Diarrhea
If the child cannot go to a clinic or hospital, oral rehydration solution can be used. ("Oral" means "given by mouth"; a "solution" is a mixture.) Oral rehydration solution is a mixture of the most important things the body loses when it is dehydrated. These things are clean water, salt, and sugar. Some oral rehydration solutions have extra electrolytes, like potassium, in them also.
