Special Considerations for Aging Adults The fluid requirements for older adults are the same for younger adults. The Institute of Medicine of the National Academy of Sciences concluded in its 2004 Report that women need approximately 11.5 cups of total fluid a day from beverages and food while men need approximately 16 cups day.

Dehydration can be a serious problem in older adults. It is associated with increased risk of falls, urinary tract infections, dental disease, bronchopulmonary disorders, kidney stones, cancer, constipation, and impaired cognitive function.

Elderly adults tend to drink less than their bodies need for a number of reasons. With age, the body loses its ability to detect thirst. Some of the elderly also suffer from poor memory, immobility, or illness -- all of which can result in decreased fluid intake. In addition, certain medications can also block the thirst mechanism.

Encourage older adults to drink throughout the day even if they are not thirsty. Keep beverages that they enjoy nearby, possibly pre-poured in non-breakable cups and glasses that are easy to hold and hard to tip over. Also offer soups, popsicles, gelatins or other flavorful fluid-rich foods as often as possible.

If you think an older adult is not getting the fluids he or she needs or might be exhibiting signs of dehydration, discuss your concerns with a healthcare provider.
