In physiology, dehydration is a lack of total body water that disrupts metabolic processes. [3] It occurs when free water loss exceeds free water intake. This is usually due to excessive sweating, disease, or a lack of access to water. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness ...
“Dehydration can have big effects on controlling blood pressure and on your general health.” For instance, blood pressure fluctuations can cause kidney problems and increase your risk for a ...

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.
Fluid replacement or fluid resuscitation is the medical practice of replenishing bodily fluid lost through sweating, bleeding, fluid shifts or other pathologic processes. . Fluids can be replaced with oral rehydration therapy (drinking), intravenous therapy, rectally such as with a Murphy drip, or by hypodermoclysis, the direct injection of fluid into the subcutaneous tis
In severe cases, dehydration can result in kidney damage, muscle damage and hypovolemic shock, in which blood levels decrease to the point that oxygen levels drop to dangerous levels (when blood ...
Youth athletes employ a variety of methods to lose weight, including dehydration, fasting, diet pills, laxatives, vomiting, and the use of rubber exercise suits. These practices result in “decreased plasma and blood volume, reduced cardiac outputs , impaired thermoregulatory responses , decreased renal blood flow , and an increase in the ...
[3] [27] The final step in treatment is to calculate the patients free water deficit, and to replace it at a steady rate using a combination of oral or IV fluids. [3] [27] The rate of replacement of fluids varies depending on how long the patient has been hypernatremic. Lowering the sodium level too quickly can cause cerebral edema. [27]
