Oral Rehydration Solution (ORS) is one of the simplest yet most effective ways to prevent and treat dehydration caused by diarrhoea and vomiting. It works by replacing the water and essential electrolytes such as sodium and potassium that the body loses during illness. While ORS is easily available and straightforward to use, many people unknowingly make mistakes while preparing or administering it, reducing its effectiveness and, in some cases, worsening dehydration.
The first and most important step is the preparation of the ORS․ The entire contents of the ORS packet must be dissolved in the amount of clean‚ safe drinking water specified on the packet‚ often one liter․ It is important that the specified amount of water is strictly followed․ Using less makes the formula too concentrated and using more dilutes electrolytes‚ resulting in a less effective ORS․ The formula should not be given with milk‚ fruit juice‚ soft drinks‚ tea‚ or other beverages as they alter the formula and can prevent absorption․
A common misconception is that ORS stops diarrhea․ ORS does not prevent the passage of loose stools‚ but does prevent dehydration‚ the most serious complication of diarrhea and vomiting․ That is why ORS should be administered as soon as diarrhea starts‚ not waiting until the person becomes dehydrated․ Vomiting is not a reason to stop giving ORS․ Instead‚ it should be given in small amounts‚ such as one or two teaspoons every few minutes․ Most people can gradually reach these levels; this may be enough to maintain hydration․
ORS is also sometimes stopped when the patient feels better‚ but active losses of fluids from diarrhea and vomiting should be replaced‚ and ORS continued after every loose stool and episode of vomiting until the diarrhea or vomiting has stopped․ Children and older people are especially prone to dehydration and should be monitored closely․ Mistakes can still occur in storage; ORS should be kept covered and used within 24 hours of preparation․ Any leftover solution after this period should be discarded, as bacterial contamination can occur. Fresh ORS should then be prepared if required.
Along with ORS, normal feeding should continue. Breastfed infants should continue breastfeeding, and older children and adults should resume light, nutritious meals as tolerated. Avoiding food unnecessarily can delay recovery and contribute to weakness.
Although ORS is highly effective for mild to moderate dehydration, it is not a substitute for medical care when warning signs develop. Medical attention should be sought if there is persistent vomiting preventing fluid intake, severe dehydration, blood in stools, high fever, reduced urine output, excessive drowsiness, confusion, or if diarrhoea lasts more than a few days. Infants, elderly individuals, pregnant women, and people with chronic illnesses may require earlier medical evaluation.
When prepared correctly and used promptly, ORS remains one of the most effective, affordable, and lifesaving treatments for dehydration. Understanding the correct method of preparation and avoiding common mistakes can significantly improve recovery and reduce the risk of complications.
