Dehydration risk factors in older adults As we age, the amount of fluid in our bodies begins to decrease. This means there are fewer water reserves available for your body to use as you get older.
Why are the elderly more at risk of fluid balance?
Older adults are susceptible to dehydration and electrolyte abnormalities, with causes ranging from physical disability restricting access to fluid intake to iatrogenic causes including polypharmacy and unmonitored diuretic usage. Renal senescence, as well as physical and mental decline, increase this susceptibility.
What is a common cause of decreased fluid intake by the elderly?
Other common reasons for inadequate fluid intake and abnormal loss of fluids include: Decreased content of body water. Age-related changes in thirst sensation; decreased thirst response. Physical or mental inability to consume fluids independently.
Do older people have more water in their body?
