Oral rehydration therapy (ORT) is a type of fluid replacement used to prevent and treat dehydration, especially that due to diarrhea. It involves drinking water with modest amounts of Oral Rehydration salts. Oral rehydration solution is on the World Health Organization’s List of Essential Medicines, the most effective and safe medicines needed in a health system. Globally as of 2015 oral rehydration therapy is used by 41% of children with diarrhea.
