Medically, dehydration is a potentially fatal condition that can even result in death. It is a condition in which the body contains an inadequate amount of water required for normal functioning of the body. Rehydration is the process of replenishment of water, or water and electrolytes, lost through dehydration. |
Drinking plain water is not the only solution for dehydration. Plain water acts to restore only the quantity of the blood plasma, thus quenching only the thirst. Additionally, salts and sugars are required to sustain the delicate balance of electrolytes essential to efficient functioning. Hence, adequate water and electrolytes are essential to keep the body hydrated and this is what is achieved through rehydration.
In humans, generally, methods of rehydration include oral rehydration therapy or intravenous therapy.
Oral rehydration therapy (ORT) is the preferred treatment for mild dehydration. It is less expensive, easily available and is very effective treatment for dehydration associated with diarrhea, particularly gastroenteritis.
ORT consists of a solution of salts and sugars which is taken orally. The following recipe for Oral Rehydration Solution(ORS) is recommended by the WHO:
1 liter clean water
8 teaspoons sugar (or molasses)
1 teaspoon salt (about 2300 mg)
1/2 cup orange juice (for potassium)
Intravenous rehydration therapy (IRT) is the preferred treatment for severe dehydration, since this condition can lead to permanent injury or even death.
The best treatment for minor dehydration is drinking water and stopping further loss of fluid.
