particularly relevant for elderly patients. Appropriate treatment depends on accurately assessing the water deficit and slowly correcting that deficit.
