In a 2015 study published in Age and Ageing, 37% of men and women age 65 and older admitted to the emergency room presented with dehydration. Researchers found that, across the board, the patients ...
Dehydration can occur as a result of diarrhea, vomiting, water scarcity, physical activity, and alcohol consumption. Management of dehydration (or rehydration) seeks to reverse dehydration by replenishing the lost water and electrolytes. Water and electrolytes can be given through a number of routes, including oral, intravenous, and rectal.
Older children and adults should take frequent sips from a cup, with a recommended intake of 200–400 mL of solution after every loose movement. [1] The WHO recommends giving children under two a quarter- to a half-cup of fluid following each loose bowel movement and older children a half- to a full cup.
In physiology, dehydration is a lack of total body water that disrupts metabolic processes. [3] It occurs when free water loss exceeds intake, often resulting from excessive sweating, health conditions, or inadequate access to water. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness in ...

The recommended daily amount of drinking water for humans varies. [1] It depends on activity, age, health, and environment.In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for females over 18; it assumes about 80% from drink and 20 ...
The key guidelines for adults also apply to older adults. In addition, the following key guidelines are just for older adults: As part of their weekly physical activity, older adults should do multicomponent physical activity that includes balance training as well as aerobic and muscle strengthening activities.
The Holliday-Segar formula is a formula to help approximate water and caloric loss (and therefore the water requirements) using a patient's body weight. [1] Primarily aimed at pediatric patients, the Holliday-Segar formula is the most commonly used estimate of daily caloric requirements. [2]
