AGING AND THE KIDNEY: CLINICAL IMPLICATIONS.
Beyond the age of 30, kidney size begins to decrease, and there are accompanying decreases in total renal blood flow, outer cortical flow, glomerular filtration rate and the ability both to conserve and to excrete sodium. There is also a decline in concentrating ability and possibly in diluting ability. These changes make the elderly patient [...]
THE RELATIONSHIP BETWEEN DEHYDRATION AND PAROTID SALIVARY GLAND FUNCTION IN YOUNG AND OLDER HEALTHY ADULTS
BACKGROUND: Saliva is essential for the maintenance of oral health. The primary constituent of saliva is water and, traditionally, decreased body water homeostasis has been linked with salivary dysfunction. This is consistent with the greater prevalence of dehydration and salivary gland dysfunction among the elderly. However, this association between dehydration and salivary dysfunction has never [...]

REDUCED THIRST AFTER WATER DEPRIVATION IN HEALTHY ELDERLY MEN.
To determine whether responses to dehydration are altered with age, we investigated the thirst, fluid and electrolyte responses, and hormonal responses to 24 hours of water deprivation in seven healthy active elderly men (67 to 75 years old) and seven healthy young men (20 to 31 years old) who were matched for weight loss during [...]
Abnormalities of water metabolism in the elderly.
Hypernatremia is a frequent problem at the extremes of age, but particularly so in elderly individuals. Changes in the physiological responses to water deprivation with increasing age may be of particular interest in understanding the pathogenesis of hypernatremia in the elderly. When comparing healthy elderly men to younger controls, there are differences in the response [...]
Response to dehydration in elderly patients in long-term care.
Elderly patients in long-term care have a high plasma osmolality (pOSM) and associated increased mortality. In these patients, we examined pOSM, thirst (visual analogue scale, VAS) and arginine vasopressin (AVP) response to 16-hour dehydration and 2-hour rehydration. Twelve patients were randomly divided into two groups (A & B). Group A had their fluid balance monitored [...]
Dehydration and provision of fluids in palliative care. What is the evidence?
OBJECTIVE: To provide a clinical review of issues surrounding reduced fluid intake in palliative care patients and a practical approach to care for these patients. DATA SOURCES: Medline was searched from 1980 to 1995 for articles concerning dehydration in dying patients. In addition, the law databases QUICKLAW, WESTLAW, and MEDMAL were searched. STUDY SELECTION: Key [...]
