Rehydration
From Wikipedia, the free encyclopedia
Rehydration is the replenishment of water, or water and electrolytes, lost through dehydration.
In humans, methods of rehydration include oral rehydration therapy or intravenous therapy. As oral rehydration is less painful, less invasive, less expensive, and easier to provide, it is the treatment of choice for mild dehydration. Because severe dehydration can rapidly cause permanent injury or even death, intravenous rehydration is the initial treatment of choice for that condition.[citation needed]
If someone exhibits signs of moderate to severe dehydration, medical attention should be sought.
