Rehydration Drinks

Diarrhea and vomiting can cause your body to lose large amounts of water, nutrients, and essential minerals called electrolytes. This happens faster and is more serious in babies, young children, and older adults.

Rehydration drinks replace fluids and electrolytes. Plain water doesn't provide necessary nutrients or electrolytes and may not be absorbed with diarrhea.

Rehydration drinks don't make diarrhea or vomiting go away faster, but they can prevent serious dehydration from developing.

Oral rehydration solutions (ORSs), such as Pedialyte, are used to prevent or correct dehydration in young children. ORSs contain the right mix of salt, sugar, potassium, and other minerals to help replace lost fluids.

Adult rehydration drinks should not be used for babies and young children. You can make an inexpensive rehydration drink at home. But do not give this homemade drink to children younger than 12.

Measure all ingredients precisely. Small variations can make the drink less effective or even harmful. Mix the following:

  • 1 quart water
  • ½ teaspoon table salt
  • 6 teaspoons sugar
