How many milliliters of water do the elderly generally need per kilogram?

The elderly generally need about 25 to 30 milliliters of water per kilogram of body weight. As individuals age, their bodies undergo various physiological changes that may affect hydration status. Older adults often have a decreased sense of thirst, which can lead to inadequate fluid intake if not consciously monitored. Additionally, their overall body water content tends to decrease with age, making it crucial to ensure adequate hydration.

The recommendation of 25 to 30 milliliters per kilogram helps in providing a guideline that considers these factors, thus promoting optimal hydration and supporting overall health in this population. This amount may also account for fluid losses and changing hydration needs due to various factors like medication use, activity level, and health conditions commonly seen in the elderly.
