Oral rehydration solution
Oral Rehydration Solution
Oral rehydration solution (pronounced: /ˈɔːrəl riːhaɪˈdreɪʃən səˈluːʃən/), often abbreviated as ORS, is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhea. It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium.
Etymology
The term "oral rehydration solution" is derived from the method of administration (oral), the purpose of the solution (rehydration), and the form it takes (solution).
Composition
An oral rehydration solution contains water, small amounts of sugar, and essential electrolytes like sodium and potassium. The World Health Organization (WHO) has a standard recipe for ORS which includes:
- Sodium chloride
- Glucose, anhydrous
- Potassium chloride
- Trisodium citrate, dihydrate
Usage
Oral rehydration solution is used to treat dehydration caused by diarrhea, a common problem in developing countries. It can also be used in the treatment of cholera, rotavirus, and other diseases that cause water loss.
