Oral rehydration therapy (ORT) using a low solution recommended by the World Health Organization (WHO), has reduced the number of dehydration deaths caused by vomiting and diarrhea at approximately one million per year. Recent research suggests that the use of oral rehydration solutions has advantages over conventional therapy, and we should make an effort to encourage the use of ORT as first choice for rehydration.

For practical purposes rehydration can be achieved using solutions with high sodium content, ie 75-90 mmol / L. These are called Oral Rehydration Solutions (ORS). Prophylaxis of dehydration and maintenance involves solutions with 45-60 mmol/L of sodium. They are called maintenance solutions. Fruit juices are ineffective due to their high carbohydrate concentration as well as poor osmolality and sodium concentration. The individualized dietary management of the patient during acute diarrhea is the key and should be emphasized.
